Diffusion dialysis - waste acid recovery technology

Product Description

Diffusion dialysis method (ionic membrane method) to recover waste acid adopts the principle of dialysis, which is driven by concentration difference. This product membrane and its equipment are mainly used for the separation and purification of the mixed liquid of acid and metal salts, which is a good choice in the field of waste acid. It has the advantages of simple operation, saving energy and resources, no secondary pollution, etc. The recovered acid can be recycled, and the residual liquid after separating acid can recover useful metals. It is widely used in various fields of discharge of waste acid: such as iron and steel industry, titanium dioxide industry, wet smelting of copper industry, electroplating industry, formation, rare earth industry and other non-ferrous metal smelting industry, the types of recovered acid can include sulfuric acid, hydrochloric acid, HF, nitric acid, etc., the metal ions involved mainly include transition metal ions, rare earth ions and magnesium calcium and so on. The recovery rate of acid can reach more than 80%, and the removal rate of metal ions can reach more than 90%.
