Summary: This study systematically examined the effects of high ammonia loading on microbial electrolysis cell (MEC) performances. It was found that ammonia loading increased the current but inhibited substrate consumption. The energy recovery efficiency of MECs remained stable, and the electrochemical activity of anode biofilm reached its peak at 1000 mg L-1 ammonia. High ammonia concentration stimulated anode biomass loss and extracellular polymeric substance (EPS) secretion. In acetate-fed MECs, carbon and methane metabolism pathways were inhibited, while in sucrose-fed conditions, glycolysis acted as the rate-limiting step for substrate degradation.

Summary: Anaerobically treated swine wastewater contains high levels of orthophosphate phosphorus, ammonium nitrogen, and organic substances which can be recovered through struvite electrochemical precipitation post-treatment. Lab-scale experiments were conducted to study the effects of initial pH, current density, and organic substances on nutrient removal and precipitate quality. The results showed that initial pH of 7.0 and current density of 4 mA/cm(2) were optimal for nutrient removal and precipitate quality, with adverse effects seen with the presence of certain organic substances like humic acid.

Summary: This paper summarizes the challenges and solutions of mainstream anammox-based process by reviewing the literature of the past decade. The slow growth rate of anammox bacteria and the need for enhancing bacteria retention are identified as the main challenges. Various methods to culture anammox bacteria and improve their activity are discussed. Other challenges include the elimination of nitrite oxidizing bacteria (NOB) and achieving the ideal ratio of NH4+ and NO2-. To overcome these challenges, composite control strategies based on low sludge retention time (SRT) and limited aeration are suggested. Interference from low temperature and influent components in actual wastewater treatment is addressed, as well as the use of coupling processes to reduce nitrate concentration in the effluent. The paper concludes with future prospects for the mainstream anammox-based process.

Summary: This review discusses the challenges of applying mainstream deammonification in sewage treatment and the impacts of unfavorable conditions on main functional species. Novel control strategies to maintain the dominant position of desired species were summarized, and an efficient solution to the conflict between AnAOB biomass retention and NOB washout was reviewed. Further studies are suggested to achieve a combination of autotrophy and organotrophy species based on the metabolic diversity of AnAOB.

Summary: The presence of organic matter affects the speciation variation of heavy metals during phosphorus recovery. Citric acid promotes the toxicity shifting of Cr and Cu to a stable state, while humic acid and tetracycline promote their shift to an active state. Chelating agents can reduce heavy metal contents in recovered struvite, but they also significantly inhibit the phosphorus recovery efficiency.

Summary: This study investigated the electrochemical recovery of phosphorus from synthetic wastewater using a sacrificial Mg anode. The results showed that higher pH and salt concentrations led to increased Mg corrosion and phosphate recovery. The primary precipitate was identified as struvite based on composition and phase analysis.

Summary: The study evaluated the performance of a double-chamber microbial fuel cell (MFC) in treating synthetic swine wastewater containing sulfonamide antibiotics. Results showed that the MFC operated better under the sequential anode-cathode mode, with higher removal efficiency of pollutants, although the removal efficiency of antibiotics still needs improvement. Antbiotics exerted toxic effects on microorganisms in the MFC.

Summary: The study revealed that different EAOPs in the treatment of TBH in synthetic wastewaters showed varying degrees of efficiency, with the highest rates of mineralization achieved through AO-H2O2/UVC and PEF processes. Furthermore, the degradation kinetics of TBH in real urban wastewater was found to be significantly lower compared to synthetic medium, indicating the impact of inorganic ions and natural organic matter on the efficiency of the electrochemical system.

Summary: This study investigated the effects of sulfadiazine (SDZ) on the performance of an anaerobic membrane bioreactor system for treating swine wastewater. It was found that higher concentrations of SDZ significantly suppressed the system's performance, but lower concentrations still achieved high COD removal and biogas production. The presence of SDZ increased the levels of soluble microbial product and extracellular polymeric substances, leading to a shorter membrane fouling cycle and changes in microbial community.

Summary: The simultaneous removal of rare earth elements (REEs) and ammonium from acidic mining drainage was achieved using immobilized acidophilic Galdieria sulphuraria (G. sulphuraria) beads. The results showed that the G. sulphuraria beads exhibited high affinity and tolerance to REEs, with a significant removal efficiency. The small size of the beads facilitated ammonium removal, and their adsorption behavior involved both physical adsorption and chemical adsorption based on ion exchange.

Summary: This study investigated the application of a reverse electrodialysis reactor (REDR) in treating synthetic methyl orange (MO) dyeing wastewater. The effects of operation parameters on the chemical oxygen demand (COD) removal efficiency were explored and a mathematical model was developed to predict the variation of COD removal efficiency with treating time under different conditions. The results showed that increasing the fluid velocity and rinse solution flowrate improved the COD removal efficiency and reduced the total energy consumption of the REDR.

Summary: Utilizing zeolite-coated hollow fiber membranes improved the growth of anammox bacteria and total nitrogen removal in mainstream-type media. Increasing the quantity of zeolite further enhanced the retention of anammox bacteria and the removal of total nitrogen. Application of membranes with higher zeolite content in integrated fixed-film activated sludge (IFAS) or membrane-aerated biofilm reactor (MABR) systems could facilitate mainstream anammox.

Summary: The recycling of critical materials from end-of-life lithium-ion batteries (LIB) has gained interest due to their limited supply and increasing demand. This study compared the environmental impacts of electrochemical leaching, peroxide-based leaching, and SO2-based leaching. The results showed that electrochemical leaching significantly reduces global warming potential and compares well with other methods in most impact categories. Renewable energy can further reduce the environmental footprint of electrochemical leaching.
