Rice husk Ash (RHA) is a unique waste material which can be utilized to obtain valuable chemicals. This waste generated out of burning husk in Boilers, create huge pollution problem when dumped in open land or in water. Chemicals can be made by using such waste. The technology of converting RHA to sodium silicate is a novel process developed by us where in the process is a semicontinuous and operated on closed loop process. There is no liquid, gaseous pollution. The cake obtained after filtration is taken care of by removing the retained product and pure Activated Carbon, with slightly low activation can be obtained and sold as by-product for rice bran oil filtration and allied industries. We have two standard production line 10 MT per day 15 MT per day Major application of sodium silicate Soap, detergents, bar soap and cleaning compounds. Ceramics & binders. Adhesives & cements. Pulp and paper bleaching sizing, de-inking. Paper coating, paper tube winding. Textile bleaching, processing. Buffering agent. Concrete grouting. Soil solidification. Water treatment. Leather polishing. Welding electrodes. Paints & coatings. Mining & mineral processing. Chimney, furnace, refractory. Construction chemicals, damp- proofing.
