Gradiant India, a subsidiary of Boston-based Gradiant Corporation, has signed a contract with the Ambattur Industrial Estate Manufacturer’s Association (AIDMA) and Chennai Auto Ancillary Industrial Infrastructure Upgradation Company (CAAIIUC) to develop and install a common effluent treatment plant (CETP) for the Ambattur industrial cluster.

The land for the proposed CETP has been provided by the Tamil Nadu Small Industries Development Corporation. CETP is set to treat 2,00,000 ltr of effluent per day on a design, build, own and operate (DBOO) basis.

The facility will be owned, operated and maintained by Gradiant India for a minimum period of 15 years, ensuring a complete asset management philosophy. Furthermore, the plant will recover high quality treated water for reuse by industries, thereby reducing their freshwater intake and overall cost of treatment.

The trade effluents from metal processing industries contain a high amount of total dissolved solids and require robust systems to handle the same.
