Research and testing

Polymer recommendations supported by laboratory comparison

Polyacrylamide performance depends on charge demand, molecular weight, pH, salinity, suspended solids, mixing energy and the downstream separation equipment. Xinqi’s laboratory evaluates candidate grades against measurable treatment results rather than relying only on catalog names.

Typical checks include floc formation, settling speed, supernatant clarity, filtrate quality, cake moisture and dose response.
