Get PriceIs polyaluminium chloride a safe coagulant?
Polyaluminium Chloride is a safer alternative to several other chemical coagulants. For instance, aluminium sulphate has been widely used as coagulant for many years. It removes contaminates and general turbidity from water during the water treatment process.
Why is polyaluminum chloride used in water treatment?
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. At present, polyaluminum chloride water treatment is not only used in industrial sewage but also widely used in urban sewage and drinking water treatment. 2.
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.
Is there an alternative preparation procedure for polyaluminium chloride (PAC)?
An alternative preparation procedure for polyaluminium chloride (PAC), a common inorganic coagulant, is presented in this paper.
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.
Can granular al be used to produce polyaluminium chloride?
An alternative way for the production of PAC should be desirable, resulting in a more effectively preparation route, regarding time and cost. In this paper, an alternative method for producing polyaluminium chloride is presented, based on the use of granular Al, as aluminium source.
