Does polyaluminium chloride coagulant affect the structure and diversity of pollutants?

The polyaluminium chloride (PAC) coagulant was applied to determine the impact of the treatment process on the structure and diversity of these pollutants in urban drinking 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 affect microbial community in urban river sediments?

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. In this study, the archaeal, bacterial, and fungal communities in urban river sediments with and without PAC treatment were investigated.

Can coagulation remove pollutants from urban drinking water?

Conclusions In this study, the coagulation method, which is simple and cost-efficient, is proven as an effective process to remove pollutants from urban drinking water. Although several coagulants have been experimented with for urban drinking water treatment, the PAC coagulant was investigated as efficient for TOC, TSS, and TN removal.

Does PAC coagulant reduce turbidity of urban river water?

As a chemical coagulant, PAC exhibited high efficiency in removing particles and reducing the turbidity of urban river water, with a maximum efficiency of 98%. After the addition of PAC coagulant, the TDS, salinity, and residual metals in the sediment increased in an obvious manner.

Can aluminium be used as a coagulant?

Alum has been used as a coagulant for a long time, but it has some limitations, including a narrow pH range (6.5 to 8.0) and the development of substantial amounts of aluminium residue during post-treatment .
