Summary: Textile wastewater contains toxic dyes that need to be removed before disposal in aquatic life. Methylene blue, even at low concentrations, has a low degradation rate and causes harm to the environment. This study examines sugarcane bagasse pulp as an effective adsorbent for removing methylene blue from textile wastewater. Batch experiments are conducted to determine the efficiency of the adsorption process, and various parameters are studied to optimize the conditions. The results show that bagasse pulp has a maximum adsorption efficiency of 95% for methylene blue removal.

Summary: Membrane wetting and fouling are major challenges in membrane distillation, especially with low surface tension components in the feed. This study developed membranes with different wettability to guide membrane selection for treating these wastewaters. Superhydrophobic and superomniphobic modifications improved anti-fouling/wetting properties when the feeds had anionic and cationic surfactants. However, these modifications worsened membrane performance when the feeds contained nonionic surfactant Tween-20. The hydrophilic layer on Janus membranes showed improvement in anti-fouling/wetting abilities for emulsified oily wastewaters, while the choice of substrate was still important.

Summary: This study investigated the performance of microalgal-activated sludge membrane bioreactor (MAS-MBR) as a self-biological treatment or post-treatment for conventional biological treatments. The results showed that cultivating mixed algae/sludge in raw wastewater achieved the best performance in terms of ammonium and phosphorus removal efficiency, as well as the highest oxygen production rate and oxygen uptake rate. However, membrane fouling was increased in this case, highlighting the need for regular membrane cleaning.

Summary: Carwash wastewater, with high turbidity and high COD, is an important issue for urban services. Chemical processes, especially coagulation, are commonly used to reduce turbidity and COD by over 80%. Due to the characteristics of the wastewater, chemical processes are necessary pre-treatments for processes like membrane technology.

Summary: This study investigated alternative methods to conventional tertiary treatment of pulp and paper wastewater, aiming to enhance the environmental and economic sustainability of industrial wastewater treatment. Cloth filtration showed good performance in removing suspended solids, while adsorption was effective in reducing chemical oxygen demand. Economic analysis suggested that a low-cost adsorbent supply chain is necessary for the economic feasibility of adsorption technology.

Summary: One important way to promote carbon reduction in the environmental industry is to promote resource recycling. Membrane separation technology has advantages in resource recovery and advanced treatment of industrial wastewater. However, traditional organic membranes face challenges such as poor organic solvent tolerance, lack of oxidation resistance, and membrane fouling control. The emerging graphene oxide (GO)-based membrane with improved characteristics shows great potential in industrial wastewater treatment.

Summary: This study evaluated the effect of alternative filtering materials and bed aeration on the retention of nutrients and fecal bacteria in woodchip bedded stand-off pads for cows. The results showed that the alternative biofilters were more efficient in removing COD, SS, TN, and NO3-N, while conventional biofilters were more efficient for PO4-P removal. Aeration did not have a significant effect under the tested temperature conditions.

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.

Summary: In this study, an electron beam excitation multi-wavelength ultraviolet (EBE-MW-UV) system was established and found to have significantly higher microbial inactivation effects compared to single-wavelength UV-LEDs in water. Mechanism analysis revealed that EBE-MW-UV damaged microbial DNA and proteins, and generated additional reactive oxygen species, leading to microbial inactivation.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
