Polyelectrolyte for textile and dye effluent
Dyeing, printing and processing units send effluent loaded with colour, size, fibre and fine solids. Sunfloc finishes the clarification step so solids settle and the clarifier overflow stays clear.
Sunfloc Cationic HQ for regular plant use, or Cationic MQ for smaller plants and trials. Pair it with SunDec SC05 for colour. Confirm on your own sample with a free jar test.
Where the polymer goes
After the coagulant and any colour-removal stage, at a point with gentle mixing just before the clarifier or flotation unit.
Which charge
Cationic polyacrylamide is the usual choice for textile and dyeing wastewater. Start with Cationic HQ or Cationic MQ, and compare an anionic grade in the jar test if your plant uses heavy metal-salt coagulation.
Colour
A flocculant settles solids; it does not remove dissolved dye. For colour, pair it with a decolorant such as SunDec SC05.
Sludge
Textile ETP sludge is usually dewatered with a cationic grade too. See sludge dewatering.
