Description/ Specification of Activated Carbon Filter
Activated carbon filters find application in water treatment system. Their basic purpose is to remove free chlorine and organic impurities from water. The presence of organic acids in water may cause the chlorine to react and form carcinogenic compounds like Trihalomethanes. The carbon used is activated before placing it inside the filter. The process of activation opens the pores thereby increasing the surface area that takes part in a process called adsorption which takes away the undesirable impurities mentioned earlier. The activation process may be either steam activation or chemical activation. Steam activation is carried out using steam at temp as high as1000 degree centigrade. It gives activated carbon media with a high pore structure. Chemical activation process uses chemical reaction at high temperature (500-800 Degree C) to activate the carbon and produced filter media suitable for adsorbing large molecules. ACFs has low operating cost and are very effective for pre-treatment of water used in DM Plant and RO Plant. The effectiveness of ACF depends on a number of factors such as media pore size and distribution, source of the carbon (coal/lignite/coconut shell), process used for activation, type of contaminant and it’s concentration, time allowed for activation, water temperature and PH. So, the filter design has to take care of all these factors. This page list the companies who have long experience in design, manufacture, installation, and after sales support of activated carbon filters.
