Certifications The whole device is a series of structural units composed of a certain number of membranes. Each unit is separated by an anionic homogeneous membrane into a dialysis chamber and a diffusion chamber. Countercurrent operation is adopted. When the spent acid solution and the receiving solution (tap water) are passed into both sides of the anionic homogeneous membrane, the concentration of acid and its salts on the spent acid solution side is much higher than that on the water side. However, the membrane has selective permeability to anions, so under the action of the concentration difference, the anions on the waste acid side are attracted and enter the water side smoothly through the membrane pores. At the same time, according to the requirements of electric neutrality, cations will also be included, because the hydration radius of H+ is relatively small, and the charge is less; The hydration radius of metal salts is larger and the charge is more, so H+ will preferentially pass through the membrane, so that the acid in the waste liquid will be separated.

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%.
