Summary: This article provides a comprehensive description of the large volume sampler (LVS) used for monitoring sewer systems and surface waters, discusses its comparability and makes recommendations for sampling methods. Differences in comparability were found between homogenized and sedimented LVS samples, leading to a recommendation to use sedimented samples for particle characterization. Results showed average TSS concentrations and dominant particle fractions in CSOs from centralized treatment facilities in Bavaria.

Summary: This paper describes a continuous monitoring system for a real sewage network using ultrasonic water level sensors, implemented in Stonyfell, South Australia. Analysis of 62 data sets collected over 1 year identified two distinctive features of growing blockages, and an early detection method based on one of these features was formulated. Application of the method showed its effectiveness in detecting possible blockages and overflow events before they occur.

Summary: In rural catchments, point sources such as combined sewer overflows (CSOs) or wastewater treatment plants (WWTPs) have a significant impact on water quantity and quality, especially during events. Poorly treated wastewater from WWTPs contributes significantly to water pollution, with increasing concentrations of ammonium-N and ortho-phosphorus throughout the year. Rural settlements have a major and variable impact on stream hydrology and water quality.

Summary: This study evaluated the transformation of common illicit drug and pharmaceutical biomarkers in laboratory sewer reactors with different levels of pH, temperature, and suspended solids. The results confirmed the dominant effects of biological activities and pH on biomarker transformation in sewers, particularly for labile compounds, while the impact of temperature or suspended solids was less significant.

Summary: This study found that NH4+ regeneration rates and community biological NH4+ demand increased downstream in the Yangtze River continuum, with higher rates in the estuary. Suspended solids were the main factor influencing NH4+ recycling rates. The regenerated NH4+ in the river-estuary continuum accounted for about 14% of total N inputs, suggesting its importance as an N source for microbes and in nutrient dynamics.

Summary: The study observed increasing concentrations, loads, and yields of TN, TP, and TSS at most river stations in the eastern half of the Lake Winnipeg Basin, while decreasing or stationary trends were seen in the western stations. Nutrient and suspended solid trends were closely related to discharge patterns, especially in the Red-Assiniboine subdrainage.

Summary: The reasons for the decline in mixed liquor volatile suspended solids/mixed liquor suspended solids (MLVSS/MLSS) in a wastewater treatment plant (WWTP) were studied, and it was found that chemical oxygen demand (COD), inorganic suspended solids (ISS), total phosphorus (TP), and particle size were the most important factors influencing MLVSS/MLSS.

Summary: This study evaluated the effects of temperature, mixed liquor suspended solids (MLSS), and velocity on the removal of organic pollutants in sewer systems. The results showed that increased temperature, time, and MLSS, as well as decreased velocity, significantly increased the removal of chemical oxygen demand (COD). The Grau and Stover-Keane Canon models efficiently predicted the removal of organic pollutants in real pipeline and pilot system, suggesting their potential use in the design and control of wastewater treatment plants.

Summary: This study successfully treated poultry slaughterhouse wastewater (PSW) by combining a biological pretreatment stage, an expanded granular sludge bed reactor (EGSB), and a membrane bioreactor (MBR). The system achieved contaminant removal rates exceeding 97%, meeting the discharge standards set by the City of Cape Town (CoCT). The EGSB and MBR played key roles in reducing concentrations of total suspended solids (TSS), chemical oxygen demand (COD), and fats, oil, and grease (FOG) to acceptable levels, demonstrating an effective and low-cost method for treating medium- to high-strength wastewater.

Summary: The study tested an acid bioleaching process for recovering copper from smelter dust, achieving up to 83% copper dissolution. Chalcocyanite was found to be more easily soluble compared to other copper minerals. Further research is needed to increase copper yields from smelter dust through extended contact time at extreme temperatures and controlled parameters.

Summary: Pathobionts are opportunistic microbes that emerge as a result of perturbations in the healthy microbiome due to complex interactions of various genetic, exposomal, microbial, and host factors, leading to their proliferation, which may exacerbate inflammation, trigger autoimmune diseases, and even lead to life-threatening conditions. The current surge in microbiome research is unraveling the complex interplays between disease development and protection against pathobionts.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
