Sunfloc Anionic Polyelectrolyte for Monsoon Raw Water in Thiruvananthapuram
Karamana raw water can turn from clear to turbid in hours, twice a year. Anionic polyacrylamide (PAM) after the coagulant keeps the clarifier steady.
A worked example for a raw-water plant between two monsoons
Take a raw-water plant between two monsoons: 1,500 m³ a day at 0.2 mg/L is 0.3 kg of Sunfloc Anionic a day, about 9 kg a month. Made up at 0.1%, that is 300 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Humidity cakes open bags, so reseal the bag after every use and store it off the floor.
Two monsoons
Both the south-west and north-east monsoons bring rain to the state capital, and the Karamana river and its dams can go from clear to very turbid within hours. Water works operators are rarely idle.

Dosing through heavy rain
Clarifiers use a coagulant followed by a small dose of an anionic polymer such as Anionic MQ or Anionic HQ. In heavy rain, test several times a day and move the dose in small steps as turbidity climbs and drops.
One day's use at 4,000 m³ and 0.5 mg/L is 2 kg; at 0.1% that works out near 83 L/h of solution through the dosing pump. Confirm the dose by jar test before ordering.
Humidity and storage
Humid air cakes an opened polymer bag fast. Reseal after each use, keep bags off the floor, and buy a size that the plant finishes within a few weeks. Road freight from Chennai via Madurai and Tirunelveli usually takes two to three days, and the Kerala State Pollution Control Board regulates units.
