Uses of calcium chloride in sewage treatment

                                        Uses of calcium chloride in sewage treatment

Neutralization effect: Calcium chloride aqueous solution is slightly acidic and can be used to neutralize the pH of sewage, which is very important for regulating and controlling the pH value of sewage, and helps maintain the stability of the sewage treatment system and extend the service life of the equipment.

Sterilization and disinfection: After calcium chloride is dissolved in water, its chloride ions have a sterilization and disinfection effect, which can effectively kill bacteria in sewage and reduce the toxicity of water bodies.

Displacement effect: Calcium ions can replace metal cations in water, especially in the treatment of wastewater containing metal cations, which helps to reduce the damage of metal cations to the biochemical treatment process. Calcium chloride plays a key role in the pretreatment process by removing these toxic and harmful substances.

Filter aid effect: Calcium chloride can be used as a filter aid in wastewater treatment to help filter out suspended matter and impurities in sewage and improve treatment efficiency

In summary, calcium chloride can not only effectively neutralize sewage and sterilize and disinfect in sewage treatment, but also remove harmful substances in sewage through displacement, and improve treatment efficiency as a filter aid. It is a multifunctional sewage treatment agent.
