Because the industrial wastewater is the most polluted place at present, and polyaluminum chloride has good effect in the treatment of industrial wastewater, so polyaluminum chloride is widely favored in the treatment of industrial wastewater. The specific performance of polyaluminum chloride in the treatment of various industrial wastewater is as follows: polyaluminum chloride is used in the treatment of wastewater from refining industry, and the removal rates of oil and COD in the wastewater treated by polyaluminum chloride are up to 92.5% and 78% respectively, which is one of the very effective and simple methods for the treatment of refinery wastewater.

Polyaluminum chloride has excellent effect in the treatment of power plant wastewater. It is not only used less, but also the pH value of treated wastewater changes little, and the corrosion of single equipment is also very small. Polyaluminum chloride products are non-toxic. The treated wastewater can be used and meet the national wastewater discharge standard. Using polyaluminum chloride to treat power plant wastewater can effectively reduce the cost.

Polyaluminum chloride was used to treat printing and dyeing wastewater. Flocculation and turbidity removal were realized by neutralization and adsorption bridge. Inorganic polymer polyaluminum chloride has strong advantages in the removal of printing and dyeing wastewater. Small volume, high water purification efficiency, the influent effect is 10% to 30% higher than other water purification agents.

Polyaluminum chloride not only has a good effect in the treatment of industrial wastewater, but also is relatively cheap. It is one of the high-quality water purifying agent products for industrial wastewater treatment. And polyaluminum chloride can also be used in other aspects of water treatment, such as urban sewage treatment, river, raw water treatment and so on.
