Carbon water filter - an explanation of how

The most common filter aid in water filters, including those used in refrigerators and coal. Coal has the capacity to absorb pollutants, removing them from the water as the water flows to the coal (adsorption medium on a surface in a thin layer of stick in contrast to absorb soak). The use of filtering mechanisms activated carbon is an effective method for removal of chlorine (and its derivatives) and volatile organic compounds such as atrazine,Benzene, radon, PCBs and toluene, along with many others.

There are two main types of activated carbon used for water filtration. Granular activated carbon (GAC) and the solid carbon block (CB). Activated Carbon is very porous and has large areas of water law can be cleaned. It 'hard to imagine, but at the microscopic level, many cracks and pores of activated carbon, exposing the surface of the coal. To give you an idea of ​​this surface is aTeaspoon of activated charcoal has a surface the size of a football field. In addition, activated carbon has added a slight positive electrical charge attracts the negative ions on the surface contaminants have made of carbon as a magnet, remove the water.

Water Filter

The effectiveness of the GAC, depending on how slow the flow through the carbon and water until the surfaces in contact with carbon. Of course, as long as water remains in the charcoal filter, whichThe higher the filtration and vice versa. The trick is the exposure time, so that water flows through the charcoal filter out just long enough to do without it for so long that the consumer is becoming impatient.

Another effective method to filter water through a solid carbon block (CB) of types of carbon mixed with plastic polymers can be mixed and then molded under pressure. The CB filters are given a contrast filter GAC filtration. Water takes longer to move between the blocks of carbongranules do not absorb carbon as carbon blocks, and so was able to eliminate impurities from the GAC as a filter. A 1 / 2 microns CB can significantly reduce asbestos and cysts, although not completely eliminate them from the water.

Water filters should be changed regularly according to manufacturer's recommendations. In the case of refrigerator water filters should be changed at least every six months for optimal performance. The filters are designed to purify a specificNumber of gallons of water. However, you do not want to use a water filter refrigerator for more than six months to see if the amount indicated was drawn through the filter into the water, because bacteria builds carbon in the filter, and after six months, able to establish amount of bacteria to increase to dangerous levels. Even if not, change the water filter every six months, the filter is saturated with contaminants and bacteria and the clogged filter canthen lose unwanted impurities in the recycled water.
