Membrane filtration is an attractive for laundry wastewater treatment especially when aiming for detergent and water reuse. However, its performance is largely restricted by membrane fouling, especially when it is run under high and trans-membrane pressure (△P) and in the sidestream configuration. The conventional treatment systems typically consist of multi-processes for removal of pollutants -including detergent- to meet the water discharge or reuse specification. This study assesses performance of a submerged membrane filtration under low △P for treatment of real laundry wastewater, obtained from local laundry shop, aiming for detergent and water reuse. Results show that low △P of as low as 0.05 bar offers the highest permeability of 297 ± 15.3 Lm⁻² h⁻¹ bar⁻¹ without significant membrane fouling. Increasing the △P leads to decreasing trend in the permeability especially in the early stages of …
