Pickling wastewater treatment:

    Pickling wastewater treatment: 

    The pickling wastewater are mainly produced in the acid pickling process, in which sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid, phosphoric acid and other acids are used to remove the oxides in metal surface. This kind of wastewater mainly comes from steel factories or electroplating factories. 

     

    Project example: Changshu Baosheng's pickling wastewater treatment project 

    Designed duty of water: 30m³/H

    The pickling wastewater may contain different components according to different acid mediums used. After the pickling process, the pickling wastewater may have 2%-4% of acid residues. According to the information provided by customers, the pickling wastewater contains hydrochloric acid, surfactant, corrosion inhibitor, metal oxides scrubbed, and various water (salt) scales deposited on the boiler heating surface, etc. 

     

    Outgoing water quality

    When the hydrochloric acid is used as the pickling medium, the pickling waste liquid can be neutralized to the pH value of 6-9 by industrial sodium hydroxide in the wastewater pool. The reacted sodium chloride, sodium nitrate and sodium sulfate are harmless salts and can be reused directly.
