The pickling wastewater are mainly produced in theacid pickling process, in which sulfuric acid, nitric acid, hydrochloric acid,hydrofluoric acid, phosphoric acid and other acids are used to remove theoxides in metal surface. This kind of wastewater mainly comes from steelfactories or electroplating factories.
Designed duty of water: 30m3/H
Raw water quality
The pickling wastewater may contain different components according todifferent acid mediums used. After the pickling process, the picklingwastewater may have 2%-4% of acid residues. According to the informationprovided 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 picklingwaste liquid can be neutralized to the pH value of 6-9 by industrial sodiumhydroxide in the wastewater pool. The reacted sodium chloride, sodium nitrateand sodium sulfate are harmless salts and can be reused directly.
