What is the difference between polyacrylamide and polyaluminum chloride?
Polyacrylamide and polyaluminum chloride are two commonly used flocculants in the water treatment industry, and they are used as water treatment to play the role of coagulation precipitation, so many people are not clear about their differences, today Xiaoqi will talk to you about the specific difference between polyacrylamide and polyaluminum chloride.
Polyacrylamide is an organic polymer, also known as organic flocculant, which can be divided into three types: cationic, anionic and non-ionic, and the appearance is white dry powder or emulsion. Mainly used in sewage treatment, raw water treatment and industrial water treatment;
Polyaluminum chloride is an inorganic polymer, also known as inorganic flocculant, the appearance of the color is diverse, mainly according to its content and change, brown, light brown, yellow, the higher the aluminum content, the lighter the color. The effect of treating sewage is also good, it has a wide range of applications, and is widely adapted to various waters. It can quickly form large alum flowers and has good precipitation performance. The suitable pH range is wide, and the pH value and alkalinity of the treated water decrease is small. When the water temperature is low, it can still maintain a stable precipitation effect. The alkalinization degree is higher than other aluminum salts and iron salts, and the effect on equipment erosion is small.
To sum up, the frequency of use of polyacrylamide in sewage treatment is given, but the use of polyaluminum chloride is also a lot, because they are different types of flocculants, so they can be used complementarily in use, and their role must be one plus one greater than two.
