SIPCOT & SIDCO PHASE II ENTERPRENEUR FINISHED LEATHER EFFLUENT TREATMENT CO. (P) LTD (SIDCO Phase II)

Ranipet is an industrial town about 120 km from Chennai (Madras) on Chennai-Bangalore national highway. It is an important tannery cluster. There are more than 200 tanneries operating in and around Ranipet town. Apart from the tanneries there are many downstream leather product industrial units, including shoe, garment and leather goods factories. The total annual turnover of the leather industrial sector from this cluster is of the order of Rs. 1000 crores. Of this, export accounts for about 45%. More importantly, Ranipet cluster is an important source of supply of leather to downstream industries all over the country. Many leather product manufacturers procure raw material elsewhere and get the same tanned and finished in the Ranipet cluster.

The Common Effluent Treatment Plant is managed by SIPCOT & SIDCO Phase II Entrepreneur Finished Leather Effluent Treatment Company Pvt. Ltd., in short SIDCO-II CETP, a company formed by 40 tanners who are its members. This company is registered under the Indian Companies Act and managed by a BoD, drawn from its members. Mr. R. Srinivasaraghavan, a tanner of the area, is currently the Managing Director of the company.

Project Components

The ZLD system proposed in SIDCO-I1 CETP consists of the following:

  1. CETP upgrading: new mechanical screen, modification of equalizations tank with new mixing system, new mechanisms and bridges for primary & secondary clarifiers, mechanical sludge dewatering, softening to remove hardness and improvement in monitoring.
  2. RO system: Pre-treatment filtration, organic scavenger, ultra-filtration, two stage reverse osmosis and automated control system for the same.
  3. Mechanical Evaporation of RO reject: Five effect evaporation with thermal vapour re-compression system and pusher centrifuge for separation of salts.
  4. Salt disposal yard: special disposal unit to store generated salt for two years at full capacity.
  5. Recovered water conveyance system: overhead tank and piping system with metering for conveying the recovered water back to individual tanneries. Individual tanneries are providing individual storage tanks with more than one day storage capacity.

The turnkey implementation of the project was awarded to Hyderabad based Ramky Infrastructure Ltd based on a two stage competitive tendering. The contract value is Rs. 16.5 crores and the total project cost including administrative charges is Rs. 17.3 Crores.
