What is poly Aluminium chloride used for?

Some of the common poly aluminium chloride uses are the removal of anionic colloidal impurities and settling of suspended materials during clarification of drinking water, sewage and industrial effluents. It is also used for the removal of residual colour, TOC and to meet the discharge norms.

What is PAC used for in water treatment?

Polyaluminum Chloride (PAC) is one of the most efficient water treatment chemicals utilized today. It is widely used in both potable water and wastewater treatment because it provides high coagulation efficiency and it has the widest pH and temperature application ranges compared to other water treatment chemicals.

What is PAC dosing?

PAC Dosing is the process of adding or administering an amount of PAC into a specific volume of water. It is important to be able to accurately control the ‘dose rate’ for two reasons. Firstly, to ensure there is enough PAC to provide effective treatment.

What can poly Aluminium chloride be used for?

In addition to water treatment applications, poly-aluminium chloride can also be used in the recycled paper industry. It plays a major role in the paper industry as a filter, which can improve the purity of paper. 3.

How does poly aluminum chloride affect water quality?

Because of its good stability, the PAC dosing can be reduced under the same water quality. Especially in the case of poor water quality, the dosage of poly aluminum chloride can be reduced by half. It not only reduces the labor intensity of workers but also reduces the water production cost of users.

What are the side effects of polyaluminium chloride?

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.

Which is more expensive alum or polyaluminium chloride?

Polyaluminium chloride, or PAC is made by partial hydrolysis of aluminum chloride to form a mixture of polymeric species. It is more expensive than alum on a weight basis, but has advantage over alum such as not lowering the pH as much and better cost-effectiveness in some applicaitons.
