How water filters work - 1: Review the filter and activated carbon filters

Water filters are essentially of a material that absorbs pollutants amended and made traps in the water. The substance in the filters, the medium is known. filter media for many species can be easily found, some of them work with mechanical trapping pollutants using an ultra-fine screen, while other types of media to use the absorption process. The process involves mainly the absorption of pollutants in the water in microscopic pores ofthe medium.

Water Filter

The rating of a filter for the water basically says that size of foreign bodies from the water filter and the size will not. Water filters are typically rated micron (one millionth of a meter) or micrometers. There are basically two kinds of subtleties;

Nominal Filtration: This type of assessment also shows the smallest particle size of the filter should eliminate or reduce in connection with the design of the filter criteria. However,This is an estimated value and not an exact value. For example, a 5 micron rated filter must always be the case for 95% of all particles 5 microns or larger.
absolute filtration: This type of filtering basically refers to a rate reduction certificates, which is usually 99.9%. Therefore, a 5 micron absolute filtration substantially eliminate 99.9% of particles 5 microns or more in diameter.

Activated carbon filters

This type of filterparticularly helpful in removing pollutants that create an unpleasant smell, taste and color in water. The activated carbon filters made of various organic materials such as coal, wood, coconut shell and coal. When these substances are at high temperature in the absence of oxygen leads to a substance that contains millions of microscopic pores exposed to a wide area. About one pound of activated carbon offers more than 50 hectares, with an incredibleable to absorb small organic molecules. The fast carbon filters to remove the power and reduce the levels of chlorine byproducts, herbicides, pesticides and other industrial chemicals and organic. There are basically two forms of activated carbon in these filters;

Granular carbon: carbon granules about the same size of a grain of coarse sand.
Carbon Block: Block C is essentially a finely powdered charcoal, compressed into a solidified isMass. For maximum efficiency of the activated carbon filter must be kept clean and free of any heavy sediment and organic contaminants. This can be done with the introduction of a sediment filter as part of the design of the filter. It 'important that the activated carbon filter cartridges should be replaced periodically, before they reach their maturity date, rather than elapsed after the expiration date.
