Anionic Polyacrylamide APAM 2-Year Shelf Life 89% Min Solid for Corn Starch Process Water Clarification CAS 9003-05-8 ISO 9001 Manufacturer 750kg Net Big Bag

Product overview

Corn processing water streams may contain fine starch, protein-associated solids, fiber and other material. Their suitability for polymer-assisted clarification depends on where they arise and where the separated water goes next. Process water, food production streams and final wastewater should be identified separately during selection.

APAM can be screened for aggregation of compatible suspended particles after existing physical separation or suitable coagulation. It is not a replacement for primary starch and protein separation equipment. If treated water or solids return to production, the exact grade and intended use must be confirmed before routine addition.

Product benefits

Technical data

Application process

Map the selected water stream and any return to production. Establish baseline suspended solids, temperature and pH. Following any required use review, prepare APAM separately and test it at the proposed process point. Validate separation at the available residence time and examine whether the resulting liquid meets the needs of its next process step.

Grade and dosage selection

Check conductivity, solids composition and any cleaning-related changes that enter the stream. Compare grades without assuming that all corn starch plant waters share one optimum. For 750 kg supply, confirm unloading, humidity control and make-up capacity. The two-year shelf life concerns dry powder stored as directed; prepared solution requires separate age and quality management.

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 750 kg net big bag. 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.
