Summary: This study examined the impact of lightweight aggregates (FASSTT LWA) made of fly ash from sewage-sludge thermal treatment on phosphorus removal from wastewater in vertical constructed wetlands. Results showed that increasing FASSTT LWA content in the wetland filling and reducing hydraulic loading rate enhanced phosphorus removal efficiency. Wetlands filled with 100% FASSTT LWA achieved a phosphorus concentration below 2.0 mg P/L at all tested hydraulic loading rates.

Summary: To prepare low nitrogen content hydrochar, Na2SO3 and NaHSO3 were used as additives to remove nitrogen from sewage sludge during hydrothermal carbonization. The maximum removal efficiency of nitrogen in hydrochar can increase by 68.68% at 210 degrees C when 10% of Na2SO3 was added, indicating that Na2SO3 has a greater capability than NaHSO3. The key role of Na2SO3 is the degradation of extracellular polymeric substances (EPS) to release polysaccharides and destroy proteins structure, thereby inhibiting Maillard reaction and reducing nitrogen content in hydrochar.

Summary: Green lightweight aggregate produced from excavated soil and sewage sludge, known as LWA-ES, can be used as value-added materials to address urban waste and environmental pollution. This study investigated the impact of particle size and replacement level of LWA-ES on concrete performance. The analysis showed that LWA-ES with coarse particle size had a rough surface and loose structure, while LWA-ES with fine particle size had a smooth surface and dense structure. Microstructure analysis revealed enhanced mechanical interlocking between LWA-ES and cement matrix. Incorporating LWA-ES into concrete led to a decrease in density, strength, water absorption, and porosity, but improved thermal conductivity resistance.

Summary: The feasibility of using a combination of industrial sludge and water treatment sludge to produce lightweight aggregates was investigated. The chemical composition of the resulting aggregates was within the recommended range and showed good expansion characteristics. The optimal sintering parameters were determined through different experiments. The particle density and water absorption rate of the lightweight aggregates met the specification requirements, and successful sintering was achieved with an appropriate amount of industrial sludge. The use of industrial sludge not only allows for the effective utilization of industrial waste but also reduces the energy consumption in the production of lightweight aggregates.

Summary: This study investigated the treatment of soilless tomato cultivation wastewater using rotating electrochemical disk contactor (RECDC) and rotating electrobiological disk contactor (REBDC). The results showed that both reactors were effective in treating the wastewater, with RECDC achieving high denitrification and dephosphatation performance and REBDC ensuring over 90% dephosphatation effectiveness. The concentrations of pollutants in the effluent met the requirements for industrial wastewater discharged into natural waters and the ground. Technological schemes were proposed for wastewater treatment plants (WWTPs) with a RECDC and a REBDC, for discharging treated wastewater to natural waters, the ground, and sewage systems.

Summary: By studying the sludge generated during the treatment of wastewater from soilless cultivation of tomatoes, the effect of electrical direct current (DC) density (J) and hydraulic retention time (HRT) in a rotating electrobiological contactor (REBDC) on the quantity and quality of sludge was determined. The study showed that increasing J resulted in more sludge generation, while extending HRT increased the concentrations of nitrogen and phosphorus and reduced the content of organic matter. It was also found that more sludge is produced in a DC mode aerobic REBDC than in an alternating current anaerobic one.

Summary: This study investigates how precipitation and air temperature influence the efficiency of pollutant removal processes and effluent pollutant concentrations in a one-stage constructed wetland system. The research focuses on a system using Phragmites australis for treating domestic wastewater in central Europe. The results show that pollutant removal efficiency is higher during the growing season, indicating that temperature plays a significant role in wastewater treatment. The study also finds that precipitation affects the concentration of pollutants in the effluent, with higher rainfall leading to lower pollutant content and improved treatment efficiency.

Summary: This study investigated the modeling and optimization of electrocoagulation-flocculation (ECF) for the recovery of aquaculture effluent (AQE) using aluminum electrodes. The response surface methodology (RSM), artificial neural network (ANN), and adaptive neuro-fuzzy inference system (ANFIS) were employed for modeling, while the numerical RSM and genetic algorithm (GA) were used for optimization. The kinetics of the ECF process were also studied to understand its mechanism. The results showed that ANFIS performed the best in terms of prediction accuracy, and ANFIS-GA achieved the highest turbidity removal efficiency. The Elovich kinetic model had the best correlation with experimental data, indicating that electrostatic interaction governed the ECF process. This study demonstrated the effective modeling and optimization of AQE treatment using ECF, with ANFIS > ANN > RSM and ANFIS-GA > ANN-GA > RSM in terms of performance.
