Filtration Aids

The flocs formed when alum or PAC are used as coagulants for raw water treatment, are weak in nature, fluffy and have high moisture content. When some of these flocs carry over along with the clarified supernatant on to the sand bed filter, the flocks break up and clog the flow channels resulting in frequent backwashes. On use of Rishlyte for the treatment of raw water, the flocs formed are stronger and compact and add to the filter bed, thereby increasing the clarity of filtered water. These flocs do not break nor clog the filter, thus improving efficiency of filtration and increasing the filter run. Increase in filter run upto 3 to 4 times have been observed, resulting in huge savings of water, labour and electricity.
