At present, the effect of polyaluminum chloride in the treatment of industrial wastewater is very good. In the treatment of some chemical wastewater, polyaluminum chloride is often used in the treatment, such as acid-base wastewater, fertilizer wastewater, plastic wastewater, pharmaceutical wastewater and so on.

The effect of using polyaluminum chloride to treat chemical wastewater is very good. By adding polyaluminum chloride into the wastewater treatment process, many harmful substances such as suspended matter, acid-base, organic matter and COD can be removed from the chemical wastewater. According to the treatment of different chemical wastewater, polyaluminum chloride has great difference in use. After the pollutants in the chemical wastewater are removed by polyaluminum chloride, the remaining ones that are difficult to treat can be treated by biodegradation to ensure that the chemical wastewater can meet the relevant national wastewater discharge standards.

Of course, because most of the chemical wastewater is very difficult to treat, so in the process of using polyaluminum chloride, most of the time other water purification agents are needed to cooperate with the use, such as polyacrylamide, activated carbon, etc. these water purification products are also one of the common agents used in sewage treatment. Through the combination of polyaluminum chloride and other water purification agents, the chroma, odor, grease and heavy metals in chemical wastewater can be removed more cleanly. However, the choice of polyaluminum chloride with different chemical wastewater is different, which needs to be determined by small-scale test.

In the treatment of chemical wastewater, industrial grade polyaluminum chloride is generally used. This kind of polyaluminum chloride has better effect in the treatment of industrial wastewater, and the price is very low.
