What are the functions of calcium chloride in wastewater treatment

1. PH neutralization of sewage treatment agent.

2. Wastewater treatment as filter aid.

3. Disinfection and sterilization: the chloride ion dissolved in water by calcium chloride has the effect of disinfection and disinfection.

Chloride ion can sterilize water, kill harmful bacteria and weaken the toxicity of water; Calcium ion can replace the metal cations contained in the effluent, separate and discharge the toxic heavy metal ions, and exclude the calcium ion precipitation. The more important adsorption method is activated carbon.

The barrier method is to pass the water through the filter material, so that the impurities with large volume cannot pass through, so as to obtain cleaner water. In addition, the physical method also includes the precipitation method, which allows the heavier impurities to float on the water surface, fish out, and precipitate the heavier impurities under the water, so as to obtain; Chemical methods use various chemicals to convert impurities in water into substances that do less harm to human body, or concentrate impurities.
