Cationic Polyacrylamide CPAM pH 4-6 in 1% Solution for Dairy Effluent Sludge Dewatering in 25kg Kraft Paper Bag

Product overview

Dairy wastewater systems can produce fat- and protein-rich flotation sludge, biological sludge or a mixture of both. Cleaning-in-place operations may influence the wastewater entering treatment, while production changes affect the quantity and composition of captured solids. These differences should be represented in the polymer trial.

CPAM can support floc formation and water release in compatible dairy sludge. Performance depends on charge, molecular weight, mixing and the condition of the solids. Selecting the product by its 1% solution pH alone would overlook the factors that determine drainage and solids retention.

Technical data

Application process

Sample the sludge from the actual feed tank and document any blending. Prepare CPAM solution separately using consistent make-up water. Compare suitable grades and doses, then test the selected condition on the operating press or centrifuge. Include a representative production cycle so that a favorable result is not based only on an unusually easy sludge sample.

Grade and dosage selection

Check sludge solids, pH, fat content and residual coagulants. If feed conditions change after cleaning events, address equalization and blending as well as polymer selection. The pH 4–6 specification refers to a 1% polymer solution and does not require acidification of dairy sludge. Evaluate sludge pH changes only where the process and trials justify them.

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.
