Nonionic Polyacrylamide NPAM 20-100 Mesh 89% Min Solid for Latex and Rubber Wastewater Clarification

Product overview

Latex and rubber wastewater may contain stable dispersed particles, surfactants and fine coagulated material. The composition depends on the production process and the cleaning streams entering treatment. A stable dispersion may not respond to a low-charge flocculant alone, even when the product is fully dissolved.

NPAM is considered for particle bridging after suitable destabilization or where the solids already have a favorable surface condition. Selection should establish whether the process first needs pH adjustment, a compatible coagulant or another emulsion treatment. The chosen sequence is then tested for clarification and sludge handling.

Technical data

Application process

Characterize the latex dispersion and establish a baseline. Test the required destabilization chemistry and process pH before introducing NPAM. Prepare the polymer separately, add it after initial coagulation where appropriate and use gentle floc growth conditions. Compare settling or flotation according to the plant separator, then assess the resulting sludge.

Grade and dosage selection

Compare NPAM with other charge types where the latex chemistry makes that relevant. A weak response can indicate inadequate destabilization rather than insufficient NPAM dose. Record surfactants, conductivity, cleaning chemicals and any natural versus synthetic rubber stream differences. Use representative mixing conditions so that fragile flocs are not selected on appearance alone.

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.
