Cationic Polyacrylamide CPAM Off-White Granular Powder 20-100 Mesh for Leather Tannery Sludge Dewatering CAS 9003-05-8 ISO 9001 Manufacturer 25kg PE Bag

Product overview

Leather processing produces different wastewater streams from soaking, liming, tanning and finishing. Sludge may contain proteins, fats, precipitated chemicals and biological solids. Chromium-bearing sludge, where present, should be evaluated within the plant's designated collection and treatment system rather than treated as an interchangeable organic sludge.

Blufloc CPAM can help compatible fine solids form water-releasing flocs before a press or centrifuge. Its function is sludge conditioning. Polymer treatment does not by itself remove dissolved chromium from wastewater or change the classification of a contaminated sludge. Those questions depend on the upstream treatment and the resulting analysis.

Product benefits

Technical data

Application process

Identify the sludge source and complete the required upstream treatment before polymer screening. Collect representative thickened sludge and prepare CPAM separately. Compare grades using drainage and floc-strength observations, then meter the selected solution into the conditioning stage. Verify performance after normal pumping and transfer, particularly where a plate-and-frame press requires a permeable cake structure.

Grade and dosage selection

Check pH, conductivity, solids content and residual coagulants. High salt content and changing chemical sludge proportions can alter the best charge level. Where different tannery sludge streams are blended, test the normal blend and likely extremes. Select on dewatering performance at comparable loading rather than on powder color or floc appearance alone.

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 PE 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.
