What is polyaluminum chloride (PAC)?

Received 2nd November 2021 , Accepted 26th November 2021 Polyaluminum chloride (PAC) is an inorganic polymer material that has the advantages of a simple preparation process and special electronic structure. It is considered to be the most efficient and widely used flocculation material for water treatment.

How effective is coagulant & flocculant?

Results showed that the most effective impact of coagulant and flocculant was the treated wastewater in Jar 5 using only 16 mg/L of PAC and 0.04 mg/L of PAM were used as coagulant and flocculant, respectively, resulting the value of the turbidity, pH, COD, BOD, and TSS was 2.00 NTU, pH 6.22, 2.00 mg/L, 5.22 mg/L, and 2.00 mg/L, respectively.

What is the most effective dosage for polyaluminum chloride (PAC) & aluminum sulfate (FEC?

The findings revealed that the most effective dosages for polyaluminum chloride (PAC), aluminum sulfate (Al 2 (SO 4) 3), and ferric chloride (FeCl 3) were 20, 10, and 20 mg/L, respectively.

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).

Do PAC materials have different morphological characteristics in different solvents?

The results show that the PAC materials have different morphological characteristics in different solvents. The Al–O–Al cations were transformed in the ethanol solvent to form new multi-nuclear cation aggregates Al b, which could be used as inorganic micro–nano reactors with unique synergistic catalysis in catalytic reactions.

Can PAC materials be used in non-aqueous solvents?

The stability and exceptional catalytic performance of PAC materials in non-aqueous solvents (ethanol) may provide unlimited possibilities for their applications in the field of organic synthesis.
