Sunfloc Anionic Polyelectrolyte for Plating and Phosphating Effluent in Hosur
SIPCOT plants in Hosur run phosphating, electro-coating and plating. Sunfloc Anionic turns the zinc, nickel and phosphate precipitate into fast-settling flocs.
What the lines discharge
Hosur's vehicle and component plants operate pre-treatment, phosphating, e-coat and paint lines, while electronics plants contribute cleaning and plating rinses. Between them these streams hold zinc, nickel, phosphate, paint solids and surfactants.
Plants generally equalise first, then adjust pH so metals and phosphate precipitate, then coagulate, flocculate and clarify.

The polymer step
An anionic grade such as Anionic HQ turns the fine metal hydroxide and phosphate precipitate into fast-settling flocs. After the detackifier, a polymer also helps float or settle the paint-booth sludge so it can be skimmed and pressed.
Sizing example: 1,500 cubic metres a day, dosed at 1.5 mg/L, consumes 2.25 kg of polymer per day. Confirm the dose by jar test before ordering.
A next-day neighbour
Hosur is about 305 km from our Chennai stock along the national highway, and goods usually arrive the following day. Small, frequent orders keep polymer fresh in a plant where the dose barely moves. The Tamil Nadu Pollution Control Board regulates units here.
Anionic Sunfloc questions from Hosur
Does it work before the pH is corrected?
No. Correct the pH first so that the metals precipitate; the polymer then gathers the precipitate.
What about the paint-shop sludge?
After detackification, a polymer helps the sludge settle or float so that it can be removed.
Which pack should I buy?
Anionic HQ in 25 kg bags for daily use, Anionic MQ in 10 kg bags for smaller plants.
A worked example for a phosphating and electro-coating line
Take a phosphating and electro-coating line: 600 m³ a day at 0.8 mg/L is 0.48 kg of Sunfloc Anionic a day, about 14.4 kg a month. Made up at 0.1%, that is 480 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Zinc and nickel hydroxide settle better when pH is held steady, so confirm pH at the dosing point before you change the polymer dose.
