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 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.

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.

What is poly Aluminium chloride (PAC)?

In the vast field of water treatment, the role of chemicals in ensuring the purity and safety of water cannot be overstated. Among these, poly aluminium chloride (PAC) has emerged as a cornerstone in both potable water and wastewater treatment processes.

How is poly Aluminium chloride used in wastewater treatment?

This is achieved through a process known as coagulation, where PAC helps to bind particles into larger aggregates that can be easily removed. In the context of wastewater treatment, poly aluminium chloride is used to treat both industrial and municipal wastewater, effectively reducing the load of organic matter and pollutants.

Does PAC coagulate?

PAC acts primarily as a coagulant, helping in the aggregation of suspended particles into larger clumps that can be easily settled or filtered from water. Is poly aluminium chloride hazardous?
