The difference between polyferric sulfate and ferric sulfate

PFS means polymeric ferric sulfate. Ferric sulfate is also a water-treatment coagulant, including for wastewater treatment; it should not be dismissed as mainly a non-water-treatment reagent. Product names alone do not establish which option will work better for a particular plant.

Use Representative Trials

Record the water sample, tested dose, operating conditions and treatment targets. Measure the indicators required by the project, rather than assuming universal removal of phosphorus, sulfur, COD or suspended solids.

Compare total treatment cost, including chemical consumption, separation and sludge handling, not just the purchase price. A wider usable operating range or better performance must be demonstrated for the specific products and water being tested.

Ask Lanyao for Product Information

Provide the wastewater analysis, current process and target indicators. Request the proposed grade specification, batch COA, SDS and sample availability before procurement. Drinking-water applications require grade-specific suitability and supporting documentation.
