Examples of polyaluminum chloride in industrial wastewater treatment

TIME:2023-07-21 17:33:14SOURCE:admin

The application of polyaluminum chloride in water treatment has a wide range of uses. Polyaluminum chloride, a water purification agent, has played a good role in solving water pollution and lack of water resources.

 

Polyaluminum chloride has excellent effect in treating various types of industrial wastewater. For the treatment of washing wastewater, it is easy to form colloidal particles with negative charge with oil and suspended particles. After adding polyaluminum chloride, the negative charged particles of the washing wastewater combine with the positive charged ions generated by the dissolution of polyaluminum chloride. After a series of reactions, the final precipitation is formed to achieve the purpose of water purification.

 

When polyaluminum chloride is used to treat printing and dyeing wastewater, the printing and dyeing wastewater has high COD, chromaticity and large fluctuation of pH value. Although the flocculation effect of polyaluminum chloride is good, it can not achieve the desired effect due to the large fluctuation of pH value of printing and dyeing wastewater. At this time, it is necessary to add the corresponding acid-base neutralizer, and then cooperate with polyaluminum chloride to achieve the desired effect.

 

When polyaluminum chloride is used to treat oily wastewater, single polyaluminum chloride will have certain limitations, but with some organic coagulant aids such as polyacrylamide, after coagulation and precipitation, oily wastewater can be well treated.

 

Polyaluminum chloride has an excellent effect in the treatment of industrial wastewater, but it often needs to go through the corresponding small-scale test to get a reasonable method of use, such as cooperating with other water purification agents to have a better effect.
