Activated Carbon Filter Reduces odour, colour, smell & for De chlorination.
The principal media in these filters is activated carbon. Other supporting media include pebbles of various sizes, crushed gravel and silex. The activated carbon is a highly porous media. This property of carbon allows it to adsorb the free chlorine in raw water. Also organic matter present in colloidal form is adsorbed in these pores. Thus odour emanating from raw water on account of these colloids is reduced. The activated carbon present in the standard range has an iodine value of 450. This carbon is also available in iodine values of 600, 900 and 1200.
