Delhi NCR industrial ETPs and STPs: a guide
How industrial areas, auto plants and the large sewage plants of Delhi NCR treat wastewater before it reaches the Yamuna, and which polymer suits each job.
A river under pressure
The Yamuna through Delhi carries far more wastewater than clean flow for much of the year, which is why regulators focus closely on industrial effluent and sewage treatment across the capital region.
Industrial areas and CETPs
Delhi's industrial areas, such as Okhla, Bawana and Narela, have many small units that send effluent to common effluent plants. Mixed, variable inflow is clarified with a coagulant and a cationic grade such as Sunfloc Cationic HQ.
Auto and engineering belts
Plants at Gurugram, Manesar and Faridabad run phosphating, plating and painting lines. After pH correction, an anionic grade such as Sunfloc Anionic HQ gathers the metal hydroxide and phosphate precipitate into fast-settling flocs.
Sewage plants and sludge
Large sewage plants produce primary and biological sludge that must be thickened and dewatered. Cationic polymer conditions the sludge ahead of centrifuges and belt presses; measure the dose per tonne of dry solids.
Several regulators
Units in Delhi answer to the Delhi Pollution Control Committee, while those in the Haryana and Uttar Pradesh parts of NCR answer to their state boards. Check which consent conditions apply to your site.
Supply
Road freight from Chennai usually takes five to six days. Order with a margin of stock, especially before the monsoon.
