Sunfloc Cationic Polyelectrolyte for Dyeing and Tannery Sludge in Erode
Dyeing units and Perundurai tanneries both produce sludge that cationic polyacrylamide (PAM) conditions, and floc that it settles in the CETP.
Two industries, one polymer family
Erode's yarn and fabric processors produce coloured, alkaline effluent, and the tanneries in the Perundurai estate produce protein, fat, lime, sulphide and chromium. Both end up with the same kind of problem after treatment: a sludge that has to be dewatered before disposal.
Cationic HQ helps a filter press give up its water, so less weight goes out for disposal.

Tannery flocs
Chrome-bearing streams are usually segregated and treated for chrome recovery. The combined effluent is clarified with a cationic grade after coagulation, gathering protein and fat into flocs that settle.
Sizing example: 1,500 cubic metres a day, dosed at 4 mg/L, consumes 6 kg of polymer per day. Your own dose comes from a jar test.
Common plants
A common plant takes effluent from many small units at once, and the mix keeps changing, so its operator does well to test the equalised stream more often than a lone factory needs to. Erode is about 400 km from our Chennai stock through Salem, close enough for small, frequent orders. See also SunDec for Erode.
A worked example for a dyeing unit feeding a common plant
Take a dyeing unit feeding a common plant: 600 m³ a day at 1.5 mg/L is 0.9 kg of Sunfloc Cationic a day, about 27 kg a month. Made up at 0.1%, that is 900 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Members of a common plant send different effluent each day. Test on the combined inflow, not on one member's sample.
Cationic Sunfloc questions from Erode
Does cationic work for both dye house and tannery sludge?
Both are organic sludges, which cationic grades condition well. Doses differ, so test each.
Is MQ enough for a tannery?
A larger tannery usually prefers HQ; MQ suits smaller units.
How long is delivery?
One to two days by road.
