Acid and Alkali Dosing System

System Description
Acid-base wastewater is highly corrosive. If discharged directly without management, it will corrode pipelines, channels, and structures. When discharged into water bodies, it alters the pH value, disrupts natural self-purification processes, and impacts the ecological environment. Therefore, the pH value of acid-base wastewater must be controlled within a specific range. Manually dosing acid or alkali into the water is the most direct and effective method to meet this requirement. This process purifies wastewater through neutralization. The fundamental principle is to facilitate the interaction between H⁺ in acidic wastewater and added OH⁻, or OH⁻ in alkaline wastewater and added H⁺, to form weakly dissociated water molecules and other soluble or insoluble salts, thereby eliminating harmful effects. This method enables the treatment, recycling, and pH regulation of both acidic and alkaline wastewater.
Commonly used acid-base neutralizing agents include sulfuric acid, hydrochloric acid, sodium hydroxide, calcium hydroxide, and sodium carbonate.
