Abstract

Abstract In this work, we have optimized the process of unclogging an asymmetric membrane clogged during use in the ultrafiltration of wastewater loaded with vat dyes (indigo and sulfur black) by the method of planes experiments based on the five parameters (time of immersion, temperature, % of hydrochloric acid HCl, % of nitric acid HNO3 and % of sodium hydroxide NaOH). The optimum results obtained for a good method for unclogging are of the order of 90°C for the temperature, 70% for NaOH, 70% for HNO3, 65% for HCl and 3 minutes for the time.
