Do Water Filters Work?

Water filters are specialized sieves used to ensure that water is clean and safe for drinking. With water being vital to the survival of humanity, the use of water filtration systems is of great importance. Unfiltered water carries with it sediment and microorganisms that may be harmful to ones health. This makes the increasing of a filtration theory in the home of great value.

There are separate types of water filters available commercially that intend to serve the same purpose - making water safe for use. These filters use discrete processes such as distillation, reverse osmosis and carbon bonding.

The distillation process involves boiling the impure water until it vaporizes leaving any particles in it behind. The vapor then passes through a gismo that cools it back to liquid form. This process, tested in laboratories using an apparatus known as a distillation tank, has proven quite effective.

Reverse osmosis is a more involved process. The water molecules, which are under great pressure force their way through a thin film or membrane. The membrane blocks substances in the water from seeping through. Reverse osmosis has proven sufficient in removing heavy metals such as lead and aluminum from water as well as microorganisms like bacteria and viruses.

Systems that use carbon in the filtration process work through adsorption. The carbon filtration process is composed of two determined procedures, chemical bonding and mechanical straining.

In Chemical Bonding, an activated piece of black charcoal, which is hydrophorbic, is used. The black charcoal has an electro-positive fee that makes it a more provocative bonding agent to chemicals and other impurities. As water soldiery its way through the carbon, it passes slowly to allow enough caress time. This enables sediment in the water to attach to the carbon.

The second formula of water purification using carbon is mechanical straining; carbon compressed into a solid block is used. Water molecules strain through the carbon blocks miniature pores and effectively eliminate any particles. This formula is more sufficient in removing a larger amount of contaminants than chemical bonding because it has larger outside area of carbon.

The degree of effectiveness will depend on the flow rate of water and the caress time with the carbon. If the flow rate is too high, the filtration could have zero efficiency. These carbon filtration methods are more sufficient in removing sediment, chlorine, and organic compounds from water. They are not as sufficient in removing dissolved inorganic compounds, minerals or salts.

These filtration systems have all proven to eliminate harmful organisms from water to a determined extent. Although water filter manufacturers claim that their products eliminate all impurities in water, the truth is that no filter is 100 percent effective. Human error as well as malfunction of the filtration theory is possible.

When purchasing water filters, it is important to take note of the filtration process they use. Most citizen prefer those that couple distillation while others prefer a compound of any processes. Water filters are sufficient means of purifying water.
