Our flocculants are specially designed for the treatment of various types of industrial wastewater, such as municipal or paper industry wastewater. When added into turbid water suspended with particles, flocculants neutralize the electric charges of polymeric particles suspended in the water and promote adsorption and bridging of these polymers. As result, rapid agglomeration and the sedimentation will occur, leading to faster separation and clarification of the wastewater, and thereby improve operating efficiency and reduce costs.

Flocculants are essential for solid-liquid separation in water treatment and industrial processes. Polyacrylamide (PAM)-based flocculants dominate due to their high efficiency, while inorganic coagulants remain cost-effective for some applications. Selection depends on water chemistry, sludge characteristics, and cost considerations.
