Summary: This paper evaluated the influence of solids retention time (SRT) on the formation of microalgal-bacterial aggregates during the treatment of municipal wastewater in continuous high-rate algal ponds (HRAP). The results showed that increasing the SRT favored solids separation, but had no effect on COD removal and chemical composition. The best removal of nitrogen, phosphorous and suspended solids was achieved at an SRT of 12 days.

Summary: The study found that ozonation led to a dose-dependent increase in biological activity, particularly for substances that are recalcitrant to biodegradation. Additionally, ozonation enhanced the degradation potential of COD and BDOC, while also partially mineralizing organic compounds. These results suggest that a combination of ozonation and biological post-treatment can contribute to sustainable water resource management by reducing biodegradable organic carbon emissions.

Summary: Maize lime-cooking wastewater was treated by fermenting it with an alkaliphilic microalgae-cyanobacteria consortium (AMC) or by mixing it with a mineral salt medium (MSM) to decrease its chemical oxygen demand (COD). The results showed that the COD removal efficiency of sterilized wastewater exceeded 50% after 12 days. The growth of AMC was not significantly related to COD reduction, but rather to the consumption of total soluble carbohydrates (TSC). Further research is needed to investigate the amino acid composition, functionality, and stability of the potential single-cell protein (SCP) for its application in functional foods.

Summary: This study aims to understand global machine-learning (ML) prediction models for wastewater treatment plants (WWTPs). The paper evaluates the development of local and global prediction models to predict biochemical oxygen demand (BOD5) in four WWTPs. The results showed that the developed local model reduced test duration from five days to three hours, while the global model failed to achieve good predictions due to varying biological factors. The study concludes that a local model should be developed for each WWTP separately.

Summary: Municipal wastewater treatment in Mashhad, Iran is focused on removing hazardous organic matter. Downstream GAC units are necessary to reduce COD and BOD concentrations by 80-94% to meet effluent treatment, as secondary treatment only reduces 47% of residual COD and BOD. This study analyzes different types of GAC for COD and BOD adsorption at different contact times and dosages, with GAC = 0.25 proving to be effective in removing 91% of COD and 93% of BOD.

Summary: We investigated the catalytic application of sulphonated cellulose based solid carbon catalyst for the conversion of oleic acid to methyl oleate-biodiesel production under microwave irradiation. The optimized reaction conditions using response surface methodology (RSM) were found to be methanol to oleic acid molar ratio (MOMR) of 21:1, 60 min reaction time, 8 wt % catalyst loading, and a temperature of 80 degrees C, resulting in a predicted biodiesel yield of 96.77% and an experimental yield of 97.6 +/- 0.2%. The catalyst showed good recyclability for at least 5 reaction cycles, making it a promising candidate for sustainable biodiesel production.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
