Can polyaluminium chloride be used as a coagulant?

The use of Polyaluminium Chloride (PAC) as a coagulant for the removal of researchers (Wang et al., 2004; Gao et al., 2002; Tapas et al., 2002). They concluded that PAC is capable of removing colour, COD and ammonia. To date, there is no reported literature on the use of PAC in leachate treatment.

Do high-poly-aluminum chloride sulfate coagulants remove humic acid?

High-poly-aluminum chloride sulfate (HPACS) coagulants with different [SO42−]/ [Al3+] molar ratio (S) were prepared and proved to have high coagulation efficiency for the removal of humic acid and strong stability for storage and application. The results showed that the higher the SO42− addition, the bigger the alum

Does polyaluminium chloride remove colour and cod from semi-aerobic water?

This research examined various experimental conditions for application of Polyaluminium Chloride (PAC) for removing colour, COD and ammonia from semi-aerobic. The removals of colour, COD and ammonia were up to 93%, 56% and 32%, respectively, at an optimum dosage of 2000 mg/L PAC.

Which coagulants have high coagulation efficiency for humic acid removal?

High-poly-aluminum chloride sulfate (HPACS) coagulants with different [SO 42−]/ [Al 3+] molar ratio (S) were prepared and proved to have high coagulation efficiency for the removal of humic acid and strong stability for storage and application.

Do coagulants remove colour and ammonia?

of colour for both coagulants were about the same (92–93%). However, the removals ammonia were 32% and 26%, respectively. The removal of colour, COD and ammonia had increased with an increas e in the concentration of PAC and alum. This trend was continuous until the optimum coagulant dos ages are reached. Excessive amount of

How does mixing speed affect coagulant removal efficiencies?

Rapid and slow mixing speed played only a minor role in the removal efficiencies for colour, COD and ammonia. The flocs size distribution for PAC coagulant shows an increase in floc size with increasing coagulant dosages. PAC also exhibited excellent settling characteristics, with majority of the flocs settled out in the initial 5 min of settling.
