Summary: This study proposes high-salinity treatment as a novel strategy for inactivating nitrite-oxidising bacteria (NOB) and achieving stable partial nitritation (PN). The study found that NOB are more sensitive to high salinity than ammonia-oxidising bacteria (AOB), and increasing salinity inhibited nitrification. After high-salinity treatment, nitrite accumulation rate (NAR) was above 33% during nitrification. A novel process for achieving mainstream PN was proposed and evaluated based on the results.

Summary: Until recently, nitrite oxidation was only known to occur in oxygen-rich conditions, but now it has been observed in low oxygen or anoxic environments in the ocean. However, this phenomenon is rarely reported in wastewater treatments and its mechanism is unknown. In this study, partial nitrification and nitrite oxidation were conducted in a low oxygen environment to remove nitrogen from landfill leachate. The results showed a decrease in nitrite concentration and an increase in nitrate concentration, and the main microorganisms involved were Nitrite-Oxidizing Bacteria (NOB).

Summary: Nitritation can be rapidly initiated using light irradiation, promoting the activity and growth of ammonia-oxidizing bacteria while suppressing nitrite-oxidizing bacteria. Optimal light energy densities can lead to high nitrite accumulation ratios, converting ammonia to nitrate. Additionally, light irradiation induces different responses of AOB and NOB, optimizing microbial structure while ensuring AOB predominance and stable nitritation.

Summary: The study found that the addition of hydroxylamine can promote the accumulation of nitrite in a complete nitrification reactor, leading to partial nitrification, but the process will gradually disappear after stopping the hydroxylamine addition. Analysis of the microbial community revealed that the inhibition of Nitrospira is significant and reversible, possibly related to NO toxicity.

Summary: Recirculating aquaculture systems (RAS) play an important role in water quality management and water conservation. This study compared the community structures of micro-ecosystems in RAS systems operated at different temperatures in a marine aquarium. It was found that AOA was the primary nitrifier in the biofilters, and its abundance and diversity were higher in high-temperature samples. NOB showed similar relative abundance patterns to AOA, suggesting a cooperative relationship between the two in the marine RAS system.

Summary: This study extended the conventional two-step nitrification model by incorporating complete ammonia oxidation (comammox) and heterotrophic nitrification on soluble microbial products. A new calibration protocol was proposed and the impact of initial biomass concentrations and growth rates on model accuracy was investigated using response surface methodology. The extended model was accurately calibrated and validated, providing a better understanding of the effects of initial biomass composition on two-step nitrification modeling.

Summary: Microbial nitrite oxidation is the primary pathway for nitrate generation in wastewater treatment systems, performed by various nitrite-oxidizing bacteria (NOB). However, NOB have become troublesome disruptors in advanced biological nitrogen removal, and strategies for NOB suppression often fail due to their ability to adapt to harsh conditions. This review highlights the phylogenetic and physiological diversities of NOB and emphasizes the importance of understanding their physiological characterization and genomic information in future wastewater treatment studies.

Summary: Toxicological batch assays are essential for assessing the acute effects of a compound on microorganisms. However, the experimental design criteria for nitrifying batch assays are often overlooked in the literature. This study found that slight deviations in culture preparations and conditions can significantly impact bacterial community performance and skew assay results. Factors such as media and biomass preparations, centrifugation, air supply, and organic solvents can affect nitrification activity. These factors can have substantial consequences on the determinations of toxicological endpoints and should be considered in testing methodologies.

Summary: This study demonstrates that electrolysis on boron-doped diamond electrodes is effective in removing PFASs, specifically perfluorooctanoate (PFOA) and perfluorooctane sulphonate (PFOS), from landfill leachates. The presence of long-chain intermediates during electrolysis differed significantly between high and low boron doping concentrations, indicating greater sensitivity of low-doped BDD to the long-chain intermediates of PFOA. This suggests potential for using BDD-electrolysis for PFAS removal despite the presence of competing components in landfill leachates.

Summary: Antibiotic resistance poses a major human health threat, with global asymmetries in occurrence influenced by factors such as climate, socioeconomic status, and antibiotic use. Europe shows an increasing gradient of resistance from North to South and from West to East. A qualitative comparison between Poland in Central-East region and Portugal in South-West reveals differing levels of antibiotic consumption and resistance prevalence, with potential similar resistance loads in treated wastewater.

Summary: The amount of fly ash from sewage sludge incineration is increasing globally, posing a serious environmental problem. This study utilized sewage sludge ash (SSA) from a municipal sewage treatment plant to investigate its impact on the hydration heat process of cement mortars. The research found that SSA particles have irregular grain morphology and consist mainly of oxides such as CaO, P2O5, SiO2, and Al2O3. The presence of SSA in cement mortars decreased the rate of heat generation and total heat compared to control samples. Increasing the replacement of cement with SSA also led to a decrease in the 7-day compressive strength of the mortar samples.

Summary: Electrochemical oxidation (EO) using boron-doped diamond electrodes (BDDs) was effective in treating landfill leachate (LL), with lower boron doping concentration leading to better performance. EO inactivated bacterial cells within 2 hours, possibly due to the penetration and reaction of electrogenerated oxidants. The toxicity of EO-treated LLs was lower than raw ones, suggesting that appropriate electrolysis parameters can reduce toxicity without compromising nutrient removal and disinfection capabilities, although the salinity and oxidation pathways of LLs require further investigation.

Summary: Apart from chemical constituents, wastewater treatment plant effluents release microorganisms that can be important to the receiving water bodies. Little is known about the treated wastewater microbial community and its fate in the waters of the receiver. This study uses a combination of new and traditional methods to analyze the microbial composition, functions, and seasonal changes of treated wastewater. The results show differences in bacterial community composition between treated wastewater and environmental samples, and suggest that WWTP effluents are still sources of human-related microorganisms and bacteria involved in N-cycling.
