Is Pac better than aluminium sulfate flocculant?

Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better. It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9

What are the advantages of using PAC as flocculant?

CAS No.: 1327-41-9 Using PAC as flocculant, the speed of flocs forming and settling is quick. Flocs formed is easy to filter Comparing to aluminium sulfate flocculant, the quality of water treated with PAC is better; the total cost reduced by 15%~30%, and the solubility is better.

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.

Can PAC be applied to water with broad pH range?

It can be applied to water with broad pH range. The floc function valid in water of pH 5 to pH 9 Comparing to inorganic flocculants, PAC is suitable for water of broad temperature, and is functional in low temperature water. It reduces less basicity less, so less or no basifier needed.

What is polyaluminium chloride used for?

Polyaluminium chloride (aluminium chlorohydrate) also simply called PAC, is used in deodorants and as a coagulant in water purification. This compound is preferred in some cases because of its high charge, which makes it more effective at destabilizing and removing suspended materials than other aluminium salts. CAS No.: 1327-41-9

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.
