New Delhi: Delhi Jal Board has started trial run of the 20 MGD Waste Water Treatment Plant at Pappankalan, which will benefit around nine lakh people apart from helping reduce pollution in the Yamuna river.
"DJB is in the process of commissioning the newly constructed 20 MGD (Million Gallons per Day) Waste Water Treatment Plant that has been constructed at an estimated cost of Rs 243 crore," said a senior official of DJB.
About 9 lakh people living in different areas of Uttam Nagar, Dwarka, Palam and Bijwasan Assembly constituencies will benefit with the commissioning of the plant as sewerage facility will reach them contributing to improved hygienic condition there, he said.
Commissioning of the plant will ensure treatment of all waste water before it flows into the drain and only treated effluent is discharged into the Yamuna thus contributing towards abatement of pollution in it.
Based on advanced technology, the plant functions on high rate clarifier with combined biologically flooded filters. These filters have an environment friendly smaller footprint, the officer said.
It is based on activated sludge process with tertiary treatment. Both, the Biological Oxygen Demand and total suspended solids will be less than 10 mg/litre.
The bio-gas generated by the plant will meet 50 per cent of its power demand. It will trap sewage from Palam and TD-II drain before they join Najafgarh drain and treating sewage before discharging it into the Najafgarh drain, he said.
At present, the plant is commissioned for treatment of sewage. Its other units for sludge digestion, power generation and conversion of sludge into manure will be commissioned by December, 2015, the official added.
