Recover free acids from waste acid and extract valuable metals contained in it through the NS process. As a result, this reduces the environmental burden caused by waste acid.
We recover free acids from acidic waste liquids using our unique control system and acid retardation method. Metal salts are separated by precipitation using the NS process, and valuable metals are recovered. Additionally, nitrogen derived from nitric acid is decomposed using microbial treatment with sensor technology.
