89% Minimum Solid Content Cationic Polyacrylamide CPAM with 2-Year Shelf Life for Garment Washing ETP Sludge Conditioning

Product overview

A garment washing ETP may combine sludge from coagulation, flotation and biological treatment. Fabric fibers, finishing chemicals and detergents can vary by customer order and shift. Stable polymer preparation and controlled sludge blending are therefore as important as the nominal product specification.

Blufloc CPAM is used to evaluate whether cationic conditioning can improve aggregation and water release before thickening or dewatering. The selected charge and molecular weight should reflect the actual blend entering the machine. Minimum solid content supports product quality control, but it does not define the optimum plant dosage.

Product benefits

Technical data

Application process

Identify which ETP sludge streams enter the conditioning tank and whether their proportions change during the day. Prepare the CPAM solution separately, verify complete dissolution and meter it to the mixed sludge feed. Compare grades at equivalent product dosage and dry-solids loading. Confirm the selected condition during both regular production and cleaning-related load changes.

Grade and dosage selection

Select charge by the response of the real sludge rather than by the garment industry label alone. A chemically dominated sludge may need a different grade from a biological sludge. For big-bag use, confirm that the unloading station, dry feeder and make-up capacity suit the site consumption. Keep the unopened powder dry; shelf life does not describe the usable life of a prepared solution.

Performance evaluation

Solution preparation

Prepare a 0.1–0.5% solution by mass using clean water. Add powder gradually to moving water to avoid lumps. Allow around one hour for dissolution, adjusting for grade, water quality and temperature. The TDS gives 200–400 rpm as a mixing reference; adapt mixing to the actual tank and impeller. Avoid unnecessary high shear after dissolution. A 0.1% solution contains 1 kg of product per 1,000 kg of final solution. Select the treatment dose separately through controlled trials.

Packaging storage and handling

Featured packaging is a 750 kg net big bag. Store the dry product sealed at 0–35 °C, protected from moisture and direct sunlight. The stated shelf life is two years under specified storage conditions. Reseal opened packaging and follow the current SDS for handling and spill cleanup.
