Groundwater is an important source of drinking water for many households in Indonesia; however, its quality is often compromised by metals such as iron (Fe) and manganese (Mn). These elements degrade water aesthetics and may pose health risks, highlighting the need for simple, effective, and affordable treatment technologies. This study evaluated the effectiveness of a ceramic filter composed of five locally sourced materials—clay, sawdust, rice husk, zeolite, and activated carbon—for reducing Fe and Mn concentrations in groundwater in Makassar. The study employed a pre–post-test with control design. A single homogenized influent batch was used as the reference (Before, measured once), while the control (empty housing) and ceramic media filtration were operated in parallel under gravity flow with the feed tank elevated by approximately 2 m (floor to tank base). Five outlet subsamples were collected for each condition (n = 5; sampling points 1–5) after steady flow was achieved. The results showed that Fe decreased from 0.57 to 0.11 mg/L (81.33% removal) and Mn decreased from 2.58 to 0.49 mg/L (80.92% removal). The final Fe concentration met both the national quality standard (0.2 mg/L) and the WHO acceptability value (0.3 mg/L), whereas Mn remained above the 0.1 mg/L guideline value. Overall, the multi-material ceramic filter shows potential as a low-cost household-scale option for improving groundwater quality, although further optimization is required to achieve reliable Mn compliance. This technology supports progress toward Sustainable Development Goal (SDG) 6 on universal access to safe water and sanitation.

地下水是印度尼西亚许多家庭的重要饮用水来源；然而，它的质量经常受到铁（Fe）和锰（Mn）等金属的影响。这些因素降低了水的美观性，并可能构成健康风险，因此需要简单、有效和负担得起的处理技术。本研究评估了由粘土、锯末、稻壳、沸石和活性炭等五种当地材料组成的陶瓷过滤器在降低望加锡地下水中铁和锰浓度方面的有效性。本研究采用对照设计的前-后测试。单个均质进料批次作为参考（之前，测量一次），而对照（空壳体）和陶瓷介质过滤在重力流下平行操作，进料罐升高约2米（从地板到罐底）。在达到稳定流动后，每个条件下采集5个出口子样本（n = 5，采样点1-5）。结果表明，Fe由0.57 mg/L降至0.11 mg/L（去除率81.33%），Mn由2.58 mg/L降至0.49 mg/L（去除率80.92%）。最终铁浓度满足国家质量标准（0.2 mg/L）和WHO可接受值（0.3 mg/L），锰浓度高于0.1 mg/L指导值。总体而言，尽管需要进一步优化以实现可靠的Mn合规性，但多材料陶瓷过滤器显示出作为改善地下水质量的低成本家庭规模选择的潜力。这项技术支持实现可持续发展目标6关于普遍获得安全饮用水和卫生设施的进展。

This study investigates the impact of excess air levels on pollutant emissions (CO, NO_x, SO₂, and CO₂) and thermal efficiency during the co-firing of 95 % sub-bituminous coal with 5 % biomass pellets of various compositions, including 100 % sawdust, 100 % rice husk, and blended ratios with cocopeat. Unlike previous studies that typically focused on single biomass feedstocks or limited emission parameters, this research provides a comprehensive evaluation of multi-biomass pellet combinations under varying excess air conditions and links combustion performance to both emission reduction and thermal efficiency. The work also integrates an Analytical Hierarchy Process (AHP) approach to identify the most critical emission parameters influencing environmental performance. The results demonstrate that increasing excess air generally reduces NO_x and SO₂ emissions across all biomass types, while the optimal performance—marked by the highest thermal efficiency (74.40 %) and the lowest emission indices—was achieved for the sawdust-based configuration. This integrated thermochemical–environmental assessment offers a novel framework for optimizing co-firing operations in existing coal-fired systems to meet low-carbon transition targets.

本研究调查了过量空气水平对污染物排放（CO, NOx， SO2和CO2）和热效率的影响，在95%亚烟煤与5%不同成分的生物质颗粒共烧过程中，包括100%锯末，100%稻壳，以及与椰子油的混合比例。与以往的研究通常关注单一生物质原料或有限的排放参数不同，本研究对不同过剩空气条件下的多种生物质颗粒组合进行了全面评估，并将燃烧性能与减排和热效率联系起来。这项工作还整合了层次分析法（AHP）方法，以确定影响环境绩效的最关键排放参数。结果表明，在所有生物质类型中，增加过量空气通常会降低NOx和SO2的排放，而以木屑为基础的配置实现了最高热效率（74.40%）和最低排放指数的最佳性能。这种综合热化学-环境评估为优化现有燃煤系统的共烧操作提供了一个新的框架，以实现低碳转型目标。

Geopolymer granules containing fly ash as aluminosilicate materials and mill scale as a catalyst were applied for photocatalytic degradation of imidacloprid insecticide. The surface properties of the geopolymer catalyst were optimized by providing an optimum ratio of waste materials and pore-forming agents. The geopolymer catalyst yielded complete imidacloprid removals during batch experiments, with more than 80 % of its removals taking place after only 1 h of UV exposure. High photocatalytic activities were maintained over 10 repetitive cycles, exhibiting its longevity during which a gradual release of sediment with higher photocatalytic activities was observed, thus increasing its overall photocatalytic degradation rate of the geopolymer catalyst.

Microplastics (MPs) are increasingly recognized as contaminants in various food products, including salt, tea, honey, rice, and seafood; however, data on their occurrence in commonly consumed spices remain scarce. In this study, the presence, abundance, morphology, and polymer composition of MPs were investigated in three widely used spices—turmeric, red pepper, and black pepper—purchased in bulk (loose) and packaged forms from markets in Ahvaz, southwestern Iran. A total of 30 samples (15 bulk and 15 packaged) were analyzed using chemical digestion and density separation, followed by stereomicroscopy and Raman spectroscopy under strict contamination control procedures, including procedural blanks and recovery validation. Method sensitivity and analytical uncertainty were addressed through procedural blanks, recovery validation, and conservative particle confirmation criteria. MPs were detected in all samples, with concentrations ranging from 500 to 1100 particles/kg. Bulk spices consistently exhibited higher MP loads than packaged products, suggesting handling and environmental exposure as important contamination pathways. Fibers (61.7 %) and fragments (35.6 %) were the dominant particle morphologies, while polyethylene (PE), polypropylene (PP), and polystyrene (PS) were the most frequently identified polymers. Most particles were smaller than 100 μm. Among the studied spices, red pepper showed the highest average MP concentration, followed by turmeric and black pepper. Based on typical consumption rates, the estimated annual intake of MPs from spices ranged from approximately 188 to 613 particles per person per year, which is substantially lower than reported intakes from foods such as bottled water or salt, but represents a chronic and recurrent dietary exposure. Although limited in sample size, this study provides the first quantitative evidence of MPs contamination in common spices from Iran and highlights spices as an underreported, chronic dietary source of MP exposure.

微塑料（MPs）越来越被认为是各种食品中的污染物，包括盐、茶、蜂蜜、大米和海鲜；然而，关于它们在常用香料中出现的数据仍然很少。在这项研究中，MPs的存在，丰度，形态和聚合物组成研究了三种广泛使用的香料-姜黄，红辣椒和黑胡椒-散装（散装）和包装形式从伊朗西南部的阿瓦士市场购买。在严格的污染控制程序（包括程序空白和回收率验证）下，采用化学消化和密度分离，然后进行立体显微镜和拉曼光谱分析共30个样品（15个散装和15个包装）。方法灵敏度和分析不确定度通过程序空白、回收率验证和保守颗粒确认标准来解决。所有样品中均检测到MPs，浓度范围为500 ~ 1100粒/kg。散装香料始终表现出比包装产品更高的MP负荷，表明处理和环境暴露是重要的污染途径。纤维（61.7%）和碎片（35.6%）是主要的颗粒形态，而聚乙烯（PE）、聚丙烯（PP）和聚苯乙烯（PS）是最常见的聚合物。颗粒大都小于100 μm。在研究的香料中，红辣椒的平均MP浓度最高，其次是姜黄和黑胡椒。根据典型的消费率，估计每人每年从香料中摄入的多氯丁酸微粒约为188至613粒，这大大低于从瓶装水或盐等食物中报告的摄入量，但代表了慢性和经常性的饮食暴露。虽然样本数量有限，但本研究提供了伊朗常见香料中多磺酸盐污染的第一个定量证据，并强调香料是一种被低估的多磺酸盐暴露的慢性饮食来源。

The declining availability of fossil energy in Indonesia has encouraged the development of more environmentally friendly alternative energy sources, including the conversion of biomass waste into solid fuels such as briquettes. However, biomass briquette production still faces challenges in improving product quality. This study aims to convert durian shells and jengkol shells into raw materials for biobriquette production using molasses and tar as binders. The charcoal composition ratios of durian shell to jengkol shell employed were 80:20, 70:30, 60:40, 50:50, and 40:60, each formulated with 25% molasses and tar binder. Briquette production included carbonization at 450 °C for 1 h, sieving to pass 100 mesh, mixing with 25% binder, pressing at 25 kg/cm², and drying at 105 °C for 3 days. The resulting briquettes were analyzed based on proximate parameters and calorific value. The results showed that the lowest moisture content of 3.80% was achieved at the 40:60 composition with molasses, while the lowest ash content of 3.25% was obtained at the 50:50 composition with tar. Furthermore, the lowest volatile matter content of 1.07% and the highest fixed carbon content of 91.45% were found at the 40:60 composition with tar. The highest calorific value, 7010 cal/g, was recorded for the 80:20 composition with molasses, whereas the lowest, 5653 cal/g, occurred at the 40:60 composition with tar. All samples met the quality standards of Indonesian National Standard (SNI) No. 1/6235/2000. These findings indicate that the combination of durian shell and jengkol shell charcoal, particularly the 80:20 ratio using 25% molasses, produces high-quality biobriquettes with strong potential as an alternative biomass-based energy source.

印度尼西亚矿物能源的供应不断减少，鼓励发展更有利于环境的替代能源，包括将生物质废物转化为固体燃料，如蜂窝煤。然而，生物质型煤生产在提高产品质量方面仍面临挑战。本研究旨在以糖蜜和焦油为粘合剂，将榴莲壳和果冻壳转化为生产生物燃料的原料。榴莲壳与珍珠壳的木炭组成比例分别为80:20、70:30、60:40、50:50和40:60，其中糖蜜和焦油黏合剂的比例分别为25%。型煤的生产包括在450 °C下碳化1小时，筛分通过100目，混合25%的粘合剂，在25 kg/cm2下压制，在105 °C下干燥3天。根据近似参数和热值对成型煤进行了分析。结果表明，与糖蜜配比为40:60时，水分含量最低，为3.80%；与焦油配比为50:50时，灰分含量最低，为3.25%。与焦油配比为40:60时，挥发物含量最低，为1.07%，固定碳含量最高，为91.45%。与糖蜜的比例为80:20，热值最高，为7010卡/克；与焦油的比例为40:60，热值最低，为5653卡/克。所有样品均符合印尼国家标准（SNI） No. 1/6235/2000的质量标准。这些发现表明，榴莲壳和珍珠壳木炭的组合，特别是80:20的比例，使用25%的糖蜜，可以生产出高质量的生物煤，具有作为替代生物质能源的强大潜力。

Reverse osmosis (RO) has been widely adopted for the treatment of blow-down water to facilitate sustainable water management in thermal power plants. This study investigates membrane fouling in a packaged RO system treating blow-down water to identify the causes of permeate flux decline and develop mitigation strategies. Results from blow-down water analysis, autopsy of the used membrane, and filtration experiments indicate that the RO system was likely under-designed with water recovery exceeding the design limit, creating conditions favourable for flux deterioration. Silica, present in blow-down water at high concentrations (∼50 mg/L), was identified as the dominant and most challenging membrane fouling culprit. Given the sulphate concentrations of 55–88 mg/L, barium sulphate scaling might also occur; however, the evidence was inconclusive. Unlike silica scaling, barium sulphate could be mitigated through appropriate anti-scalant dosing. The filtration experiments indicate that besides fouling, membrane compaction partially contributed to flux decline. Finally, WAVE simulation results suggest key strategies (e.g. lower water recovery, using larger membrane surface area or membrane with improved flux stability, increasing feed water temperature (up to 35 °C), blending with silica-free water sources, and optimising anti-scalant dosing) to enhance RO system water recovery while effectively avert membrane fouling.

反渗透（RO）技术已被广泛应用于火电厂排污水的处理，以促进火电厂水的可持续管理。本研究调查了袋装反渗透系统处理排污水中的膜污染，以确定渗透通量下降的原因并制定缓解策略。排污水分析、废膜解剖和过滤实验的结果表明，反渗透系统可能设计不足，水回收率超过了设计极限，为通量恶化创造了有利条件。二氧化硅，以高浓度（~ 50 mg/L）存在于排污水中，被确定为主要和最具挑战性的膜污染罪魁祸首。当硫酸盐浓度为55 ~ 88 mg/L时，也可能发生硫酸钡结垢；然而，证据是不确定的。不像二氧化硅结垢，硫酸钡可以通过适当的抗结垢剂剂量减轻。过滤实验表明，除污染外，膜压实也是导致通量下降的部分原因。最后，WAVE模拟结果提出了提高反渗透系统水回收率的关键策略（例如，降低水回收率，使用更大的膜表面积或提高通量稳定性的膜，提高给水温度（高达35°C），与无硅水源混合，以及优化抗垢剂剂量），同时有效避免膜污染。

In 2019, a fluoride overfeed in the drinking water system of Sandy City, Utah, USA, sickened residents, corroded pipes, and released lead and copper. Sandy operators changed practices immediately, state water regulators issued administrative orders in following years, and in 2025, due partly to the incident and partly to national mood, the Utah legislature banned water fluoridation altogether—the first such ban in the United States. This case study examines the incident's technical failures (in equipment settings, control logic, and hydraulics), procedural failures (in water sampling, record keeping, and public notification), and how changes in fluoridation practice and policy escalated from a single local event to the national stage.

2019年，美国犹他州桑迪市饮用水系统中的氟化物过量，导致居民生病，管道腐蚀，并释放铅和铜。Sandy的运营者立即改变了做法，州水监管机构在接下来的几年里发布了行政命令，并在2025年，部分由于事件，部分由于国民情绪，犹他州立法机构完全禁止了水氟化——这是美国第一个这样的禁令。本案例研究考察了该事件的技术故障（设备设置、控制逻辑和液压）、程序故障（水采样、记录保存和公众通知），以及氟化实践和政策的变化如何从单一的地方事件升级到国家阶段。

Herein, Fe-, Co-doped TiO₂ semiconductors dispersed on acid-modified vermiculite were successfully synthesized using sol-gel method. The photocatalytic activity and adsorption capacity of Fe-, Co-doped TiO₂ catalysts were evaluated through the removal of ciprofloxacin antibiotic in water. Fe-, Co-doped TiO₂/Vermiculite (Ver) were mesoporous materials with specific surface areas of 162.7 m²/g (Fe-doped TiO₂), and 172.7 m²/g (Co-doped TiO₂/Ver). The combination between Fe-, Co-doped TiO₂ and Ver resulted in an improved visible light absorption, with band gap energy decreasing from 3.31 eV (TiO₂), to 2.02 eV (Fe-doped TiO₂), and 1.79 eV (Co-doped TiO₂), enhancing the photocatalytic performance and absorption capacity. The Fe-, Co-doped TiO₂/Ver achieved 96.1 % of ciprofloxacin (50 mg/L) removal by photocatalytic process. Anions inhibited photocatalytic activity with the following order Cl⁻ > H₂PO₄⁻ > I⁻, while HO^• and h⁺ were primary reactive species generated. Adsorption process followed the Freundlich isotherm (R² > 0.99) and pseudo-second-order kinetics (R² > 0.98), suggesting the involvement of physico-chemical adsorption processes. The photodegradation process adhered to pseudo-first-order kinetics, with a maximum rate constant of 0.43 min⁻¹. Co-, Fe-doped TiO₂/Ver maintained good ciprofloxacin removal efficiencies after three reused cycles, demonstrating its high stability. This study presents a promising approach for removing antibiotic residues from water.

本文采用溶胶-凝胶法制备了分散在酸修饰蛭石上的Fe- co掺杂TiO2半导体。通过对水中环丙沙星抗生素的去除，评价了Fe-、共掺杂TiO2催化剂的光催化活性和吸附能力。Fe-、co掺杂TiO2/Vermiculite （Ver）为介孔材料，比表面积分别为162.7 m2/g （Fe掺杂TiO2）和172.7 m2/g （co掺杂TiO2/Ver）。Fe-、共掺杂TiO2和Ver的结合改善了可见光吸收，带隙能量从3.31 eV （TiO2）降低到2.02 eV （Fe-掺杂TiO2）和1.79 eV (co -掺杂TiO2)，增强了光催化性能和吸收能力。Fe- co掺杂TiO2/Ver光催化对环丙沙星（50 mg/L）的去除率达到96.1%。阴离子抑制光催化活性的顺序为Cl−>； H2PO4−> I−，而HO•和h+是主要的活性物质。吸附过程遵循Freundlich等温线（R2 > 0.99）和拟二级动力学（R2 > 0.98），表明参与了物理化学吸附过程。光降解过程符合准一级动力学，最大速率常数为0.43 min−1。Co-， fe掺杂的TiO2/Ver经过三次重复使用后仍保持良好的环丙沙星去除率，表现出较高的稳定性。本研究提出了一种有前途的去除水中抗生素残留的方法。

This study investigates a compact pilot-scale continuous-flow system for turbidity removal from raw water, integrating chemical and hydrodynamic optimization. A horizontal sedimentation tank was designed and evaluated under varying conditions, including a hybrid inorganic-organic coagulant-flocculant system using polyaluminum chloride (PAC) and polyacrylamide (PAM), coagulant dosages, influent flow rates, aeration, baffle number, and inclination angle. Response surface methodology (RSM) was used to predict and optimize system performance. Optimization indicated that 45 ppm PAC and 2 ppm PAM achieved the highest turbidity removal efficiency of 94.3 % at a low flow rate of 0.5 L/min with aeration at 300 mL/min. At a moderate flow rate of 1.25 L/min, thirteen baffles set at a 75° inclination provided optimal hydraulic performance, yielding 85.3 % removal. Integration of a gravel-sand-anthracite filtration unit further increased removal to 98.3 %. RSM revealed significant interactions between influent flow rate and baffle configuration, enabling prediction and optimization of overall system performance. Mechanistic analysis illustrated floc formation behavior under different PAC and PAM dosages. By combining chemical optimization, hydraulic design, and multiple unit processes in a compact pilot-scale system, this study demonstrates an effective and adaptable approach for decentralized water treatment, suitable for rural, emergency, or resource-limited environments.

本研究研究了一种紧凑的中试规模连续流系统，用于从原水中去除浊度，集成了化学和流体动力学优化。设计了一个卧式沉淀池，并在不同的条件下进行了评估，包括使用聚合氯化铝（PAC）和聚丙烯酰胺（PAM）的无机-有机混凝絮凝剂体系、混凝剂用量、进水流量、曝气量、挡板数和倾角。采用响应面法（RSM）对系统性能进行预测和优化。优化结果表明，45 ppm PAC和2 ppm PAM在低流量0.5 L/min、曝气300 mL/min条件下，浊度去除率最高，达到94.3%。当流速为1.25 L/min时，13个挡板倾角为75°，水力性能最佳，去除率为85.3%。砾石-砂-无烟煤过滤装置的集成进一步将去除率提高到98.3%。RSM揭示了进水流量和挡板配置之间的显著相互作用，从而能够预测和优化系统的整体性能。机理分析说明了不同PAC和PAM用量下絮凝体的形成行为。通过在一个紧凑的中试系统中结合化学优化、水力设计和多个单元过程，本研究展示了一种有效且适应性强的分散式水处理方法，适用于农村、紧急情况或资源有限的环境。

Poultry slaughterhouses (PSH) face serious challenges in wastewater treatment due to the high volume of wastewater and its pollutant content. This manuscript integrates a literature review with laboratory research to provide a more comprehensive understanding of the topic. Using bibliometric analysis to identify research gaps, the study then experimentally evaluated the system by investigating the synergistic effectiveness of an integrated microfiltration and ozonation system to optimize the quality of PSH wastewater effluent. All combination treatments significantly (p < 0.05) reduced the pollution load compared to the control, except for the BOD value (p > 0.05). Optimal conditions achieved in the treatment A1B3 (20 μm filter + 15 g O₃ for 90 minutes) resulted in a 33.2 % reduction in COD (from 549.33 to 366.67 mg/L) and a 52 % reduction in TSS (from 337.33 to 162.00 mg/L). The smaller filter pore size increased filtration effectiveness and further enhanced the biodegradability of wastewater through partial oxidation. The integrated microfiltration and ozonation system demonstrated significant potential for improving the quality of PSH wastewater effluent. Furthermore, a preliminary techno-economic analysis reveals that the system is highly feasible for industrial-scale application (100 m³/day) with an estimated operational cost of USD 0.15/ m³, confirming its suitability for resource-limited settings.

家禽屠宰场的污水处理量大，污染物含量高，在污水处理方面面临严峻挑战。这份手稿整合了文献综述与实验室研究，以提供对该主题更全面的理解。利用文献计量学分析来确定研究空白，然后通过研究集成微滤和臭氧化系统在优化PSH废水出水质量方面的协同效果，对该系统进行了实验评估。除BOD值（p > 0.05）外，所有组合处理均显著降低了污染负荷（p < 0.05）。在A1B3处理中获得的最佳条件（20 μm过滤器+ 15 g O3, 90分钟）使COD降低33.2%（从549.33降至366.67 mg/L）， TSS降低52%（从337.33降至162.00 mg/L）。过滤器孔径越小，过滤效果越好，通过部分氧化进一步增强了废水的可生化性。微滤-臭氧氧化一体化系统在改善PSH废水出水质量方面具有显著的潜力。此外，初步的技术经济分析表明，该系统在工业规模应用（100立方米/天）中是高度可行的，估计运营成本为0.15美元/立方米，证实了它适合资源有限的环境。
