Robust zirconia ceramic membrane with exceptional performance for purifying nano-emulsion oily wastewater

Xueling Wang et al.

Summary: The study reports a novel method of efficiently separating oil nano-emulsions using zirconia membranes with sub-100 nm pores and superoleophobic properties. The membrane fouling behavior is dominated by a combined model of intermediate pore blocking and cake filtration, with effective mitigation under high pH conditions. Overall, the zirconia membrane demonstrates high rejection efficiency for nano-sized oil droplets and consistent separation performance for real oily wastewaters.

State-of-the-Art Ceramic Membranes for Oily Wastewater Treatment: Modification and Application

Mingliang Chen et al.

Summary: Membrane filtration is a promising method for oily wastewater treatment, with ceramic membranes showing less fouling compared to polymeric membranes. Improving the fouling resistance of ceramic membranes is important for reducing energy consumption and increasing membrane lifespan. Different methods, including sol-gel, dip-coating, and atomic layer deposition, are used for ceramic membrane modification to enhance performance in oily wastewater treatment. Nano-sized metal oxides and graphene oxide are potential candidates for ceramic membrane modification to increase flux and alleviate fouling. Passive antifouling ceramic membranes, like photocatalytic and electrified ceramic membranes, have shown potential in fouling control, oil rejection, and flux enhancement, but also have limitations.

Optimal cleaning strategy to alleviate fouling in membrane distillation process to treat anaerobic digestate

Amine Charfi et al.

Summary: This paper investigates membrane fouling in DCMD treating anaerobic digestion sludge, defining an optimal cleaning strategy involving DI water flushing, sodium hypochlorite and citric acid cleaning. The study determines the optimal cross-flow velocity to avoid severe fouling and establishes that a cleaning duration of 60 minutes for each chemical cleaning every two days is the best strategy for membrane regeneration and process productivity. Additionally, the research shows that both external and internal fouling contribute to permeate flux decline in MD treating real wastewater.
