Polyferric Sulfate for Phosphorus Removal: What to Check Before a Plant Trial
Tight effluent phosphorus limits are one of the most common reasons wastewater plants revisit chemical treatment. When biological removal alone cannot hold total phosphorus (TP) at the required limit, operators usually turn to a metal salt — and polyferric sulfate (PFS) is one of the iron-based coagulants frequently considered, alongside ferric chloride and ferrous sulfate. PFS is attractive because it is a pre-polymerized iron salt that can precipitate orthophosphate, improve floc settling,...
How to Select Polyacrylamide for Sludge Dewatering Trials
Selecting polyacrylamide (PAM) for sludge dewatering requires more than choosing a polymer charge or comparing a price per kilogram. Use representative sludge, documented product preparation and a staged trial to compare candidates against your current process. 1. Describe the Sludge and Equipment Record the sludge source, current blend, available analysis and machine type, such as a belt press, centrifuge or screw press. Include the existing polymer grade, preparation arrangement and operating...
Jar Test Procedure for PAC, PFS and PAM in Wastewater Treatment
A jar test is a bench-scale comparison of candidate chemicals and operating conditions. For PAC, PFS and PAM, define the water, product and process conditions before comparing results. A successful jar result is a screening result, not an automatic plant dose or a compliance guarantee. Equipment and samples Use suitable jar-test equipment, equal sample volumes and appropriate measuring instruments. Record the vessel volume, paddle configuration, sample source, collection time, holding...
How to Select a Coagulant for Industrial Wastewater: PAC vs PFS vs PAFC
How to Select a Coagulant for Industrial Wastewater: PAC vs PFS vs PAFC Selecting the right coagulant for industrial wastewater is a technical decision that affects turbidity removal, sludge volume, operating cost and the stability of every downstream treatment step. Polyaluminium chloride (PAC), polyferric sulfate (PFS) and polyaluminium ferric chloride (PAFC) are three of the most common options on the market, and the difference between them is not simply "which is stronger" — it is which...

The Flocculation Performance of Polymeric Ferric Sulfate
In the field of wastewater treatment, polymeric ferric sulfate (PFS), as an advanced iron-based flocculant, exhibits excellent clarification efficiency, pollutant removal capacity, and system stability. When polymeric ferric sulfate is dosed into a wastewater treatment system, it rapidly interacts with suspended impurities in the water. The polymerized iron ions contained in PFS can effectively neutralize the surface charges of suspended particles, thereby eliminating the electrostatic...
