India Sand Washing Wastewater Case | Anionic PAM Flocculation Test by Hengfeng Project Background Recently, Jiangsu Hengfeng Fine Chemical conducted a laboratory flocculation test using a batch of sand washing wastewater samples brought back from India. Sand washing operations generate wastewater ...

A medium-to-large copper concentrator recently optimized its tailings thickening circuit to improve solid-liquid separation efficiency, increase water recovery, and raise underflow density. Shortly after changes in ore characteristics (finer grind and higher clay content), the high-rate thickener ...

Characteristics of Industrial Circulating Water and the Application of Polyacrylamide in Its Treatment Industrial circulating water is water that is repeatedly used in a closed or semi-closed loop, typically for cooling, heating, or process purposes. Its main characteristics include: Cyclic reuse: ...

Recently, through professional and repeated laboratory tests, Jiangsu Hengfeng Fine Chemical Co., Ltd. has achieved groundbreaking results in vessel bunker wastewater treatment with its optimized flocculant formula. The product exhibits excellent and stable treatment performance in laboratory ...

A large sand‑washing plant located in Minas Gerais, Brazil, was confronted with inefficient solid‑liquid separation for mineral‑rich wastewater. The raw wastewater contained massive fine quartz particles, clay and silt fractions. The previously adopted polymer produced fragile flocs, slow sedimentat...

Polyacrylamide (abbreviated as PAM, CAS No. 9003-05-8) is a water-soluble linear high-molecular polymer formed by free radical polymerization of acrylamide monomers, with the molecular formula of (C₃H₅NO)ₙ. It is applied in different industry due to its character. It plays the following main roles ...

A large slaughterhouse wastewater treatment plant in Paraná, Brazil, was experiencing poor sludge dewatering due to the high concentrations of proteins, fats, and organic matter in its biological sludge. The existing polymer resulted in high sludge moisture, long filtration cycles, and increasing ...

The Application of Polyacrylamide in High-Salinity Wastewater Treatment‌ In high-salinity wastewater treatment, polyacrylamide (PAM) is primarily used as a ‌flocculant‌ during the pretreatment and sludge dewatering stages — not for directly removing salinity. The high-salt environment can significan...
