Polyacrylamide

1. Water and wastewater treatment flocculant: Polyacrylamide is widely used as a primary flocculant to aggregate suspended solids, enhance settling and increase clarifier throughput in municipal and industrial wastewater treatment. Anionic grades are effective for removing colloidal and particulate matter, improving effluent clarity and reducing turbidity. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
2. Sludge dewatering and filter press performance: high-molecular-weight polyacrylamides aid cake formation and improve dewatering on belt presses and filter presses. They reduce cake moisture, speed solids capture and lower polymer consumption when the appropriate charge density and molecular weight are selected for the sludge type. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
3. Enhanced oil recovery and drilling fluids: polyacrylamide-based polymers (including partially hydrolyzed variants) increase water viscosity and mobility control in tertiary oil recovery operations. In drilling fluids, they serve as viscosity modifiers and shale stabilizers, enhancing borehole stability and cuttings transport. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
4. Mineral processing and flotation aids: polyacrylamide is used for flocculation of tailings, thickening and recovery operations in mineral processing. It improves settling rates, consolidates fine gangue particles and can assist in water recycling by enabling clearer overflow for reuse. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
5. Paper and board industry and dewatering: as a retention and drainage aid in papermaking, polyacrylamide increases retention of fines and fillers, improves sheet formation and accelerates dewatering on the wire section. Appropriate cationic or anionic selection is critical to match furnish chemistry. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
6. Industrial process viscosity and rheology control: polyacrylamide functions as a rheology modifier and thickener in a variety of formulations (paints, adhesives, cosmetics and agricultural products). KieRay Chem provides guidance on selecting ionic type and molecular weight to optimize performance and minimize overdosage, backed by COA and handling recommendations. It also helps users improve process consistency, manage production risk, and maintain predictable results across scale-up, routine manufacturing, and finished-product quality checks for Polyacrylamide (CAS 9003-05-8).
