Chennai The Central Leather Research Institute (CLRI), a constituent body of the Council of Scientific and Industrial Research (CSIR), has developed a technology that checks pollution due to effluents from leather units. The technology, called SRIOM (Salt Recovery from Inorganic and Organic Mixture), helps separate sodium chloride and calcium chloride contained in the evaporated residue of reverse osmosis (RO) rejects. These rejects contain a high degree of dissolved salts and organics that are harmful to earth and cannot be reused at the industrial level.
