Polyaluminium ferric chloride is an inorganic polymer coagulant developed on the basis of the coagulation and hydrolysis mechanism of aluminium salt and iron salt. It is a new type of high-quality coagulant prepared by adding elemental iron ions or ferric oxide and other iron-containing compounds based on the principle of synergistic enhancement. It combines the advantages of aluminium salt and iron salt, significantly improves the form of aluminium ions and iron ions, and greatly improves the degree of polymerization. Taking the advantages of aluminium and iron coagulants in flotation operation, the coagulation performance of polyaluminium chloride is improved; the purification effect of high turbidity water and low-temperature and low-turbidity water is particularly obvious, and no alkaline additives or other coagulants are added. Polyaluminium ferric chloride has a wide range of applications: it is used in drinking water, industrial water, domestic water, domestic sewage and industrial sewage treatment. Polyaluminium ferric chloride has a significant effect on the purification of drinking water and various industrial water. Polyaluminium ferric chloride is an inorganic composite pulp coagulant with a new structure formed by the composite copolymerization of aluminium salt and iron salt. It can take the advantages of aluminium salt and iron salt to a certain extent, and integrate the advantages of aluminium salt and iron salt flocculants. It is a good substitute for polyaluminium chloride and polyferric, making the initial coagulation time, floc size and sedimentation rate better than polyaluminium chloride, and the chromaticity of the effluent is better than ferric chloride, so that the efficacy can be better exerted and the raw materials can be reasonably utilized. It is in the form of yellow-brown or brown-red powder solid, easily soluble in water, with strong adsorption and bridging properties, and the aqueous solution is slightly acidic and easy to deliquesce in the air.

1. The flocs are formed quickly, the alum flowers are dense, the sedimentation effect is good, and the adsorption is high.
2. The pH range is wide, and the pH value is best at 4-10.
3. Small dosage, good effect, and cost saving.
