Anionic Polyacrylamide APAM pH 6-8 in 1% Solution for Starch Recovery from Process Water CAS 9003-05-8 ISO 9001 Manufacturer 25kg Kraft Paper Bag

Product overview

Starch-bearing process water may carry fine granules that escape screening or other physical separation. Collecting these fines can reduce the solids load sent to wastewater treatment. However, the recovered material may also contain fiber, protein or other suspended matter, so recovery should not be described as purification without analysis.

APAM assists aggregation of compatible suspended particles so that they can be separated by the selected process. It does not recover dissolved carbohydrates merely by making the water look clear. If solids or water are to re-enter food or feed production, confirm the specific polymer's suitability for that return path before dosing.

Technical data

Application process

Identify a starch-bearing stream after the existing primary recovery steps. Measure its solids and confirm the intended destination of recovered material. Prepare APAM separately, test several suitable grades and compare separation at the available residence time. Where process return is proposed, complete the grade-specific use review and verify the recovered material's quality before any production return.

Grade and dosage selection

The pH 6–8 specification is measured on a 1% product solution; it is not an instruction to set every starch recovery stream to that pH. Select the treatment conditions from granule stability, process compatibility and trials. Avoid unnecessary heating or chemistry changes during screening that could alter starch behavior and make the result unrepresentative.

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.
