Anionic Polyelectrolyte Powder — ETP Flocculant, Vadodara

Anionic polyelectrolyte (Deoil Poly grade) from Drashti Chemicals breaks oil-in-water emulsions and stabilises floc in API, edible-oil, and metal-working effluent across Gujarat. Cationic polymers fail on oily wastewater — anionic charge targets positively charged oil droplets and metal hydroxide floc. Deoil Poly is the standard after DAF or API separator when effluent TSS and O&G still exceed GPCB consent.

High-MW anionic (18–20 million) for emulsion breaking; medium-MW for sludge dewatering after inorganic coagulant. Charge density 20–30% suits mixed oily effluent; higher charge for refinery and lubricant waste. Drashti matches Deoil Poly equivalent to your current import brand on request — send label photo. COA confirms charge density, viscosity, and dissolution time.

Make-down: 0.1–0.3% in soft water, 60-minute maturation. Dose 2–15 mg/L after ferric or alum coagulation — sequence matters: coagulant first, then anionic polymer. For DAF, dose at pressurisation tank inlet. Overdose re-emulsifies oil — if O&G rises after polymer increase, reduce dose immediately. Jar test with actual oily composite sample mandatory.

Packaging: 25 kg Kraft-lined bags (powder), 25 kg emulsion drums. MOQ 5 kg repack trial; bulk quote on request for API and engineering clusters in Vadodara and Ahmedabad. MSDS and COA per lot. GST 24AGLPC6288M1ZX. Store powder dry; emulsion above 5 °C.

Anionic vs. cationic polyelectrolyte: anionic for oily and positively charged colloid effluent; cationic for bio-sludge and anionic dye wastewater. Anionic vs. non-ionic: non-ionic for extreme pH. Pair Deoil Poly with ferric chloride on oily effluent — ferric breaks emulsion, anionic polymer builds settleable floc. Do not use cationic DWP on oil emulsion — it worsens stability.
