Sunfloc Anionic Polyelectrolyte for Turbid Raw Water in Kochi
Periyar raw water around Kochi can turn many times more turbid in a day of monsoon rain. Anionic polyacrylamide (PAM) keeps the clarifier ahead of it.
A worked example for a raw-water works in monsoon
Take a raw-water works in monsoon: 3,000 m³ a day at 0.15 mg/L is 0.45 kg of Sunfloc Anionic a day, about 13.5 kg a month. Made up at 0.1%, that is 450 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Raw-water turbidity can change within a day of heavy rain, so keep a jar-test kit at the intake and test twice a day in the monsoon.
Turbidity that doubles in a day
Kochi receives very heavy south-west monsoon rain, and raw water turbidity from the Periyar can rise many times in a day. Operators of water works and industrial raw-water plants run a jar test every day in the monsoon and move the anionic dose (Anionic HQ, for example) with turbidity.

The Eloor–Edayar belt
Chemical and fertiliser plants at Eloor and Edayar produce inorganic effluent. Once pH is corrected and the coagulant is in, an anionic grade brings the precipitate down and the sludge goes to the press.
At 5,000 m³/day and 0.4 mg/L the arithmetic gives 2 kg of polymer a day; made up at 1 g/L the pump moves roughly 83 L/h. Your own dose comes from a jar test.
Before the monsoon
Road freight via Salem, Coimbatore, Palakkad and Thrissur takes about two days from Chennai, and delays are likelier when the rains break, so place larger orders ahead of the season. The Kerala State Pollution Control Board regulates units. For the seafood plants, see cationic polyelectrolyte for Kochi.
Anionic Sunfloc questions from Kochi
How often should I jar-test in the monsoon?
Daily, and more often on days of heavy rain.
Is the dose linear with turbidity?
No. Use jar tests and move the dose in steps.
How long is delivery?
About two days by road.
