Removal of Dyes from Aqueous Solutions by Low Pressure Batch Ultrafiltration

Abstract

Abstract The use of a low pressure batch ultrafiltration method to separate dyes from aqueous solutions was investigated at 22°C. Several factors affecting the membrane performance, such as the hydraulic permeability and the rejection coefficient, were examined, including initial dye concentration, the operating pressure, as well as especially the membrane material and the ionic nature of dye molecules.
