Process water treatment and recovery of product from the refinement of inorganic basic chemicals by means of membrane filtration

摘要

A chemical factory has been given the instruction form the government environmental agency that the process wastewater form the production of inorganic base chemicals must be free of individual contaminants before discharge into the sea. Since the filtration and sedimentation of these solid materials established up until now could not be performed guaranteed, suitable treatments had to be connected downstream.
