Cationic Polyelectrolyte Supplier — SunFloc Cationic
SunFloc Cationic is our own Sun Brand cationic polyelectrolyte (cationic polyacrylamide), manufactured by Suraj Chemicals in two grades — HQ and MQ — with a downloadable specification sheet and MSDS for each. Supplied from Chennai with pan-India dispatch.
What is a cationic polyelectrolyte?
A cationic polyelectrolyte is a water-soluble polymer that carries a positive charge along its chain. SunFloc Cationic is a cationic polyacrylamide (CAS 9003-05-8) supplied as a white granular solid.
Most suspended and colloidal matter in water and wastewater — organic matter, biological solids, fibres — carries a negative surface charge. A cationic polyelectrolyte neutralises that charge, and its long chains bridge the destabilised particles into larger flocs that settle, float or dewater more easily.

Where cationic polyelectrolyte is used
Effluent treatment & sludge
Flocculation in effluent treatment plants and conditioning of sludge before thickening or dewatering equipment.
Municipal & industrial water
Clarification of raw water and process water where the solids carry a negative charge.
Paper industry
Paper and pulp mill applications, including treatment of mill effluent.
Textile & mineral processing
Textile effluent treatment and mineral processing, as listed on the SunFloc product sheets.
Choosing and dosing
The right polymer and dose depend on your water or sludge. Run a jar test with the SunFloc Cationic grade before plant use — we can help you plan it.

Frequently asked questions
What is a cationic polyelectrolyte used for?
A cationic polyelectrolyte is a flocculant: it gathers fine suspended particles into larger flocs so they settle, float or dewater. It suits negatively charged, largely organic solids such as biological sludge.
What is the difference between cationic and anionic polyelectrolyte?
Cationic polyelectrolytes carry a positive charge and are generally chosen for negatively charged, organic solids; anionic polyelectrolytes carry a negative charge and are generally chosen for inorganic solids and coagulated metal-hydroxide flocs. A jar test on your own water or sludge is the reliable way to choose.
Which SunFloc Cationic grade should I choose, HQ or MQ?
Both are cationic polyacrylamide in granular form. The HQ grade comes with an extended specification (molecular weight, charge density, viscosity, residual acrylamide and dissolution data); the MQ grade is specified on core parameters. Share your application and we will suggest a grade for a jar test.
How do I prepare a polyelectrolyte solution?
Disperse the granules slowly into the vortex of gently stirred water to avoid lumps, then keep stirring until fully dissolved. For SunFloc Cationic HQ the specification sheet gives a recommended working concentration of 4 g/L, a dissolution time of about 90 minutes at 5 g/L, and a solution stability of 1 day. Dilute further for dosing as your plant requires.
Who manufactures SunFloc Cationic?
SunFloc Cationic is manufactured by Suraj Chemicals, Chennai, and sold under our own trademarked Sun Brand.
