Cationic Polyacrylamide CPAM 5-12 Million MW 89% Min Solid for Brewery Wastewater Sludge Dewatering CAS 9003-05-8 ISO 9001 Manufacturer 25kg Kraft Paper Bag

Product overview

Brewery wastewater treatment sludge can vary with fermentation losses, cleaning operations, upstream flotation and the biological treatment system. Waste activated sludge, anaerobic sludge and chemically separated material may dewater differently. Their source and blend must be identified before comparing polymers.

CPAM supports aggregation of compatible organic sludge into flocs that can retain solids and release water during mechanical dewatering. The preferred molecular weight is the one that performs under the machine's mixing and separation conditions. A higher value within the family range does not by itself guarantee a drier cake.

Technical data

Application process

Take a representative sample from the sludge feed used by the dewatering machine. Record the contribution from biological and flotation sludge where they are blended. Prepare CPAM separately and compare grades at controlled dose and feed solids. Confirm the selected condition during normal production and after cleaning-related wastewater loads have passed through treatment.

Grade and dosage selection

Screen charge and molecular weight together. Biological sludge structure, digestion and residual coagulants can change the optimum. Use drainage screening for initial comparison, followed by a trial on the intended screw press, belt press or centrifuge. Keep polymer solution age, make-up water and mixing consistent so that preparation differences do not distort the comparison.

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.
