Nandesari Industrial Estate to commission treatment facilities for industrial effluents

Nandesari Industrial Estate in Vadodara will commission two treatment facilities for highly concentrated industrial effluents for the first time in the state. The technologies will meet the parameters set by pollution watchdog, which their predecessors were not capable of, claimed the planners.

The Rs 15 crore Electro Oxidation technology used for the Common Effluent Treatment Plant (CETP) will discharge water with Chemical Oxygen Demand (COD) at least one sixth of the conventional CETPs. For example the COD limit of Ammonical Nitrate will be reduced from 200 milligrams per litre to 20 mg/litre or even lower, while that of phenol will be reduced from 50-80 mg per litre to very miniscule quantities.

The new CETP plant with a capacity of 5.5 Million Litres per Day (MLD) will cater to the requirements of over 150 units in Nandesari producing chemicals, dye-stuffs, pesticides, pharma and textile products amongst others. ""The discharged water will have constituents well within the limit prescribed by 
Gujarat Pollution Control Board (GPCB) before it is discharged deep into the sea in Gulf of Khambhat. This will largely minimize the extent of pollution,"" said Babubhai Patel, president of Nandesari Industrial Estate.

Another facility to be introduced in the estate is the Common Plasma Incineration Facility for highly hazardous organic materials. The new Rs 20 crore facility will meet the demand for the quality of discharges and its residues will be used in the construction industry, claim users.

""We have got cooperation from Nagpur-based National Environment Engineering Research Institute (NEERI) for your unit which has a capacity of 10 tonnes. Similar incineration plant are there in Maharashtra, but they are funded by the government, while this is funded by industries. We feel that there is huge potential for similar treatment plants in rest of the state,"" said 
Mohan Nair, MD of Nandesari Environment Control Limited, the specialized body for management of the CETP in the estate.

Gujarat has a share of close to 500 MLD of effluent treatment in the nationwide capacity of 1,065 MLD. Local authorities feel that with the adaptation of modern technology, there is an improvement in scenario of controlling pollution. ""In 2-3 years, we have seen that industrial estates are coming up with modern technologies for treatment of industrial effluents. With this there is a sustainable improvement on pollution control front. The momentum will continue. We are also providing financial assistance for setting up such effluent treatment plants,"" said 
Hardik Shah, member secretary of Gujarat Pollution Control Board.
