Homogeneous series of charged membranes and their devices (diffusion dialyzers) are the core technology products of Shandong Tianwei Membrane Technology Co., Ltd. Due to its unique properties, this product plays an irreplaceable role in chemical separation, especially waste acid recycling. The diffusion dialysis method (ion membrane method) uses the dialysis principle to recover waste acid, using concentration difference as the driving force. The membrane and its equipment of this product are mainly used for the separation and purification of mixed liquids of acids and metal salts. It is a good choice in the field of waste acid. It has the advantages of easy operation, saving energy and resources, and no secondary pollution. The recovered acid can be recycled, and the residual liquid after separating the acid can recover useful metals. It is widely used in various fields that discharge waste acid: Such as the steel industry, titanium dioxide industry, wet copper smelting industry, titanium material processing industry, electroplating industry, wood saccharification industry, rare earth industry and other non-ferrous metal smelting industries, etc. The types of acids recovered can include sulfuric acid, hydrochloric acid, HF, nitric acid, acetic acid, etc. The metal ions involved mainly include transition metal ions, rare earth ions and magnesium calcium, etc. The acid recovery rate of this device can reach more than 80%, and the metal ion removal rate can reach more than 90%.
