The efficiency of polyaluminum chloride and anionic ...
Nonionic polyacrylamide PAMN is a water-soluble polymer or polyelectrolyte. Because there are a certain number of polar groups in the molecular chain, it can bridge the particles by adsorbing suspended solid particles in water or coagulate particles to form large flocculants by neutralizing charges.

Get PriceWhat is a nonionic polymer (Pam)?
Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain. It can adsorb solid particles suspended in water and bridge between particles to form large floccules, accelerate the sedimentation of particles in suspension, accelerate the clarification of solution, and promote filtration.
What is anionic polyacrylamide (PAM)?
Anionic polyacrylamide (PAM) possesses interconnected and active groups that establish robust bonds with the surface of suspended colloids, promoting the formation of coarse particles among the suspended solids and a mixture of insoluble particles in water (Irfan et al. 2017).
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.
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.
Why is polyaluminum chloride acidic?
Why? We need to know the functions of PAC and PAM first. The aqueous solution of polyaluminum chloride is acidic, with a pH between 3.5-5.0, which can adjust the pH of the water quality. The applicable water pH range of polyaluminum chloride is between 3-12, which is wider than that of polyacrylamide.
What is polyaluminum chloride?
[English name] Polyaluminium Chloride, abbreviated PAC. [Technical standard] Product quality in line with national GB15892-2003 standard. Compared with other coagulants, polyaluminum chloride has the following advantages: wide application range, wide adaptability to water. Easy to quickly form large alum flower, good precipitation performance.
