Anionic Polyacrylamide APAM 0.1-0.5% Working Solution for Potato Starch Wastewater Solids Recovery CAS 9003-05-8 ISO 9001 Manufacturer 25kg PE Bag

Product overview

Potato starch wastewater can include granule losses, fine fiber and other organic suspended matter. Its composition depends on the sampled process stage and the separation already installed. A stream collected after primary starch recovery may have a different polymer response from mixed washing water or final combined effluent.

A compatible APAM grade can aggregate fine suspended particles into separable flocs. The objective may be lower solids loading to downstream treatment, improved handling of captured material or recovery for a defined industrial use. The captured fraction should not automatically be marketed as pure starch or as a suitable food or feed ingredient.

Technical data

Application process

Sample the selected stream consistently and measure suspended solids before treatment. Review whether primary screens or separators can recover useful material before chemical addition. Prepare APAM solution, add it to the remaining fine-solids stream and compare sedimentation or flotation as appropriate. Test the captured material for its intended destination and assess the remaining liquid's treatment needs.

Grade and dosage selection

The make-up solution range of 0.1–0.5% does not prescribe a wastewater dosage. Select charge and molecular weight using the actual fine-solids mixture, then determine a dose response at the site conditions. If polymer-treated solids will enter food or feed, obtain specific use confirmation before trials intended for production recovery.

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.
