Potassium Hydroxide
The application of Potassium Hydroxide (KOH) in water treatment mainly includes adjusting pH value, removing heavy metal ions and organic pollutants, accelerating redox reactions, and coagulation.
Adjust pH value
Potassium Hydroxide is a strong alkaline substance that can effectively adjust and control the acidity and alkalinity of wastewater. In the process of water treatment, it is usually necessary to adjust the pH value of sewage to between 7 and 9 to ensure the normal progress of subsequent treatment steps. Potassium Hydroxide can quickly adjust acidic wastewater to a neutral or slightly alkaline range through neutralization reaction, reducing its harm to the environment
Removing heavy metal ions and organic pollutants
Potassium Hydroxide can react with heavy metal ions to form precipitates, which can effectively adsorb and remove heavy metal ions from wastewater, significantly reducing the concentration of heavy metal ions in wastewater and meeting environmental discharge standards
In addition, Potassium Hydroxide can undergo chemical reactions with organic pollutants, oxidize and decompose them, improve the biodegradability of wastewater, and create favorable conditions for subsequent biological treatment steps
Accelerated oxidation-reduction reaction
During the sewage treatment process, Potassium Hydroxide can accelerate redox reactions and improve the efficiency of sewage treatment. By accelerating this reaction process, Potassium Hydroxide can more effectively remove harmful substances from wastewater and improve water quality
Coagulation
Potassium Hydroxide can act as a coagulant for colloidal particles in wastewater and act as a weight enhancer for particle nuclei, accelerating the separation of insoluble substances. This coagulation effect helps to further purify sewage and improve treatment efficiency
