The pollutants of Tannery to treat and dispose is BCS and Lime! Stop using these.... the hazardous waste does not exist... Hence treatment becomes much easier!
EcoTan Process (TANNERY TREATMENT) : The virulence of the Tannery Effluents can be substantially reduced (by nearly 70%) by simply replacing Basic Chrome Sulphate (BCS) with ECOTAN, a proprietary organic reagent developed by us, which has been tested and approved by the Central Leather Research Institute (CLRI), Chennai (Patent applied).
Powder Lime or Calcium oxide used in the liming process leaves behind a sludge that is hard to dispose off. The high degree of sludge produced in Tanneries can be substantially reduced by replacing the Powder Lime used in the process with ECOLIME, a sludge-free, eco-friendly liquid substitute, also developed by us. Patent has been applied for.
The resultant, relatively benign tannery effluents can be further purified in Effluent Treatment Plants (ETP's) and treated with small doses of ECOCLEAN-20 and ECOCLEAN-50, which will neutralize most of the other salts and toxins in the effluent water. This treated water can then be safely discharged or reused for General Purpose.
