Polyelectrolyte for the sugar industry
Sugar mills run seasonally and hard, and their effluent plants have to keep up during crushing. Anionic polyacrylamide is the workhorse flocculant in this industry.
Sunfloc Anionic HQ for regular plant use, or Anionic MQ for smaller plants and trials. Distillery streams usually need a cationic grade. Confirm on your own sample with a free jar test.
Mill effluent
Anionic polyacrylamide is the usual choice for sugar mill wastewater after coagulation. Start with Anionic HQ or Anionic MQ.
Juice clarification
Sugar juice clarification in the industry also uses anionic polyacrylamide. Talk to us about grade suitability before using any grade in a process stream.
Distillery and attached units
Distillery and brewing wastewater, rich in organics, usually responds better to a cationic grade. See Cationic HQ or Cationic MQ.
Season planning
Order ahead of crushing so stock is on site. In-stock grades dispatch from Chennai in as little as one business day.

Juice, wash water and effluent
Sugar mills use polymers at more than one point. In juice clarification, the suspended matter is mainly negatively charged, which is why anionic polymers are standard; SASRI describes this, and published work has tested acrylamide-based anionic flocculants on industrial cane juice. In wash water and effluent clarification, anionic polymer settles the solids; in the sludge stage, a cationic grade may suit better.
The season is short, so plan the order before crushing starts and keep sealed bags dry between runs. Test again at the start of each season, since cane quality changes the dose.
Dose carefully: more is not better. An over-dose can leave the overflow cloudy, which is why the jar test is repeated in the first week of the season.
