Abstract
Experimental work undertaken to explore the aptness of low-pressure dy namically formed membranes (DFMs) for colour removal from dyewastes is reported. Hydrous zirconium oxide-polyacrylic acid (Zr-PAA) membranes have been dynamically formed on a composite, ceramic-metal mesh micro filtration (MF) membrane at pressures and cross-flow velocities below 1.5 MPa and 3 m/s respectively. Resulting membranes were assessed on f eed steams containing inorganic salts and commercial direct, acid and basic dyes. Membrane performance, expressed as permeate flux and solut e rejection, was quantified under various feedwater conditions of salt and dye concentration, dye type and feed temperature.
