Sunfloc Anionic Polyelectrolyte for Pharma Fenton Sludge in Hyderabad
After Fenton oxidation, pharma units around Hyderabad must settle iron hydroxide sludge. Anionic polyacrylamide (PAM) speeds it up and compacts it.
High-strength streams and Fenton
Bulk drug effluent changes with every campaign. Strong streams in the Patancheru, Jeedimetla and Bollaram clusters are often stripped of solvents and then sent for evaporation or advanced oxidation such as Fenton treatment.
Fenton runs acidic. Once the stream is neutralised, iron precipitates as a fine sludge that must settle before the water moves on.

Where the anionic grade earns its place
Iron hydroxide sludge is mineral, so an anionic grade such as Anionic HQ is the usual starting point; a cationic grade is worth comparing in the jar test. With polymer the sludge settles and compacts, so much less of it travels on to the next stage. Our guide on settling sludge after Fenton sets out the sequence.
One day's use at 300 m³ and 2 mg/L is 0.6 kg; at 0.1% that works out near 25 L/h of solution through the dosing pump. Your own dose comes from a jar test.
Records and supply
Pharma plants face frequent audits from regulators and customers, so record the dose and the batch for every polymer. The Telangana Pollution Control Board regulates units, and road freight from Chennai usually takes about two days; plan orders around campaigns so the plant is never short mid-run.
A worked example for a pharma unit after Fenton oxidation
Take a pharma unit after Fenton oxidation: 150 m³ a day at 1.2 mg/L is 0.18 kg of Sunfloc Anionic a day, about 5.4 kg a month. Made up at 0.1%, that is 180 litres of solution a day. These figures are illustrative; a jar test on your own effluent sets the real dose.
Neutralise before dosing: the iron hydroxide floc forms after pH is raised, and it is that floc the anionic grade bridges.
Anionic Sunfloc questions from Hyderabad
Why not use a cationic grade after Fenton?
Iron hydroxide is a mineral sludge, where an anionic grade is the usual start. Compare both in a jar test.
Does it help the downstream RO?
A cleaner clarifier overflow means fewer solids reach the membranes.
How long is delivery?
About two days by road.
