20-100 Mesh Off-White Granular Powder Anionic Polyacrylamide APAM for Textile Printing and Dyeing Effluent Clarification

Product overview

Printing and dyeing wastewater may contain fibers, dispersed pigments, dye-associated colloids and variable amounts of salts and surfactants. Different fractions respond to different treatment stages. Capturing suspended particles does not necessarily remove dissolved dyes or all dissolved organic material.

Blufloc APAM is evaluated as a flocculant that bridges particles and existing microflocs into larger aggregates. Its role is to help the clarification system separate destabilized solids. Depending on the wastewater, a compatible coagulant or water decoloring agent may be needed before APAM produces a useful settling response.

Product benefits

Technical data

Application process

Begin with equalized wastewater and establish the effective coagulation and pH conditions. Add a fully dissolved APAM solution after the main coagulation reaction, then use gentle mixing to grow flocs. Compare settling tests with the existing treatment and an untreated control. For flotation systems, assess bubble attachment and floated sludge behavior instead of assuming that faster settling is the correct target.

Grade and dosage selection

A trial sequence may include BWD-01 for color-bearing wastewater, PAC for coagulation, pH adjustment where needed, and APAM for flocculation. The order must be verified with the actual effluent. High conductivity, changing dye recipes and excess upstream chemicals can alter polymer demand. Select a stable operating window rather than the single dose that produces the largest beaker floc.

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 25 kg kraft paper bag with an inner plastic liner. 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.
