Sodium hydroxide is an inorganic compound with strong alkalinity and strong corrosiveness. It can be used as an acid neutralizer, coordination masking agent, precipitant, precipitation masking agent, colorant, saponification agent, peeler, detergent, etc. It has a wide range of uses.

Sodium hypochlorite is an inorganic compound mainly used in many fields such as bleaching, industrial wastewater treatment, papermaking, textiles, pharmaceuticals, fine chemicals, hygiene and disinfection.

Polyaluminum chloride can adsorb particles in water, used for flocculation and sedimentation in wastewater treatment, and can also be used as a filter aid.

Iron trichloride is an important water treatment agent, which is an efficient and inexpensive flocculant for the treatment of urban and industrial wastewater. It has significant effects on precipitation of heavy metals and sulfides, decolorization, deodorization, oil removal, sterilization, phosphorus removal, and reduction of effluent COD and BOD.

Ferrous sulfate is used for flocculation and purification of water, as well as for removing phosphates from urban and industrial wastewater to prevent eutrophication of water bodies. It can also serve as a reducing agent to reduce chromates in cement.

Polyacrylamide, as a flocculant, functions to contract and compress the corresponding double layer of colloidal particles, forcing them to reach a stable state and ultimately achieving centralized sedimentation.
