It is used for effective removal of color, odor, organic contamination and chlorine in water. The activated carbon also removes certain chemicals that are dissolved in water passing through a filter containing GAC by trapping the chemical in the GAC. However, other chemicals, like sodium or nitrate, are not attracted to the carbon and are not removed.
Activated carbon filters are made from mild steel/FRP closed vessel incorporating frontal piping fitted with valves and are operated under pressure. The water is passed through the under bed media & granular activated carbon layer. Where the carbon granule at certain level absorbs unwanted impurities for removal of free chlorine, phenol, taste and odor as well as reduction COD/BOD etc.
Carbon filter have back flushing arrangement, which very easily flushes away the deposited impurity at carbon granules. Thus the reverse flow of water flushes away the impurities deposited at carbon granules.
Activated Carbon Filter, for removal of free chlorine, phenol, taste and odor as well as reduction in COD/BOD.

Filtration is the process of passing liquid containing suspended matter through a suitable porous material (filtering medium) to effectively remove the suspended impurities in the liquid. It is the final step in the solid removal process which includes coagulation, Flocculation and sedimentation.
Types of Filters
* Inline filtration – In this process coagulant chemicals are added just prior to the water entering the filtration unit.
* Conventional filtration – It is a process commonly employed in municipal and large water treatments. Here all the pretreatment steps are included
* Direct filtration - It is similar to conventional filtration except that the step of sedimentation is omitted.
Materials used as filter media
Quartz sand, Silica sand, Anthracite. |
