Cationic Polyacrylamide CPAM 5-80% Charge Degree for Distillery Wastewater Sludge Conditioning CAS 9003-05-8 ISO 9001 Manufacturer 25kg PE Bag

Product overview

Distillery wastewater treatment can produce biological, digested and chemically separated sludge, depending on the plant process. Feedstock, fermentation losses and treatment configuration affect the solids. Concentrated stillage or vinasse is not automatically equivalent to the sludge sent to mechanical dewatering.

CPAM can assist charge interactions and bridging in compatible sludge, helping particles form a structure suitable for water release. The most useful charge level balances conditioning with solids capture and drainage. A high cationic degree is not automatically the best choice for every organic sludge.

Product benefits

Technical data

Application process

Identify the material being treated and distinguish raw process residues from wastewater sludge. Record solids content, digestion history and any upstream coagulants. Prepare CPAM separately, compare several suitable charge levels and test a dose response. Introduce the selected matured solution at a point that gives uniform conditioning before the dewatering equipment.

Grade and dosage selection

Use the 5–80% cationic charge range as a screening framework. Compare grades at a consistent solids concentration and realistic shear. If drainage worsens at higher dose, investigate overdosing, incomplete dissolution and sludge changes before increasing charge further. Where sludge is hot, test representative temperature conditions and confirm the grade's suitability rather than inferring heat tolerance from powder storage data.

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.
