Effect of polyaluminium chloride water treatment sludge
The results obtained showed a decrease in total suspended solids (TSS), chemical oxygen demand (COD), total ammonium nitrogen (TAN), and total phosphates (TP) in the supernatant after 30 min of settlement. The optimal PA-WTS dosage of 37.5 mL/L significantly (P<0.05) increased the TSS, TP and

phosphate and fluoride are also removed. Polyaluminium chloride is found to be more effective towards suspended solids (SS), COD, phosphate and fluoride removal, when compared to other coagulants used in the present study. Addition of an anionic polyelectrolyte (Magnafloc 156) to PAC improved the performance

Aluminium Coagulant
There are some coagulants, such as polyaluminium chloride (PACl), aluminium chlorohydrate (ACH), polyaluminium chlorosulphate (PACS) and polyaluminium silicate sulphate (PASS), which are formulated to contain high basicity, a measure of hydroxyl ions present in the coagulant. A definition of basicity is given by Letterman (1999).

Utilization of Polyaluminium Chloride (PAC) and Tapioca
The new composite coagulant (PACTPP) developed in this study is from polyaluminium chloride (PAC) and tapioca peel powder (TPP). The aim of this study is to evaluate the efficiency of different ratio of PACTPP in coagulation of leachate through degradation of suspended solids (SS), color, and chemical oxygen demand (COD) in Simpang Renggam

Comparison of coagulation pretreatment of produced water
Two coagulants, polyferric sulphate (PFS) and polyaluminium chloride (PACl), were applied separately for the organics, suspended solids (SS), and colour removal. Treatment performance at different coagulant dosages, initial pH values, stirring patterns, and the addition of cationic polyacrylamide (PAM) was investigated in jar tests.

Polyaluminium chloride (PAC) dosing | PWTAG Technical Notes
Like all coagulants PAC works by extracting and then clumping together dissolved, colloidal and suspended matter. The resulting floc is then trapped on the filter. This note clarifies the application and dosing rates for the various different grades of polyaluminium chloride being sold in the UK.

Coagulation of soil suspensions containing nonionic or
Effective coagulation and separation of particles in a soil-washed solution is required for a successful soil washing process. The effectiveness of chitosan (CS), a polycationic biodegradable polymer, as a coagulant was compared to polyacrylamide (PAA) and polyaluminium chloride (PAC) for the coagulation of a soil suspension (5 g L −1).The effect of surfactants in the coagulation process was
