Ageing of ultrafiltration membranes in contact with sodium hypochlorite and commercial oxidant: Experimental designs as a new ageing protocol

► Ageing of ultrafiltration membranes in contact with sodium hypochlorite and oxidant. ► An approach based on methodological tools in the chemical membranes ageing research. ► Comparison of the macro and microscopic properties of hypochlorite-aged membrane. ► Macroscopic UF membrane modifications and microscopic characterization. ► Commonly used parameter (concentration x time of exposure) to predict membrane ageing.
