Summary: This study investigated the mechanisms of membrane fouling in a commercial ceramic flat membrane bioreactor. It was found that the duration of backwash, charged particles, and suspended solids content are important factors influencing membrane fouling. Adjusting operating parameters and using appropriate cleaning methods can effectively reduce membrane fouling.

Summary: The effects of polyvinylpyrrolidone modification on the performance of polyacrylonitrile and polyetherimide membranes in a submerged membrane bioreactor were studied. The performance of all membranes increased with an increase in sludge retention times, while the increase in organic loading rates decreased soluble microbial products. The modification with polyvinylpyrrolidone provided higher total permeate volumes with higher rejection of soluble microbial product fractions, especially in polyacrylonitrile membranes. Membrane fouling was found to be inversely proportional to the membrane pore size, with carbohydrates and proteins identified as the main foulants on the membrane surface. The modification of polyacrylonitrile with polyvinylpyrrolidone was determined to be an appropriate approach to improve treatment efficiency and membrane lifetime in a submerged membrane bioreactor operated at high sludge retention time.

Summary: Microplastics (MPs) cannot be completely removed from water/wastewater in conventional treatment plants, but membrane technologies show promise for effective MP removal. This paper reviews the properties of MPs in treatment plants and the efficiency of their removal. It also compares different membrane filtration methods and discusses the issue of membrane fouling and potential release of MPs from polymeric membranes. The current status and research gaps in MP removal by membrane technologies are identified, and recommendations for further studies are made.

Summary: Combining a membrane bioreactor (MBR) and advanced oxidation processes (AOPs), this study aimed to efficiently treat a synthetic wastewater containing emerging pollutants. The results showed that the 10 nm track-etch membrane (TEM) had the highest removal efficiency for emerging pollutants, while the removal efficiency for total organic carbon (TOC) by membranes was low. Complete mineralization of TOC and removal of emerging pollutants were achieved using UV/PS 10 mM /ZVI 25 mg/L for MBR effluents.

Summary: The study investigated the uptake of seven organic contaminants by tomato, corn, and wheat, finding that physicochemical properties of the chemicals could predict plant uptake but other factors should also be considered. A neural network model showed acceptable accuracy in predicting transpiration stream concentration factor, however, results for compounds like 2,4-dinitrotoluene highlighted the need to consider additional parameters related to both chemicals and plant species.

Summary: Based on ground-based and satellite-based data, spatio-temporal analyses of air quality in Tehran during the lockdown periods in 2020 and 2021 were conducted. The study evaluated the differences in emissions of six air pollutants at different time scales. The results showed a decrease in pollution levels in 2020 compared to the baseline period, but a smaller reduction in 2021 and an increase in PM2.5 and PM10 levels. Satellite-based concentrations varied compared to the pre-lockdown year, with consistent trends in AOD during dust events in March and April.
