With a view to overcome the challenges of salinity, sulphide oxidation in the effluent, disposal of hazardous category sludge & other environmental issues faced by tanning industries in the world leather sector improved cleaner production, segregation of saline soak liquor and separate treatment, modified chrome recovery system and recovery of chromium & sodium chloride salt in the form of powder and quality water with TDS less than 500mg/l for reuse by tanneries have been developed and are being implemented in the cluster of tanneries with Common Effluent Treatment Plants (CETPs). Physiochemical treatment is converted into total biological treatment with sulphide oxidation using enzyme and biomass which resulted in major reduction in terms of volatile organic matter and overall 50% sludge generation from the effluent treatment plant.
