What is polyaluminium chloride (PAC)?

Polyaluminium chloride (PAC) is a widely used water treatment chemical. It has a wide range of PH adaptation and it is not easy to produce color or other side effects. After the use of poly aluminum chloride, the content of iron, manganese and other heavy metals in water is low, which has a little corrosive effect on the equipment.

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.

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 polyelectrolyte –polyaluminium chloride Formance improve coagulation performance in water treatment?

At the Barekese Water Treatm ent Plant in Ghana, an alternative, the polyelectrolyte –polyaluminium chloride formance than alum-based coagulation. The aim of this study was to determine the optimal coagulant dose, mixing speed and operating pH for enhanced performance in water treatment.

Can poly aluminum chloride be applied to sewage treatment?

It can be applied to sewage treatment because it has a wide range of application to PH value and short settling time. The application of poly aluminum chloride in water treatment can ensure the quality of water sources to a certain extent and reduce the harm to human health.

What is the optimal pH range for Pac coagulation?

The optimal pH range for PAC coagulation performance was 7.5 to 8.0. The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
