Summary: Membrane distillation (MD) has shown effectiveness in treating hypersaline feeds by nearly completely rejecting dissolved solutes, making it a potential treatment option for hypersaline oilfield produced water (PW). However, concerns regarding membrane fouling due to low surface energy organics in PW have been raised, with various mitigation approaches showing promise but requiring further research. In comparison to other conventional treatment options, MD offers cost-effective alternatives for beneficial re-use of PW, but efforts are still needed to improve energy efficiency and explore alternative energy sources.

Summary: An oil-water separation membrane with bioinspired bubble-mediated antifouling strategy is developed to overcome the limitations of low surface energy and high viscosity of oil foulants. The membrane is superhydrophilic/superaerophobic and can catalyze hydrogen evolution, generating microbubbles that coalesce with the oil fouling and increase their buoyancy and warp their interface tension. The synergy of warped interface tension, increased buoyancy, and kinetic energy enables efficient dynamic antifouling and removal of solid sediment. The membrane maintains high flux in long-term oil-water and oil-sand-water emulsion separation, making it promising for treating industrial oily wastewater.

Summary: This study aimed to characterize the membrane foulants in a hybrid MBBR-MBR system using walnut shell as a bio-carrier for treating oilfield produced water with different TDS concentrations. The results revealed that the most significant organic compounds were microorganisms, microbial products, and hydrocarbons. The most important inorganic elements included Na, Cl, K, Ca, S, and P, which originated from NaCl, CaCO3, and Ca-P precipitates. The addition of walnut shell effectively reduced membrane fouling through scouring, altering sludge properties, and adsorbing oil compounds.

Summary: Efficient preparation of ultrathin Al2O3 ceramic membranes with desirable porosity and hydrophilicity has been achieved by a casting-phase inversion/sintering approach. These membranes exhibit exceptionally high pure water permeability and stable emulsion flux, as well as high oil rejection against real oilfield produced water. The enhanced interfacial instability during the phase inversion process contributes to reduced surface defects, while cake filtration dominates the fouling mechanism, allowing for high flux recovery by chemical cleaning.

Summary: Viscous oil separation and its highly efficient recovery is a challenging task in oil/water separation. A nondispersive solvent extraction strategy using a polydopamine modified PVDF Janus membrane has been proposed for efficient recovery of viscous lubricant oil from emulsions. The polydopamine layer facilitates the adsorption and diffusion of oil droplets through the membrane. The optimized membrane exhibited a 70% higher accumulative flux for viscous lubricant oil compared to the contrast PVDF membrane.

Summary: Polymeric membranes are commonly used in water and wastewater treatment, but pressure-driven membranes are prone to fouling and biofouling. On the other hand, forward osmosis membranes are less affected by fouling but have limited potential in wastewater treatment due to low permeation. The use of various nano-materials has been proposed to enhance membrane performance in terms of permeability, antifouling/antibiofouling resistance, and separation properties.

Summary: In this study, inexpensive biochar derived from different feedstock was synthesized and tested for Cr(VI) removal from synthetic wastewater. The physical properties of the biochar were analyzed using various techniques, and the effects of different factors on Cr(VI) removal were determined. The results showed that the biochar derived from sludge had the highest Cr(VI) removal and under optimized conditions, complete removal of Cr(VI) could be achieved. The removal mechanism was based on the reduction of Cr(VI) by nZVI on the biochar. Overall, iron-enriched sewage sludge biochar is a promising and cost-effective solution for treating low-level Cr(VI)-contaminated wastewater.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.
