Does polyaluminium chloride performance affect microbial community in sediments?

Multiple requests from the same IP address are counted as one view. Polyaluminium chloride (PAC) has been widely used as a chemical coagulant in water treatment. However, little is known about the impact of PAC performance on the microbial community in sediments.

Why 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 .

Does polyaluminium chloride coagulant remove turbidity from surface water?

The effect of different basicity of polyaluminium chloride (PAC) coagulant to remove turbidity from surface water was evaluated by laboratory experiments and in two different working WTPs of various capacities.

How does polymeric aluminum chloride achieve destabilization?

Polymeric aluminum chloride (PAC) achieves the destabilization process by adsorbing onto the surface of colloidal particles and facilitating bridging. Consequently, when PAC executes both destabilization mechanisms concurrently, the process becomes more rapid and results in superior separation.

Does initial concentration of aluminum chloride affect the yield of Al B?

As observed in Fig. 1 (a–d), the effects of initial concentration of aluminum chloride, basicity ratio, reaction temperature and time curves were steep slope and curvature, which revealed that the yield of Al b content in the PΑC species was very sensitive for these factors.

Does incremental addition of Pac affect turbidity removal in water treatment plants?

Incremental addition of PAC changes various physico-chemical properties and turbidity removal mechanisms in water. Water treatment plants use the PAC concentration beyond its optimum dose without considering other aspects, including residual aluminium concentration.
