This study introduces a magnetic Fe/Mg/Zn-layered double hydroxide (LDH) composite for simultaneous phosphorus recovery and sludge dewatering from municipal wastewater. The synthesized composite exhibits a high phosphorus adsorption capacity of 25.79 mg/g, a reduction in sludge-specific resistance by 77.43%, and a 24.95% decrease in moisture content. The phosphorus adsorption process follows a pseudo-second-order kinetic model and Langmuir isotherm, and chemisorption mainly drives phosphorus adsorption. The characterization results showed that precipitation, complexation, and ligand exchange were the main adsorption mechanisms of phosphorus. The material maintains excellent performance across a wide pH range (3-11), with over 90% phosphorus removal efficiency after 5 cycles of adsorption-desorption. These results demonstrate the material's potential for sustainable and cost-effective phosphorus recovery and sludge management in wastewater treatment plants.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70159"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144817623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effectiveness of the treatment was evaluated based on the reduction of key pollutants, including chemical oxygen demand (COD), biological oxygen demand (BOD), total dissolved solids (TDS), total suspended solids (TSS), oil and grease (OG), phenol, potentially toxic elements (iron, lead, nickel, and total chromium), color, and turbidity with reference to the Indonesian National Environmental Quality Standards for industrial effluents (NEQS No. 5/2014). The immobilized bacteria demonstrated high removal efficiencies for OG (up to 98%), turbidity (70%-91%), lead (90%-92%), iron (79%-84%), and COD (79%-87%). Moderate reductions were observed for BOD (38%-79%), phenol (20%-79%), TSS (79%-91%), color (37%-47%), and chromium (52%-90%), while nickel (13%-28%) and TDS (11%-15%) showed relatively lower removal efficiencies. These findings highlight the potential of Bacillus licheniformis, supported by the adsorptive capacity of bentonite, to substantially reduce multiple pollutants in POCW, although further optimization is recommended to enhance the removal of certain contaminants to meet stringent environmental thresholds.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70156"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144800411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compounds were adsorbed separately and in mixtures to examine the competitive nature of the adsorption processes. MO is known to interact with MB and ACT, whereas MB and ACT are not likely to interact due to both having electron-donating groups. When comparing the biochar adsorption capacities for these compounds when alone and mixed, biochars with both hydroxyl and carbonyl surface functional groups had higher adsorption capacities for the tested compounds when they were in mixed solutions. Biochars with only hydroxyl groups exhibited competing adsorption mechanisms and poorer adsorption capacities of aromatic compounds in complex solutions. This provides an understanding of how competing adsorption mechanisms of aromatic compounds by biochars vary depending on the dominant adsorption mechanisms of the biochar, which will allow for more effective real-world applications for water purification in the future.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70164"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12374178/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144970791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a pilot-scale up-flow anaerobic sludge blanket (UASB) reactor, with a working volume of 225 L, was operated for 130 days to treat raw distillery wastewater. Three different types of distillery wastewater, including centrate, spent caustic, and other low-strength process wastewater generated during operations (e.g., condensation water), were mixed to balance extreme pH levels and create conditions more suitable for AD. The UASB reactor demonstrated stable performance at an organic loading rate (OLR) of 10.0 kg COD/m3/day, achieving a COD removal efficiency of 86%. Average methane yield was more than 71% throughout the operation. Microbial community analysis revealed a significant increase in key syntrophic bacteria and methanogens, with Methanobacterium accounting for 55.8% of the archaeal population. Network and Mantel analyses indicated that syntrophic partnerships play a crucial role in enhancing AD of distillery wastewater under high OLR conditions. Overall, the UASB reactor exhibited high process stability, highlighting its potential for large-scale application in distillery wastewater treatment.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70153"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12312668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AMD water in the region is a suitable candidate for in situ ettringite precipitation, serving as a motivation behind the current research. The study explores the effectiveness of integrated nanofiltration (NF), and in situ ettringite (hydrous calcium aluminum sulfate) precipitation for remediation of acid mine drainage (AMD), targeting key contaminants: sulfate, iron, and aluminum. Stagewise chemical precipitation, optimized by precise pH control and reagent dosing, combined with cross-flow nanofiltration in the downstream, demonstrated over 90% contaminant removal efficiency. The presence of aluminum ions was found to have a synergistic effect on sulfate removal, leading to enhanced contaminant removal. NF membranes, integrated into the treatment process were able to remove sulfate concentrations to less than 10 mg/L. Ettringite precipitation were carried out by pH modification. XRD peaks demonstrated crystalline ettringite formation at a precise pH range of 11.5-12.5. In situ ettringite precipitation showed promise as a sustainable remediation strategy, encapsulating contaminants within a stable crystalline structure and achieving 90% aluminum reduction. This integrated remediation technique not only simplifies the treatment methodology but also offers a comprehensive solution for AMD treatment compared to standalone techniques.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70133"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional filtration membranes often require frequent maintenance and replacement due to the accumulation of contaminants, structural damage, or chemical erosion, which increase operational costs and environmental impacts. Self-healing membranes, on the other hand, offer a unique advantage by automatically repairing micro-cracks, mitigating fouling, and rejuvenating their filtration capacity. By integrating advanced materials such as graphene oxide (GO), nanofibers, and MXenes, these membranes demonstrate enhanced chemical stability, mechanical strength, and antifouling properties, making them particularly effective in applications such as oil-water separation, desalination, and the removal of heavy metals and organic pollutants. Additionally, their self-cleaning capabilities and resistance to environmental stresses significantly reduce downtime and operational inefficiencies in large-scale water treatment systems. The incorporation of smart functionalities, such as stimuli-responsive healing triggered by temperature, pH changes, or light, further enhances their adaptability to varying environmental conditions, making self-healing membranes a sustainable and cost-effective solution for long-term water remediation.","PeriodicalId":23621,"journal":{"name":"Water Environment Research","volume":"97 8","pages":"e70148"},"PeriodicalIF":1.9,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144754412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
