Polyacrylamide in the Sand-Washing Industry: Features and Applications

At Jiangsu Hengfeng Fine Chemical Co., Ltd., we specialize in producing high-quality polyacrylamide (PAM), a versatile water treatment chemical widely used in the sand-washing industry. Its unique properties make it an essential component for improving efficiency, water quality, and sustainability in sand-washing operations.
Key Features of Polyacrylamide for Sand Washing
Strong Flocculating Capability
Polyacrylamide is highly effective at flocculating fine particles such as silt, clay, and organic matter. This property helps in quickly aggregating suspended solids, allowing them to settle and be easily removed from the water used in sand washing.
Water-Saving Benefits
One of the biggest advantages of using polyacrylamide is its ability to improve water recycling. By settling out fine particles more effectively, PAM allows for clearer water to be reused in the washing process, reducing the overall water consumption.

High Efficiency in Sedimentation
The high molecular weight of polyacrylamide ensures rapid sedimentation, reducing the time needed for clarification and allowing sand-washing plants to operate more efficiently. This results in faster processing and reduced downtime.
Applications of Polyacrylamide in Sand Washing
Fine Particle Flocculation
During the sand-washing process, fine particles like clay and silt remain suspended in the water. Polyacrylamide is added to the slurry, causing these particles to bind together and form larger aggregates, which then settle at the bottom, leaving the water clearer for reuse.
Clarification of Effluent Water
After the washing cycle, wastewater containing suspended solids is treated with polyacrylamide to separate the solids from the liquid. This allows for cleaner effluent discharge or the reuse of treated water in the washing process, reducing environmental impact and improving water management.
Sludge Dewatering
The flocculated particles from the sand-washing process are easier to separate and dewater. PAM aids in forming compact sludge, which can be more easily handled and disposed of, or reused if needed.
At Jiangsu Hengfeng Fine Chemical Co., Ltd., we are committed to providing top-quality polyacrylamide products that improve efficiency, reduce water usage, and support sustainable practices in the sand-washing industry.
