Introduction to Pickling Wastewater

       The pickling wastewater is the wastewater produced when the acid such as sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid and phosphoric acid is used for acid cleaning to remove oxides on the metal surface. Most of the wastewater comes from iron and steel plants or electroplating plants. The pH value is generally below 1.5 (free acid 0.5-2%), which is strongly acidic. The neutralization method is used to treat the wastewater. The neutralizers commonly used include lime, dolomite and Magnesium oxide, retarded separation method.

D.There are many options for the material of the equipment, depending on customer requirements.

       The wastewater evaporation crystallizer is mainly suitable for the evaporation and crystallization of the precipitated solution of crystals. It is widely used in the chemical industry, metal mining smelting, pickling waste liquid in large steel plants, and wet desulfurization waste liquid treatment in power plants. In view of the characteristics and complexity of various solutions, we will make specific technical solutions for the components and contents of the solutions provided by users with crystal precipitation for users' reference and choice!

       This equipment is suitable for pharmaceutical, chemical, biological, food and other industries. It is mainly used for the terminal treatment of salty wastewater. It is a commonly used equipment in environmental protection systems. You are welcome to consult and inspect.
