Why is polyaluminum chloride a good coagulant for water treatment?

Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .

Can Pam be used for sludge dewatering?

PAM can be used for sludge dewatering; In industrial water treatment, mainly used as a formula. In the raw water In treatment, using organic flocculant PAM instead of inorganic flocculant, the water purification capacity can be increased by more than 20% even if the sedimentation tank is not reformed.

What is the application of Pam in water treatment industry?

1 water treatment field :PAM in the water treatment industry application mainly includes raw water treatment, sewage treatment and industrial water treatment three aspects. In raw water treatment,PAM and activated carbon used together, can be used for coagulation and clarification of suspended particles in living water; In sewage treatment.

Is polyaluminium chloride a safe coagulant?

Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.

How to use polyaluminum chloride?

Usage :1. Dissolve solid polyaluminum chloride into liquid by adding 1:3 water, and then dilute it with 10-30 times water to the required concentration before use. 2, dosage can be determined according to the different turbidity of raw water, the best dosage, generally raw water turbidity in 100-500mg/L, each thousand tons of dosage is 10-20kg.

Can PAC be used as coagulant for water treatment?

The ZPD value of PAC was also revealed that the flocculation tendency of PAC particles was very high in water, and the PAC could be used as coagulant for water treatment. Fig. 5.
