Method for desalination of tannery wastes in the nano-filtering process

摘要

The method of desulphurisation, the chromatic scrubbing effluents in the nanofiltration process, is characterized by first subjecting the chromatic scrubbing effluents (transmitter) to a preliminary pressure in the nanofiltration process, the permeate being collected in the salt concentration tank (Z2),then rinse the pre-filled chromium effluent with water to dissolve it, partially collecting the permeate in the salt concentrate tank and partially in the diluted salt solution tank (Z3),After that, the desulphurised effluent is subjected to the final pressure resulting in chromium regeneration and the permeate is collected in a diluted salt solution reservoir.
