Summary: This study proposes a hybrid system combining forward osmosis (FO) and nanobubbles (NBs) for the treatment of aquaculture effluents. The system efficiently removes organic matter, dissolved solids, and pharmaceutical chemical residues. However, the contribution of nanobubbles to direct degradation of the tested pharmaceutical oxytetracycline is minimal.

Summary: Water scarcity has negative impacts on economic, social, and ecological balance. Wastewater reuse is a solution to this issue. Forward osmosis (FO) is a popular technology, but draw solution regeneration is a key challenge. Membrane distillation (MD) is an emerging technology that offers a cost-effective purification process. Research on the integrated FO-MD process is important to overcome the limitations of individual membrane processes.

Summary: Membrane fouling and draw solution recycle are two important challenges in forward osmosis (FO) process for wastewater treatment. In this study, a corrugated TFC FO membrane (#FO-C) was innovatively designed by interfacial polymerization (IP) on a commercial corrugated PVDF substrate, and fertilizer was used as the draw solution for treating emulsified oily wastewater. The #FO-C membrane exhibited similar performance to the conventional flat TFC membrane (#FO-F), but with lower decrease in water flux in oily wastewater treatment and better recovery through surfactant cleaning and osmosis backwashing. Computational fluid dynamics (CFD) simulation showed that the corrugated pattern of #FO-C reduced fouling deposition on the membrane surface. Additionally, the diluted fertilizer draw solution could be directly used for plant irrigation, achieving draw solution recovery. This work provides a promising strategy for addressing challenges in FO process and has significant reference value.

Summary: The study demonstrated the recovery of iodide in the form of triiodide for the thin-film transistor liquid crystal display industries using forward osmosis. By preoxidizing iodide to triiodide, iodide was successfully recovered. EDTA-2Na was used as the draw solute for its low reverse salt flux and membrane distillation was shown to achieve over 99% recovery for the draw solutes with simultaneous recovery of water.

Summary: In recent years, wastewater reuse has become increasingly important in industrial zones. Reverse osmosis (RO) membranes are commonly used for this purpose, but membrane fouling is a significant issue, affecting membrane performance and lifespan. This study conducted an autopsy analysis of a fouled RO membrane from an industrial wastewater reuse plant in Turkey, revealing the presence of inorganic scaling and molybdenum contamination. An effective chemical cleaning protocol was suggested. This study provides insights into fouling control strategies for industrial wastewater reuse.

This study evaluates the effectiveness of fixed-bed granular activated carbon (GAC) filters in removing these substances and predicts their elimination based on lab-scale experiments. Nine substances were predominantly present in the drinking water and their breakthrough behaviors were observed. The removal performances and characteristics of GAC were found to be comparable to the presence of specific substances.

Summary: Membrane Distillation processes have the potential to treat highly saline solutions and achieve zero liquid discharge. Ceramic membranes, when chemically modified to exhibit hydrophobic qualities, can serve as a robust alternative to polymeric membranes in vacuum membrane distillation. This study found that the thin top layer of asymmetrically structured ceramic membranes is strong enough for highly saline and abrasive suspensions, and TiO2 membranes outperform Al2O3 membranes in terms of mass transport.
