Sludge Dewatering for Water Treatment
Dryer cakes, clearer filtrate, lower disposal tonnage — charge-matched to your press.
Municipal water clarification
Polyaluminium ChlorideTurbidity and colour removed ahead of sand, carbon and membrane stages, with the dose set by jar test on the plant's raw water.
NSF/ANSI 60 listed coagulants and flocculants keep finished water inside permit while cutting backwash water and chemical spend.
Sludge dewatering
Polyacrylamide (PAM)Cake leaves the press dry, haulage volume falls, and filtrate returns clear enough for the head of the plant.
Cationic grades are charge-matched to the sludge and moved to the dilution point that actually mixes on belt, plate and screw presses.
Textile dyeing wastewater
Water decolouring agentReactive, disperse and sulphur dye colour removed at the source, before the discharge standard bites.
Decolouring agents and PolyDADMAC are dosed against the dyebath, cutting colour and COD without loading the biological stage.
Catalogue
Product-to-application matrix
Eleven products, three sectors. Every name is the name on the specification sheet — ask for the grade and we send the datasheet.
