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: This study investigated the feasibility of a novel protocol for simultaneous wastewater treatment and sustainable fertigation in an osmotic membrane bioreactor. The results showed that different fertilizers had critical effects on system performance, with potassium chloride resulting in the highest water recovery and ammonium nitrate causing the lowest. The fouling layer on the membrane was mainly composed of irreversible and hydrophilic foulants, with protein and polysaccharides being the dominant compounds. Based on the performance matrix, a fertilizer index was constructed using multi-criteria decision analysis, with MAP identified as the most suitable fertilizer. Numerical simulation also revealed that MAP maintained high performance during long-term operations.

Summary: Combined heat and power systems can reduce energy and carbon footprints of wastewater treatment plants, but high capital costs may deter their installation. This study uses annual and hourly data to size a combined heat and power system for a wastewater treatment plant and calculates the savings. The results show discrepancies between the annual and hourly analyses, mainly due to the variability in biogas and natural gas consumption.

Summary: In this study, the performance of pressure-retarded osmosis (PRO) using NaHCO3-enriched geothermal water and geothermal brine was examined. The results showed that increasing the draw solution temperature improved water flux without compromising reverse salt flux, leading to lower salt-to-water flux ratios compared to NaCl-based solutions. Physical cleaning methods were found to be more effective than chemical cleaning methods in terms of permeability recovery ratio and foulant morphology. The presence of Ca2+ in the draw solution resulted in a significant drop in water flux and reverse flux decrease due to the formation of a dense fouling layer. The water flux in PRO using geothermal brine as the draw solution was influenced by ionic compositions rather than pH levels.

Summary: Microbiologically influenced corrosion (MIC) is a destructive phenomenon that can occur in diesel mixture storage tanks, particularly due to the presence of biodiesel. The study identified the bacteria responsible for MIC and found that B. licheniformis can produce gamma-polyglutamate as a corrosion inhibitor. This suggests that B. licheniformis-mediated biocorrosion may promote the use of biodiesel as an environmentally friendly biofuel.

Summary: This study proposes a novel method using onion peel as a biostimulant to enhance microalgae biomass productivity. The extraction parameters were optimized using the response surface methodology (RSM) and showed a strong correlation with microalgae biomass concentration and lipid content. The biostimulant extracted under optimal conditions exhibited promising bioactivities, including antioxidant activity and phenolic and flavonoid content. These findings suggest that onion waste-derived biostimulant can significantly promote microalgae proliferation, providing a roadmap for high-density microalgae farming and improving the efficiency of the microalgae industry.

Summary: In order to enhance the efficiency of microalgae capturing CO2 from flue gas, a nanofiber membrane containing iron oxide nanoparticles (NPsFe2O3) was prepared for CO2 adsorption and coupled with microalgae utilization. The nanofiber membrane with 4% NPsFe2O3 exhibited the largest specific surface area of 8.148 m2 g-1 and pore size of 27.505 angstrom. The membrane effectively prolonged CO2 residence time and increased CO2 dissolution. In the Chlorella vulgaris culture process, the biomass productivity, CO2 fixation efficiency, and carbon fixation efficiency were improved by 1.4 times with the presence of two layers of the nanofiber membrane compared to the group without the membrane (0 layer).
