Use Diffusion Dialysis Acid Recovery System

Acid waste, a hazardous substance, necessitates meticulous treatment before disposal due to its high disposal costs. However, if facilities can recover acid from waste, these costs can be significantly reduced. Moreover, reusing recovered acids minimizes the amount of acid procured, further enhancing the benefits of acid recovery systems for industries handling acid waste.

Diffusion dialysis, a membrane separation technology-based acid recovery system, is particularly suited for industries involved in metal finishing. It effectively recovers hydrochloric acid, sulfuric acid, hydrofluoric acid, and nitric acid from discarded acid baths. A notable case study demonstrates the success of this technology, where a stainless steel fittings manufacturer achieved an impressive 86% recovery of nitric acid.
