Leather units get access to new pollution control technology

Salt Recovery from Inorganic and Organic Mixture (SRIOM), a technique to check pollution caused by the effluents discharged by the leather units, has been developed by the Central Leather Research Institute (CLRI), a body constituted under the Council of Scientific and Industrial Research (CSIR).

The technique helps in segregating sodium chloride and calcium chloride, which are a part of the evaporated waste from the reverse osmosis (RO) process. A high level of organics and dissolved salts are found in this waste which is hazardous to earth and is even not possible to reutilise the same at the industrial level.

The new technique is a single stage fragmentation process. Till date, no reports regarding recovery of sodium and other chlorides from the evaporated wastes of RO rejects stream with high concentration of organic salts have been found.

Apart from helping the leather industry attain zero liquid discharge (ZLD), the new technology also enables utilization of the salt with high purity content as edible salt and also in chemical and pharmaceutical industries.

Indian patent was granted to SRIOM technology in 2010. As per the current data, high level of total dissolved solids (TDS) and dissolved organics like BOD5 and COD are found even in processed liquid effluents of the tanneries. Thus, the secondary biological processed liquid effluents need to undergo membrane separation process for recovering water in the presence of inorganic salts and refractory organics.

As the pilot tests of the technology have remained positive, it is soon likely to be introduced at cluster level and then on a larger scale.

CLRI has urged the Centre to attach substantial importance and effectively push the SRIOM technology in the 12th Five Year Plan and also to extend necessary financial support.

CLRI or CSIR are entitled to further provide licence for use of SRIOM technology in leather clusters in the country, while not parting with the patent rights.
