Sunfloc Anionic Polyelectrolyte for Vaigai Raw Water in Madurai
Vaigai raw water swings from clear to turbid with the river. A small anionic polyacrylamide (PAM) dose after alum or PAC keeps Madurai clarifiers steady.
A worked example for a small municipal water plant
Take a small municipal water plant: 500 m³ a day at 0.2 mg/L is 0.1 kg of Sunfloc Anionic a day, about 3 kg a month. Made up at 0.1%, that is 100 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Flood and drought want different doses from the same river. Keep a short log of raw turbidity against the dose that worked.
City water from the Vaigai
Vaigai dam water changes through the year, fairly clear and low in the dry months and turbid once rain sends the river down. Treatment plants coagulate with alum or PAC and then add a little anionic polymer, Anionic MQ or HQ.

A daily test in flood, a weekly one in drought
Because raw water quality changes, the right dose changes too. Testing daily while the river runs, and weekly in the dry months, keeps the clarifier steady and the polymer bill down.
If the plant treats 3,000 m³ daily at 0.4 mg/L, the polymer bill is 1.2 kg a day and the make-up tank turns over 1,200 litres at 0.1%.
Small plants make it up by hand
Where a small plant mixes by hand, sprinkle granules slowly through a wetting funnel or eductor, stir gently for 45 to 60 minutes, and finish the batch within a day. Madurai is about 460 km from our Chennai stock and a consignment usually lands in one to two days. The Tamil Nadu Pollution Control Board regulates units.
