Coagulation behavior of polyaluminum chloride: Effects of pH ...

Although the mechanism of coagulation with non-prehydrolysed and prehydrolysed aluminium salts is the same, the presence of polymeric forms of aluminium in polyaluminium chloride solutions makes them more stable in water, providing more effective removal of impurities and lower concentrations of aluminium remaining in the treated water.

Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?

At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.

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.

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. Pulau Burung Landfill Site in Penang, Malays ia.

How does poly aluminum chloride affect sludge production?

PAC benefited the aggregates of sludge flocs. PAC caused more EPS remained in sludge cells. Solubilization, hydrolysis, acidiogenesis, and methanogenesis were inhibited by PAC. Alb and Alc were the contributors to the decreased SCFA production. Poly aluminum chloride (PAC) is accumulated in waste activated sludge at high levels.

What is a polyaluminium chloride (PACL)?

The IPFs, such as polyaluminium chloride (PACl) and polyiron chloride (PICl), are a category of partially neutralized metal salts with significant polymeric fraction present in some circumstances.

How does poly aluminum chloride affect short-chain fatty acids (SCFA) production?

Alb and Alc were the contributors to the decreased SCFA production. Poly aluminum chloride (PAC) is accumulated in waste activated sludge at high levels. However, details of how PAC affects short-chain fatty acids (SCFA) production from anaerobic sludge fermentation has not been documented.
