Get Price- Can polyaluminum chloride be used in water treatment?
- In this study, synthesis and speciation of polyaluminum chloride (PAC) for application in water treatment was investigated using a colorimetric speciation method. It was possible to produce stable preparations of PAC solutions in which a relatively stable cationic polymer predominated.
- What is alupac – poly Aluminium chloride?
- (PAC) Poly Aluminium Chloride – AluPAC is a high purity product with high aluminum content. AluPAC is produced according to EN 883 (Chemicals used for the treatment of water intended for human consumption). AluPAC neutralizes the colloidal charge whereby compact flocks are formed.
- 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 [ 6 ].
- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
