One of the most serious threats to potential water contamination occurs during the irrigation of crops. Modern agricultural scientists have developed systems, which inject insecticide chemicals, as well as fertilizers, into the irrigation water as the flow towards the exit hole. Because of the siphoning effect, some of this contaminated water may reenter the potable water supply.
Since this poses a serious threat to the public, government regulations require the use of backflow prevention during chemical irrigation. This type of back flow prevention is called “chemigation,” when it is employed to prevent the reflux of chemicals, and “fertigation,” when it is employed to prevent the reflux of fertilizers injected into the irrigation water as it flows towards the exit hole.

Insecticides are such dangerous substances,that chemigation employs a series of back flow checks to protect the safety of the public. The first valve employed is called a “spring loaded check valve.” A check valve is simply a one way flap, or stopper, which prevent the reflux of liquid flowing in a tube. When the water flows in the right direction, it pushes the stopper out of the way, when the water is still, the pressure of the liquid trying to reflux pushes the flap or stopper shut. In a spring loaded check valve, a spring pushes the flap or stopper back against the valve opening, (valve seat), before the water has a chance to do it.

The reason for employing a spring loaded valve is logical. Liquid flows in random directions. With regular stop valve, when the flow stops and the water begins to back up, some of the water flows against the valve lip or stopper and pushes it shut, but some of the water flows around the flap, and refluxes. Check valves work because the amount of water that refluxes before the valve shuts is small. But when the downstream water is contaminated with dangerous insecticides that are poisonous even in small amounts, then even a little water refluxing could be deadly. Therefore, scientists rely on the spring loaded check valve, which closes the opening much quicker.

Even the spring loaded check valve does not close quickly enough to prevent all of the contaminated liquid from refluxing. Therefore, chemigation valves employ additional types of backflow prevention, which includes a downstream low vacuum drain that releases contaminated water and also protects the upstream check valve from the possibility of continual reverse pressure coming from downstream. The chemigation backflow prevention device also includes an air and vacuum relief valve, which prevents siphoning by allowing air to enter the irrigation tube, whenever flow strops and pressure drops in the tube. Finally, the whole system includes an irrigation port, downstream from the check valve, for adding the chemicals and fertilizer. The specificity of the agricultural backflow prevention system, and the intricacy of the regulations which protect the public, should deter anyone from taking our supply of safe fruits and vegetables for granite.

Tap water is absolutely the worst kind of water in the world because most all tap water is contaminated.
“…fluoride (that is added to municipal water) is a hazardous waste product…for which there is substantial evidence of adverse health effects and, contrary to public perception, virtually no evidence of significant benefits,” says Dr. William Hirzy, Vice President, Chapter 280 of the National Treasury Employees Union, EPA headquarters in Washington, D.C.

At least 22% of all American children now have dental fluorosis as a result of ingesting too much fluoride, according The Centers for Disease Control.
That rate may be 69% in children from high socioeconomic-status families and those who live in fluoridated communities, according to a July 1998 report from The American Academy of Pediatric Dentistry and corroborated in several reports published since 1995 in the Journal of the American Dental Association (JADA-see below). Fluorosis is the discoloration and, in advanced cases, the pitting of teeth. Whitening is not effective.

The more monumental health concern is that dental fluorosis is not the only harmful health effect that results from overexposure to fluoride . Fluoride has been linked in government and scientific reports to a wide range of harmful health effects, including: bone and tooth decay (including dental and skeletal fluorosis, bone pathology, arthritis, and osteoporosis) Alzheimer’s, memory loss and other neurological impairment, kidney damage, cancer, genetic damage, and gastrointestinal problems.

In addition, fluoride has been discovered to leach lead from old water pipes and soldering material, which has resulted in increased lead levels in people .

Americans, even in unfluoridated communities, are suffering serious harmful health effects from overexposure to fluoride due to its widespread and uncontrolled use. Fluoride can be found in any food or beverage made with fluoridated municipal water. Less than 2% of Western Europe drink fluoridated water compared to over 60% of the United States population.

Federal and state public health agencies and large dental and medical organizations, such as the American Dental Association, continue to promote fluoride despite growing evidence that it is harmful to public health and the environment. This is also despite EPA�s own scientists, whose union, Chapter 280 of the National Treasury Employees Union, has taken a strong stand against fluoride.

Fluoride is not an essential nutrient. It has never received “FDA Approval” (U.S. Food and Drug Administration). It is listed as an “unapproved new drug” by the FDA, and as a “contaminant” by the EPA. Although calcium fluoride can occur naturally, the type of fluoride (sodium) added to municipal water is a hazardous waste product of the aluminum industry, phosphate fertilizer industry, and other industries.

Kangen Water is a safe and healthy drinking water partly because it takes out all the fluoride from your tap water. Kangen Water also brakes up the water clusters into smaller micro-cluster going from a 15 to 100 sided structure to a 5 sided structure. The small the water cluster the smaller easier the water gets into your system. You have read why not to drink tap water so now please take some time to research why you would want to drink water from an Enagic Water Ionizer. Do your own research as I have done here.

My digestion is back to normal and my constipation is gone after only 5 days. After 7 days I noticed that I am no longer tired and exhaustion from my anemia which was bothering me for the last five years for 4 to 5 days a week I was feeling tired with no energy in the middle of the day and every day I would not know if I was going to feel good or not. I was talking supplements and they did not work anymore because I was drinking acidic water without even knowing. Now I have lots of energy and no more fatigue feelings. My acid reflux is left and I can eat any kind of foods and vegetables without causing me acid reflux or heartburn. I also noticed that I lost 10 lbs in about a month and I keep the weight off without any changes except drinking the alkaline water.

This is one of the best solutions I have found in many years. It saves me a lot of money in the long term by not buying any more medications, many other supplements and doctor and emergency room visits that were not helping me to take care of my symptoms. I counsel you to start drinking the alkaline Kangen Water and see for yourself the outcome and start helping other people that want to sustain or prevent so many diseases that can be reversed just by simply shifting the water that you drink everyday.

So far a few of my relatives and friends started drinking the alkaline water and decided to procure the LeveLuk SD501 Water Generator and now they enjoy the health benefits and have more energy, blood sugar levels decreased and stabilized, acid reflux and sleeping evils are no longer an issue. They also use the 5 types of water for cleaning, sterilizing, disinfecting counters, pressure sores, rashes, acnee, eczemas, using the Beauty water as a face tonner, besides drinking and cooking with the alkaline ionized water. Many of them never thought that they would be giving such a good Kangen Water Review

It is Kangen water that is making a diferance in people’s health not acidic so called health drinks. I tell everyone I run into about how my life has been transformed by this water and if you give it a opening you too will be a altered peorson. You don’t have to be fat or unhealthy to get the great results form Kangen Water.

I have some facts that I feel you must be made aware of about Kangen Water, I ask you to spend a few minutes reading and watching a number of valuable videos.

Some people are going to say to themselves, “I don’t want to misuse that much time”, even if this could save their lives. I just say good luck to those people, for what is one to do. However most of us give great consequence to our health and want to hear more. I know now everyone must have some sort of plan this mine!!

As you are aware, at my age we are known to bear with many maladies, weight problems, osteoporosis, diabetes, high cholesterol, hypertension, arthritis, and acid reflux and worst of all cancer.

50 years ago, one person in 3,000, in their lifetime, would endure with Cancer, today that figure is 1 in 3, soon to be 1 in 2. Scary isn’t it.
Well, I want to tell you I am not anxious as I used to be. For the last 8 months I have been drinking an Enagic Kangen Water alkaline water which has a pH of 9.5, by drinking this water my body has a pH level of 7.3. With this pH level I am sheltered from any of the above illnesses.
This water has been in use for over 40 years in most major Hospitals in Japan. 6% of all homes use the Kangen water unit.

We are cheerful to say that the kangen water unit is now available here.

Here is the reason, I know I will not have cancer.

Way back in 1931 Dr Anton Walberg acknowledged the Nobel Prize for discovering that Cancer, or any illnesses cannot establish itself in an alkaline body, whereas, in an acidic body illnesses thrive.
Yes we have known a long time, yet, cancer continues to growth because of many different reasons. Remember, one must have an alkaline body, to be protected I would like to give a little testimonial.
For forty years I have had asthma, and had it pretty terrible. Those of us who have suffered keep in mind the bad days. When to get a little relief we would take a puff of Ventrolin. We would use it until it made us nearly sick.
I have been on different inhalers for all these years. The last one I used improved me extremely. Isn’t it that something I have forgotten the name. I’ll commit to memory it later.
As I said I have been drinking Kangen water for about 8 months, three months ago I realized I had ignored to take my inhaler, I found that I had not taken it for a week and here I was, my chest was giving me no trouble at all.
I have not taken my spray for about 5 1/2 months and to tell you the truth I feel better today than I have for 40 years. Thanks to my Kangen Water Distributor.

I have always maintained that the path to good health is not full of small stomachs and sore legs. I am very over weight at 305 lb’s but keep reading and you’ll see why I am writing a post on health. A year ago I was approached by a friend at my golf club and was given a DVD about Kangen water that I didn’t take a look at for about 6 months. Once I watched it I thought that the product was amazing but still didn’t have cause to go over and talk to him more about it. That was a huge mistake on my part, huge! Since I have been taking Protandim and drinking Kangen water for the past 7 and a half weeks I have lost 20 lb’s and feel wonderful! I was 325 lb’s and I didn’t cary it very well either.

In-fact even though I am 6 foot 2 I looked like a big fatso! I was a steer wrestler in my younger days and am a golf pro today. I guess you could say I’m a bit country and a bit country club always have been. That aside my appearance is vital to creating a good first impression and at 325 it was a challenge. I was very close to getting a gastric by pass am am so so so happy I never took the steps toward getting one and instead found Kangen. What is Kangen Water? Kangen water is high alkaline (8.5 to 9.5 Ph), micro clustered, oxygenated active hydrogen having water. Say that five times fast! The first benefit of drinking kangen water is that it raises the alkalinity of your internal organ tissue slightly. Do to homeostasis you blood will always run at 7.36 Ph but you can change that Ph in your tissue to slightly alkaline. This is important because aseptically cancer can not live in a alkaline oxygen rich environment. What to possibly prevent cancer, drink Kangen water.

Next it’s water clusters are 5 to 6 deep instead of all other waters clusters at 15 to 100. This is important because the smaller the water clusters the easier they get into your cells. The easiest way to describe it is that are body is like a fish tank and when the tank gets dirty the fish get sick. You don’t drop pills into the tank and hope it gets better do you? How strange that that is how we take care of our body when it gets sick. Well with fish when the tank gets dirty we take the fish out clean or replace the water and put the fish back in and they thrive. That is what your doing by supper hydrating with kangen water your replacing the acidic toxin filled water in your body (7 gallons is in the average person) and replacing with pure mineral rich and alkaline water.

That is why Kangen Water works. Your body is the miracle not the water. All kangen water is doing is giving your body what it needs to thrive. I have lost 20 lb’s in 7 and a half weeks and have no swelling in my legs. I have more energy that I have had in years and most of all I have hope for tomorrow and that is priceless.

Water is life’s mater and matrix, mother and medium. There is no life without water, but water in its raw state is not suitable for drinking. It contains numerous contaminants, which can be dangerous to human health.

But, thanks goes to Science that has invented devices to shield civilization against such aqua ailments. A water purifier is one of such devices that purify our drinking water. A water purifier is a wonderful device that converts raw water so that it tastes like nectar; therefore by this process it makes ordinary tap water perfectly suitable for drinking.

Health Benefits of a Water Purifier:

A water purifier is very beneficial for healthy living. Ordinary untreated water can contain numerous contaminants including bacteria, algae, viruses, fungi, minerals, and man-made chemical pollutants that cannot be seen with the naked eye. These contaminants are very pernicious for one’s health.

A water purifier kills these organisms and filtrates the contaminants to make the water perfectly fit for drinking. Thus water purifiers save us from numerous dangerous bacterial and viral diseases that easily spread when water becomes contaminated.

Water Purification Techniques:

Different water purifiers use different techniques of purification. The common techniques used to purify water include boiling, carbon filtering, distilling, reverse osmosis, ion exchange, electrode ionization, water conditioning and plumbo-solvency reduction.

Carbon filtering: This technique is commonly used in home water filters. Charcoal, a form of carbon with a high surface area due to its mode of preparation, adsorbs many compounds, including some toxic compounds. The water is passed through activated charcoal to remove such contaminants. Granular charcoal filtering and sub-micron solid block carbon filtering are the two types of carbon filtering systems.

Granular charcoal is not very effective for removing contaminants such as mercury, volatile organic chemicals, asbestos, pesticides, disinfections byproduct (trihalomethanes), mtbe, pcbs etc. The sub-micron solid block carbon filter is the better system that removes all of the contaminants.

Home water filters drinking water sometimes also contains silver. These small amounts of silver ions can have a bactericidal effect.

Reverse osmosis: The reverse osmosis water system is the technique in which mechanical pressure is applied to an impure solution to force pure water through a semi-permeable membrane. The process is called reverse osmosis, and is theoretically the most thorough method of large-scale water purification.

Ion exchange: Most common ion exchange systems use a zeolite resin bed and simply replace unwanted Ca2+ and Mg2+ ions with benign (soap friendly) Na+ or K+ ions. This is the common water softener. A more rigorous type of ion exchange swaps H+ ions for unwanted cations and hydroxide (OH-) ions for unwanted anions. The result is H+ + OH- → H2O. This system is recharged with hydrochloric acid and sodium hydroxide, respectively. The result is essentially deionized water.

Electrodeionization: It includes passing the water through a positive electrode and a negative electrode. Ion selective membranes allow the positive ions to separate from the water toward the negative electrode and the negative ions toward the positive electrode. It results in high purity de-ionized water. The water is usually passed through a reverse osmosis unit first to remove nonionic organic contaminants.

Water conditioning: This is a method of reducing the effects of hard water. Hardness salts are deposited in water systems subject to heating because the decomposition of bicarbonate ions creates carbonate ions that crystallize out of the saturated solution of calcium or magnesium carbonate. Water with high concentrations of hardness salts can be treated with soda ash (Sodium carbonate) that precipitates out the excess salts, through the common ion effect, as calcium carbonate of very high purity. The precipitated calcium carbonate is traditionally sold to the manufacturers of toothpaste.

Plumbo-solvency reduction: In areas with naturally acidic waters of low conductivity (i.e. surface rainfall in upland mountains of igneous rocks), the water is capable of dissolving lead from any lead pipes that it is carried in. The addition of small quantities of phosphate ion and increasing the pH slightly both assist in greatly reducing plumbo-solvency by creating insoluble lead salts on the inner surfaces of the pipes.electric car motor|electric car motor|electric car motor

As a refined version of charcoal, activated carbon is made by super heating organic material like wood or coconut shells. This super heating drives out impurities and causes the surface area of the resulting material to become tremendous. It is this large surface area that allows this substance to be used to clean water.

For years the process of cleaning water with activated carbon in water purifiers was referred to as absorption. This term refers to what a sponge does with water and it is easy to visualize the activated carbon acting like a sponge, soaking up contaminants. However, this is not actually how the process works. The molecules inside the activated carbon are passive because they are connected to other molecules around their entire perimeter. The molecules on the surface are not as “happy” because they are exposed on one side without another carbon molecule as company. Therefore, these exposed carbon molecules are actively seeking something to “hook to” or bond with. As impurity in the water pass the activated carbon these exposed molecules bond with the impurities through a process of adsorption. When the entire surface area of the activated carbon is covered with impurities is quits adsorbing impurities.

Once the entire surface of the activated carbon is completely covered with impurities the water purifier quits working. At this point it is possible to “re-activate” the carbon by reheating it and thus driving off the impurities in the air. However, since this is a relatively tricky process and may result in some impurities being picked up from the oven it is probably best to leave this to the experts and simply replace the carbon in the water purifier.

Contact time is the primary attribute that determines the efficiency or effectiveness of water purifiers. Image a flow of water that is moving at a hundred miles per hour though a thin mat of activated carbon. In this scenario not much is going to happen because the water is not in contact with the activated carbon for a sufficient period of time. Therefore the higher the volume of water that the water purifiers is trying to clean the larger the filter should be. This is why a relatively small activated carbon water purifier works great on an ice maker in your home. Not much water is moving though the filter’s quarter inch line. This contact time constraint also indicates that it is better to place several medium sized water purifiers around the house than to install a water purifier for the whole house unless you are will to install a very large filter that will have to handle showers and baths.

Now we know that the activated carbon adsorbs rather than absorbs impurities and that contact time is the most important component in the high quality water equation. These facts indicate that it is best to add several water purifiers where needed and to change the activated carbon filters on a regular basis.electric car motor|electric car motor|electric car motor

Mechanical Filtering
This is simply having a barrier that has perforations smaller than what it is that you intend to remove. This process of filtration removes minute elements that are floating in the water like dirt, silt, sand, sediment, rust and additional un-dissolved substances. As water flows through the media the substances are trapped or inhibited and for practical purposes removed from the water.

Depending on the class and/or kind of the filtering media, particulates as tiny as 0.5 microns are able to be stripped from your drinking water. For the purpose of reference, a micron is equal to 1/25,000 of an inch, the diameter of one filament of your hair is around 100 microns.

A variety of substances are used to manufacture mechanical filtering media. Ceramics and a variety of resins comprise the greater part of this kind of water filtration.

Oxidation-Reduction or Redox Process
Redox is a process in which electrons of one atom gets passed on to another. What this means is that if you mix two dissimilar metals you get an electrochemical process that oxidizes a multitude of chemicals regularly discovered in ground water in addition to our public water stores, and as a result eliminating them from the water. The heavy metals such as aluminum, cadmium, lead and chromium are removed by the electrochemical process. Metals such as these are attracted to the filter’s media, much like to a magnet.

KDF Fluid Treatment, Inc., makes the most extensively used media of this nature, a coper and zinc mixture, and has retained the patent ever since 1987.

Adsorption: Activated Carbon
Activated charcoal soaks up organic elements that may make your water stink and taste awful. Also it has the ability to get rid of pesticides, chlorine and its byproducts. This material is extremely porous having a immense surface area, to the extent that the carbon in an average countertop filter could have a surface area of about 200 football fields.

The term “activated” refers to a process by which the carbon is made more porous than it would be on its own. The activation process is effected by using steam, a chemical process or by controlled production processes while creating the carbon.

Here is an explanation of how activated carbon works: As water flows through the filter dissolved chemicals attach themselves to the carbon allowing the water to keep going. This process is known as absorption.

Activated carbon will fall into one of three categories: carbon block (CB), granulated activated carbon (GAC) and powdered activated carbon (PAC). The CB category works better at higher pressures, where the granulated activated carbon costs less and performs well with public water supplies. The PAC kind is not use residentially as often.

Some of the types of material used for manufacturing activated carbon are coal, wood, lignite, coconut shell and such. Coconut shell is thought of as the ideal material when creating filters for drinking water due to its propensity to make the water taste better.

Be advised that water filters do not totally get rid of contaminates, filters will just lessen them. However a superior water filter will remove nearly all of the undesirable contaminants it is designed to eliminate. Make it a point to get only water filtration systems certified by the National Sanitation Foundation (NSF) These filters will have been tested to verify the manufacturer’s claims. Therefore you will know what you are buying.

If there are too many wastes to take care of, they are dumped in various organ systems, like the heart, or the pancreas, or the liver, or the colon, or in other locations.

Sometimes these wastes are left on the walls of arteries, and over many days can spread throughout the body.

The break-down of this disposal process, especially of acid wastes, is how we define the aging process.
To slow down and reverse this direction, you must begin removing acid wastes from your body.

The best way we have found to do this is to drink Kangen water. Kangen Water, having a pH of between 8.5 and 9.5 on demand , will first neutralize harmful stored acid wastes, and if you consume it every day, will gently remove them from your body. I advise that you drink a half once on kangen water for every pound you are so if your 150 lbs drink 75 oz of kangen water a day. Yet, since the water is ionized, it will not leach out valuable alkaline minerals like calcium, magnesium, potassium, or sodium.

Japanese Doc’s have treated their patients for over four decades with alkaline water. They believe that the immune system looses its power to throw off disease when the body becomes too acidic.
They tell there patients to start drinking Kangen water.

Asian medicine assigns two categories to human diseases: communicable and adult. Contagious or communicable diseases are caused by viruses and bacteria.

Influenza, the common cold, aids, plagues, all fall into this category, and medical doctors are quite proficient at treating them. Adult diseases include heart disease, cancer, diabetes, high blood pressure, gout, arthritis, kidney diseases, hemorrhoids, asthma, hay fever, allergies, obesity, tooth and gum disease, skin disorders, and many others.

They are cause by poor circulation, by deficient cellular activity, and by the accumulation of acid wastes in the body. Asian medicine says that many adult diseases can be treated by alkalizing the bloodstream.
Medicine of America does not attempt to remove acid wastes from physiological system; so today’s modern medicine is rather deficient in treating adult diseases even if the medicine cures the disease, if acids are not removed from the body, the treatment’s effectiveness will at best only be temporary The solution is the Enagic water ionizer

I personally keep one in my backpack when I go hiking and what made me fall in love with the MSR Hydromedary Hydration Bag is that when filling it up it has a low profile, ergonomic handle and wide-mouth opening for no-hassle filling. If you have filled up a camel bag, before, then you know why the specially designed handle is so nice to have. Another thing I just love about this camel bag compared to others I have is that it can handle being frozen. To have a frozen pack on your back while you’re hiking can keep your body temperature down and also provides the convenience of having cold water, other brands of camel bags will crack & leak when frozen. Along with being durable this pack is BPA-free, and with the food-grade lining you do not have to worry about dealing with chemicals leaking into your water. When drinking from your Hydromedary Hydration Bag it has a simple bite valve and you just bite down halfway for maximum flow, and when you’re done drinking, it has a simple shut off valve that you just rotate a quarter turn in either direction to close the water flow and conserve your water.
Now you might wonder how hard it is to clean it. You just need to do the following:

* Disassemble the bite valve for cleaning.
* After each use, wash reservoir thoroughly with soap and water, rinse and hang open until completely dry.
* To sanitize, fill reservoir with a diluted bleach solution (1 tablespoon per liter) and let sit over night before rinsing and drying.
So remember the next time you are out hiking, biking, or just jogging with your dog and you get thirsty stay hydrated with your MSR Hydromedary Hydration Bag.
