Industrial water-treatment polymers, backed by SNF
Suraj Chemicals is an authorized distributor for SNF, the world's largest producer of water-soluble polymers for water treatment. Below are the SNF anionic and cationic polyelectrolyte flocculants, coagulants and dispersants we currently supply, verified against genuine SNF certificates of analysis and technical data sheets. In line with SNF's confidentiality requirements, products are listed by their chemistry (ionic character, molecular weight, physical form) rather than SNF's internal grade codes.
Every product listed here is a genuine SNF-branded product, supplied through us as an authorized SNF channel partner.
Cationic Polyelectrolytes & Coagulants
Positively charged grades for charge-neutralizing negatively charged solids — biological/mixed sludge, industrial effluent.
White granular solid
White granular solid
Anionic Polyelectrolytes & Dispersants
Negatively charged grades for raw-water clarification, mineral-processing settling and process-water dispersant duty.
White to off-white free-flowing powder
White granular solid
Clear and colourless to yellow liquid
Clear and colourless to yellow liquid
Nonionic Polymers
We don't currently hold nonionic SNF grades in stock, so we won't list one here just to fill the category — but as an authorized SNF channel partner we can source and quote a nonionic polyelectrolyte for raw-water clarification or other low-charge-demand duty on request, same traceability and documentation as our stocked grades.
Flocculants
Dry, free-flowing powder/granular flocculation aids — dissolved on site into a working solution.
White to off-white free-flowing powder
White granular solid

Sludge-Dewatering Grades
Every SNF grade below has mechanical dewatering (belt press / centrifuge / filter press) as a documented, listed application — matched to your equipment and sludge type.
White to off-white free-flowing powder
Listed application: sludge dewatering (belt press / centrifuge conditioning).
White granular solid
Listed application: dewatering of alkaline / mineral-processing sludges; belt press, centrifuge and filter press.
White granular solid
Listed application: biological, mixed and primary sludge dewatering; digested sludge on belt press / centrifuge.
White granular solid
Listed application: municipal and industrial sludge dewatering — two viscosity grades for different equipment.
Clear and colourless to yellow liquid
Listed application: high-viscosity anionic dispersant for sludge dewatering and paper-pulp applications.
Clear liquid
Listed application: sludge dewatering conditioner ahead of belt press / centrifuge.
Application guidance
A general starting point by duty — always confirm with jar testing on your actual water/sludge before dosing at scale. Our team can help you run that comparison.
| Raw water / drinking water clarification | Anionic or high-MW grades as a flocculation aid after a primary coagulant (e.g. PAC, alum, ferric chloride). |
| Effluent / biological & mixed sludge (ETP) | Cationic, high-to-very-high molecular weight — charge-neutralizes negatively charged biological solids. |
| Mechanical sludge dewatering (belt press, centrifuge, filter press) | Cationic granular or liquid grades, matched to your equipment — see Sludge-Dewatering Grades below. |
| Mineral processing / mining tailings | Anionic, ultra-high molecular weight (e.g. red mud, alumina residue settling). |
| Process water, cooling water & RO/membrane systems | Liquid anionic dispersants — antiscalant / dispersant duty, reduces fouling in high-solids streams. |
| Paper industry | Both ionic characters in use — cationic/anionic polyelectrolytes for retention & drainage, liquid dispersants for pulp applications. |
