Import Cw-05 — Buy in Bulk from Supplier in China

CW-05 is a liquid cationic resin-based decoloring agent used primarily in wastewater treatment for textile, printing, and paper industries. It appears as a light-colored liquid with a solid content of 50%, a specific gravity of 1.1 to 1.3 at 20°C, and a pH of 1.5 to 3.0 when diluted to a 30% solution. The viscosity ranges from 5 to 50 cps at 25°C, and it is fully soluble in water regardless of dilution rate.

This chemical functions as both a decolorizing flocculant and a retention aid in papermaking. It promotes rapid sedimentation of colored dyes and suspended solids, reducing sludge volume compared to inorganic coagulants like aluminum sulfate. The resin structure enables charge neutralization and bridging, enhancing floc formation. It is not compatible with polyaluminum chloride and must be dosed separately in the treatment sequence.

CW-05 is purchased by wastewater treatment plants serving dyeing mills, ink manufacturers, and paper production facilities. It is typically diluted 10 to 40 times before dosing into effluent streams, with optimal performance achieved at pH 6 to 10. The product is packaged in 30kg, 250kg, or 1250kg drums and stored at ambient temperature. Buyers should confirm dosage rates through jar testing before full-scale implementation.
