Summary: Refinery wastewater, which is both voluminous and complex in composition, necessitates multi-stage treatment to meet discharge or reuse targets. Traditional pretreatment technologies using inclined plate settlement combined with two-stage air flotation for petroleum and suspension removal suffer from high energy and chemical consumption, as well as generation of significant amounts of hazardous waste. This study introduces a short-process physical pretreatment technology that employs combined fiber coalescer (CFC) and granular media filter (GMF). Pilot testing demonstrates that the treated refinery wastewater, without the addition of chemicals, becomes clear and translucent, with petroleum and suspended solids content reduced to below 20 mg/L, falling within the acceptable range of biochemical influent index. This process greatly reduces the generation and emission of scum and volatile organic compounds (VOCs), providing a new technique for low-carbon pretreatment of refinery wastewater.

Summary: This study investigated the adsorption behavior of glutathione (GSH) on amine and thiol-functionalized SBA-15 materials. Various adsorption models were used to analyze the kinetics, isotherms, and thermodynamics of GSH adsorption. The results showed that Freundlich isotherm model was suitable for simulating the adsorption of GSH on SBA-15-NH2 adsorbent, while Langmuir isotherm model was suitable for the other two substrates. Furthermore, the adsorption of GSH onto SBA-15 adsorbents was classified as physisorption.

Summary: The removal of zinc ions from water was studied using two types of ordered mesoporous silica (SBA-15 and SBA-16). Both materials were modified with APTES and EDTA through post grafting methods. The modified adsorbents were characterized by various analytical techniques, and the structural integrity was maintained. Optimal adsorption conditions and maximum adsorption capacity were determined through experimental tests, and the regenerated adsorbent showed no significant decline in adsorption efficiency.

Summary: Petroleum refineries often use the hydrodesulfurization (HDS) process to purify petroleum products and reduce SO2 emissions. However, HDS is still challenging due to various factors influencing sulfur removal rates. Machine learning algorithms can be used to predict the yields of the HDS process and help optimize it.

Summary: Mesoporous silica-based materials are being studied as bioscaffolds for bone regeneration. Zinc ion incorporation is important for bone regeneration and antimicrobial activity. This study compares the effect of pore size, geometry, and structure on the zinc loading and release of two different mesoporous silica materials. The results show that a 5 wt% zinc loading is sufficient for antibacterial effects and osteogenic differentiation of bone marrow-derived stromal cells.

Summary: The petroleum industry is rapidly growing, leading to increased environmental concerns about wastewater treatment. Advanced oxidation processes (AOP) have been applied for treating petroleum wastewater due to the limitations of conventional treatment methods. Different AOP techniques have shown varying degrees of efficiency in treating petroleum wastewater based on the contaminants present and operating conditions. Ongoing research focuses on further improving the AOP treatment methods for petroleum wastewater.

Summary: An amine-based functionalized mesoporous silica (SBA-15-TEPA) adsorbent was synthesized for the efficient and highly selective recovery of palladium from wastewater. The SBA-15-TEPA exhibited a good open pore structure, high loading rate, and significant specific surface area. It demonstrated excellent selectivity and repeatability for palladium adsorption and achieved nearly 100% recovery in column experiments.

Summary: This study aimed to develop an optimized retrieval algorithm using the random forest method and remote sensing data to monitor total nitrogen and phosphorus parameters as key drivers for eutrophication in water bodies. The water quality monitoring data of Chitgar Lake in Tehran were used, and satellite images from 2014 to 2021 were extracted. After preprocessing the satellite images and identifying important bands using the random forest method, regression models were fitted and validated. The optimal model based on Sentinel-2 data showed good accuracy in estimating the concentration of total nitrogen and total phosphorus in Chitgar Lake.

Summary: The study determined the amount and characteristics of micro- and mesoplastics in farmlands irrigated with different water sources in the south of Tehran. The abundance of microplastics was highest in farmlands with surface water irrigation, followed by groundwater and treated wastewater sources. Mesoplastics were also found in all three farmlands, with the highest abundance in groundwater irrigated fields. These findings highlight the importance of irrigation and compost fertilizing practices in soil plastic pollution.

Summary: Desalination technologies, particularly reverse osmosis systems, play a significant role in utilizing unconventional water sources for water supply. The quality and quantity of reject brine depend on various factors, including feed water characteristics, recovery rate, and desalination technology. This study investigates the potential use of reject brine as a water supply source or reducing its volume to mitigate environmental impacts in inland areas. The findings suggest that some reject brine can be directly used in agriculture, aquaculture, industry, livestock, poultry, and turfgrass. Furthermore, the study analyzes the quality of reject brine using CSMPRO4 and ROSA9 software, and explores different methods for managing reject brine, achieving a potential water recovery rate of up to 95%.
