Sunfloc Cationic Polyelectrolyte for Dye ZLD and Sludge in Tiruppur
After the decolorant has bound the dye, cationic polyacrylamide (PAM) builds the floc that settles it and conditions Tiruppur's dyeing sludge.
A worked example for the flocculation step behind SunDec in a dye ZLD plant
Take the flocculation step behind SunDec in a dye ZLD plant: 2,500 m³ a day at 2.0 mg/L is 5 kg of Sunfloc Cationic a day, about 150 kg a month. Made up at 0.1%, that is 5,000 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
The floc is built from decolorised solids, so a change in dye mix can need a new dose. Re-run the jar test then.
The flocculant step in a ZLD plant
In a Tiruppur dyeing plant the sequence is screening and equalisation, pH correction, coagulation, a decolorant, then a flocculant. Cationic Sunfloc is that flocculant: it gathers the coagulated and decolorised solids into large flocs that settle quickly in the primary clarifier.
A clean primary overflow matters more under zero liquid discharge than anywhere, because every particle that escapes ends up on filters, RO membranes and evaporators.

Sludge as the second job
The same chemistry conditions the sludge before dewatering. Cationic HQ in a 25 kg bag suits plants that press every day; Cationic MQ in a 10 kg bag suits smaller dye houses. Overdosing shows as slimy, slow-filtering sludge, so trim the dose rather than raise it when the press slows.
Take 2,400 m³ a day at 3 mg/L: that is 7.2 kg of polymer daily, and at 0.1% about 7,200 litres of solution. The dosing calculator on this site shows typical ranges.
Pairing with SunDec
Dose the decolorant first, then the flocculant. Colour removal is covered on SunDec for Tiruppur. Tiruppur is about 455 km from our Chennai stock and a consignment usually lands in one to two days. The Tamil Nadu Pollution Control Board sets your consent conditions; the Tiruppur ZLD guide covers the full train.
Cationic Sunfloc questions from Tiruppur
HQ or MQ for a mid-sized dye house?
HQ if you press daily and want the full specification for an audit file; MQ for a smaller plant that uses a bag over several weeks.
What does overdosing look like?
Slimy, slow-filtering sludge and fouled filters.
Can I test both charges?
Yes. Send a litre from the equalisation tank and we test both.
