Water Filtration

Reverse osmosis is based on the natural process of osmosis which involves the selective movement of water from one side of a membrane to the other. Reverse osmosis ( also known as hyper filtration ) is the same process used by a human body to filter out contaminants. Particles or impurities can be removed from a solution through the process of reverse osmosis when the solution is forced through a semi-permeable membrane which allows the passage of water but rejects ions like sodium and calcium or contaminants like bacteria or urea. Gore-tex is a common semi permeable membrane. Gore-tex fabric contains an extremely thin plastic film into which billions of small pores have been cut. The pores are big enough to let water vapor through, but small enough to prevent liquid water from passing through.

Reverse osmosis also involves a process known as crossflow, which allows the membrane to clean itself. As fluid passes through the membrane some of the fluid continues downstream, sweeping the contaminants away from the membrane. For reverse osmosis to occur, pressure must be applied to the fluid. The most common method of applying pressure is the use of a pump. The higher the pressure applied, the greater the force created. As the concentration of the fluid being rejected increases, the force required to continue concentrating the fluid increases. Pressure is exerted on the area containing the concentrated solution, which forces the water molecules across the membrane to the area of the fresh water.

Reverse osmosis has become very popular in recent years because it not only filters water but also rejects bacteria, salts, sugars, proteins and other elements that have a molecular weight of greater than 150-250 Daltons; a unit of measurement so small it can only be seen with a microscope.

The process of reverse osmosis is of immense benefit to mankind. Its applications are wide ranging with the most common use being for purifying water in both commercial and residential water filtration systems. It is also used to desalinate seawater as well as to purify liquids in which water is an undesirable impurity, for instance in glucose or ethanol.

Many homeowners unhappy with the quality of their drinking water are turning more and more to either a variety of water filtration systems or to one source or another of bottled water, although the latter is slowly becoming less prevalent every day. However, for those whose source of drinking water is a well or for those who live near a well, wells have become a major health issue making either of these choices far better than doing nothing. Why? People have been drinking from wells for centuries, haven’t they? Yes, they have, but since the Industrial Revolution in the late 19th century, more and more wells have become increasingly contaminated, and one particular type of well that has suffered more than most is called an injection well.

What is an injection well?
An Injection well is a device that places fluid deep underground into porous rock formations, such as sandstone or limestone, or into or below the shallow soil layer. These fluids may be water, wastewater, brine (salt water), or water mixed with chemicals.

The Underground Injection Program (UIC) defines an injection well as:

• A bored, drilled, or driven shaft, or a dug hole that is deeper than it is wide,
• An improved sinkhole, or
• A subsurface fluid distribution system.

How an injection well looks (is constructed) depends on the fluid injected and the depth of the injection zone. For example, deep wells that inject hazardous wastes into isolated formations far below the Earth’s surface are designed to provide multiple layers of protective casing and cement. Shallow wells that inject into or above drinking water sources are usually of simple construction and inject non-hazardous fluids.

What are injection wells used for?
Injection wells have a range of uses that include waste disposal, enhancing oil production, mining, and preventing salt water intrusion. Widespread use of injection wells began in the 1930s to dispose of brine generated during oil production. Injection effectively disposed of unwanted brine, preserved surface waters, and in some formations, enhanced the recovery of oil. In the 1950s, chemical companies began injecting industrial wastes into deep wells. As chemical manufacturing increased, so did the use of deep injection. Injection was a safe and inexpensive option for the disposal of unwanted and often hazardous industrial by-products.

In an effort to turn things around, in 1974, Congress passed the Safe Drinking Water Act (SDWA). Part of SDWA required EPA to report back to Congress on waste disposal practices, and develop minimum federal requirements for injection practices that protect public health by preventing injection wells from contaminating underground sources of drinking water (USDWs).

The UIC Program protects USDWs from endangerment by setting minimum requirements for injection wells. All injection must be authorized under either general rules or specific permits. Injection well owners and operators may not site, construct, operate, maintain, convert, plug, abandon, or conduct any other injection activity that endangers USDWs.

The purpose of the UIC requirements is to:

• Ensure that injected fluids stay within the well and the intended injection zone, or
• Mandate that fluids that are directly or indirectly injected into a USDW do not cause a public water system to violate drinking water standards or otherwise adversely affect public health.

After years of telling people chemotherapy is the only way to try and eliminate cancer, a recent report by Johns Hopkins is finally talking about some alternative methods.

1. It’s a fact that every person has cancer cells in the body. These cancer cells do not show up in the standard tests until they have multiplied to a few billion. When doctors tell cancer patients that there are no more cancer cells in their bodies after treatment, it just means the tests are unable to detect the cancer cells because they have not reached the detectable size.

2. Cancer cells occur between 6 to more than 10 times in a person’s lifetime.

3. When the person’s immune system is strong the cancer cells will be destroyed and prevented from multiplying and forming tumors.

4. When a person has cancer it indicates the person has multiple nutritional deficiencies. These could be due to genetic, environmental, food and lifestyle factors.

5. To overcome the multiple nutritional deficiencies, changing diet and including supplements will strengthen the immune system.

6. Chemotherapy involves poisoning the rapidly-growing cancer cells and also destroys rapidly-growing healthy cells in the bone marrow, gastrointestinal tract etc, and can cause organ damage, like liver, kidneys, heart, lungs etc.

7. Radiation while destroying cancer cells also burns, scars and damages healthy cells, tissues and organs.

8. Initial treatment with chemotherapy and radiation will often reduce tumor size. However prolonged use of chemotherapy and radiation do not result in more tumor destruction.

9. When the body has too much toxic burden from chemotherapy and radiation the immune system is either compromised or destroyed, hence the person can succumb to various kinds of infections and complications.10. Chemotherapy and radiation can cause cancer cells to mutate and become resistant and difficult to destroy. Surgery can also cause cancer cells to spread to other sites.

11. An effective way to battle cancer is to starve the cancer cells by not feeding it with the foods it needs to multiply.

Some people are okay with using tap water or soda pop to quench their thirst, the downsides to those are the facts that tap water generally contains contaminants and pop contains sugar and does nothing to improve the body.  Water filters give you the opportunity to drink tap water without the junk.  Here are some other reasons:
 
•  Water filters provide better tasting and better smelling drinking water by removing chlorine and bacterial contaminants.
•  Point-of-use water filters remove lead from drinking water immediately prior to consumption, thus preventing this harmful substance from entering the body.
•  The purchase of a countertop filter results in a source of clean, healthy water that costs much less than bottled water.
•  Water filters greatly reduce the risk of rectal cancer, colon cancer, and bladder cancer by removing chlorine and chlorine byproducts from drinking water.
•  A solid block carbon water filter can selectively remove dangerous contaminants from drinking water while retaining healthy mineral deposits that balance the pH of drinking water.
•  Drinking clean, filtered water protects the body from disease and leads to overall greater health.
•  A water filter provides clean, healthy water for cooking, as well as drinking, at the convenience of tap water.
•  Water filters reduce the risk of gastrointestinal disease by more than 33 percent by removing cryptosporidium and giardia from drinking water.
•  Drinking pure water is especially important for children. Water filters provide the healthiest water for children’s developing immune systems.
•  Water filters offer the last line of defense between the body and the over 2100 known toxins that may be present in drinking water.
