Anionic Polyacrylamide APAM 5-25 Million MW 89% Min Solid for Carpet Dyeing Wastewater Flocculation CAS 9003-05-8 ISO 9001 Manufacturer 25kg Kraft Paper Bag

Product overview

Carpet dyeing and associated washing operations can generate wastewater with fibers, dispersed color, auxiliaries and variable suspended matter. Where backing or coating operations also discharge to the same treatment system, latex-associated solids may add another separation challenge. Representative sampling must reflect the streams actually entering the plant.

APAM can bridge destabilized particles after suitable pretreatment. The desired flocs should separate effectively in the existing clarifier or flotation unit while producing manageable sludge. Dissolved dye removal may require BWD-01 or another compatible treatment stage, depending on the dye chemistry and the required effluent quality.

Technical data

Application process

Screen coarse fibers and equalize the wastewater where required. Establish coagulant, decoloring and pH conditions before testing APAM. Dose the fully dissolved polymer after initial particle destabilization, then reduce mixing intensity for floc growth. Compare both separation performance and the ease of removing the resulting sludge under the actual plant residence time.

Grade and dosage selection

Higher molecular weight can change bridging behavior, solution viscosity and sensitivity to mixing. The best grade depends on particle size, anionic degree, upstream chemistry and shear. Test more than one point within the 5–25 million family range. If the wastewater contains latex or stable emulsions, assess the destabilization step before increasing APAM dosage.

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.
