Summary: Forward osmosis is considered as a low-energy membrane process, but its high cost for draw solution regeneration hinders its maturity. Magnetic nanoparticles, with their high osmotic pressure and easy regeneration, have the potential to be a sustainable draw solute. However, significant development is still needed before implementing it for wastewater treatment and desalination.

Summary: The olive industry generates a large volume of oil mill wastewater (OMW) and table olive wastewater (TOW), which have high concentrations of organic matter, phenolic compounds, and conductivity. Proper management of these wastewaters is crucial due to their toxic impacts on the environment. Forward osmosis (FO) process was tested to concentrate phenolic compounds for recovery, and two membranes (OsmoF2OTM and HFFO.6) were evaluated. Both membranes demonstrated effective concentration of phenolic compounds with acceptable volume reduction. FO shows promise for concentrating phenolic compounds from OOWW and diluting FTOP simultaneously.

Summary: Microbial fuel cells (MFCs) and forward osmosis (FO) are efficient wastewater treatment technologies, but the selection of draw solute in FO treatment can affect MFC performance. NH4HCO3 as a draw solute in the FO-MFC system showed higher power density and Coulombic efficiency, but may inhibit microbial activity. Integration of FO with MFC can reduce energy consumption and improve nutrient recovery in wastewater treatment.

Summary: By introducing a complexing agent in forward osmosis process, the reverse solute flux can be effectively reduced to enhance efficiency. The complexation of PSS with MgCl2 inhibits the movement of MgCl2 across the membrane, leading to a decrease in RSF value. The optimal complexation affinity is achieved under non-adjusted pH conditions.

Summary: Integrated electro-Fenton and forward osmosis technology can effectively remove emerging and accumulated contaminants. The chemistry of the draw solution in forward osmosis has a significant influence on the electro-Fenton process. Factors such as the type of salt, pH, and presence of dissolved organic matters affect the degradation efficiency. Understanding the transport behavior of trace organic contaminants (TrOCs) and proposing possible degradation pathways are important for optimizing the overall treatment.

Summary: Compared to conventional anaerobic digester sludge, a microbial consortium acclimatized to lignocellulose shows higher biogas productivity and methane yield. The dominant members within the Firmicutes, Bacteroidota, and Halobacteriota phyla are responsible for the increased methane production, while the abundance of syntrophic bacteria such as Proteiniphilum, Fermentimonas, Syntrophomonas, and Methanosarcina helps maintain digester stability and improve substrate-to-methane conversion.

Summary: A systematic study was conducted to understand the bactericidal mechanism of ultrasound assisted Fenton reaction (Sono-Fenton) against multidrug resistant Acinetobacter baumannii. The study found that SF achieved approximately 99% inactivation efficiency against A. baumannii within 90 minutes under weak acidic conditions. The combination of ultrasound and H2O2 was found to be more efficient, and the generation of multiple reactive oxygen species (ROS) may have led to the membrane damage of the bacteria.
