Sand, Activated Carbon, Multimedia and Greensand Media – choice of a filter depends upon the quality and source of water. Ideally for river water filters are placed after clarifier. For deep well water, as the suspended solids are much lesser compared to river water one can design system with filters as pre – treatment without clarifiers.  Sand Filter and multimedia filter are used for removing traces of TSS while activated carbon filter is used to remove color and organics. Green sand media filter is chosen when Fe and Mn are higher in the raw water.

Water softeners are used to remove total hardness from filtered water. Soft water has a tendency to avoid corrosion in boilers, cooling systems and pipes. Softening process is an ionic process which used strong acid resins for removing total hardness partially/completely from clarified water.

Demineralizing is an ionic process used in industry to remove dissolved impurities from filtered water. This process ensures complete removal of ions thus making filtered water suitable as boiler feed water, even for high pressure boilers.
For the media, we recommend Kowa Carbon, Lewattit Ion Exchange Resins, Tokhemy Anthracite, Ferrolite (Japan), Manganese Greensand, Alamo Zeolite, and Sand Silica (Bangka). Please contact us for your media needs.
