Abstract

Sidoarjo mud is a volcanic mud (VM) that continues erupting in Sidoarjo to this day. The VM has the potential to be used in water treatment technology as a reagent or catalyst due to enormous amount of discharged flow and rich mineral content. Heterogeneous Fenton is one promising process for maximizing the VM potential, however customization is essential to optimize the process. Aim: This study aimed to investigate the catalytic abilities of Sidoarjo VM in Fenton oxidation by several modification approaches, such as calcination (CVM), impregnation-calcination (ICVM), and unmodified (UVM). Methodology and results: Fenton oxidation was carried out in a batch reactor system with the following conditions: initial congo red (CR) concentration= 50 mg/L; VCR=300mL pH=2; agitation speed=300 rpm; catalyst dosage=0.5 g/L; dan H2O2 concentration=485 mg/L. The highest performance results were achieved when the process was combined with adsorption, at 90% (CVM), 55% (ICVM), and 52% (UVM), respectively. Conclusion, significance, and impact study: The Sidoarjo volcanic mud shows high potential as a Fenton catalyst in the UVM modification technique with CVM reveals to be more suitable as an adsorbent.

Abstract

Water treatment plants (WTP) in Indonesia generally use a physical-chemical process that generates a massive volume of sludge as waste. This sludge is typically discharged into the river without sufficient treatment due to land availability and/or treatment cost constraints. Aim: This study aimed to recycle the alum sludge from a drinking water treatment plant as an adsorbent for removing dye from wastewater. Methodology and results: Alum sludge was activated by several methods including calcination at 400oC and 600oC (AS-CAL400 and AS-CAL600), gelation (AS-GEL), synthesis of TiO2-alum sludge composites (TiO2@AS), and synthesis of ZnCl2-alum sludge composites (ZnCl2@AS). The adsorbents were characterized by SEM-EDS, XRF, BET, and pHPZC. The adsorption assays were carried out in a batch system and used synthetic wastewater containing Rhodamine-B dye as a model contaminant. The result shows that the highest dye removal of up to 87% was obtained using ZnCl2@AS adsorbent, contact time of 2 hours, the adsorbent concentration of 3 g/L, initial dye concentration of 50 mg/L, and pH 2. Conclusion, significance and impact study: The conclusion shows that recycled alum sludge, especially when activated with ZnCl₂, is highly effective for removing Rhodamine B dye from wastewater. It achieved 87% removal efficiency and 26 mg/g adsorption capacity under optimal conditions. The adsorbent has a rough surface with a 128.60 m²/g area, and its adsorption behavior follows the Freundlich isotherm and pseudo-second-order kinetics. Further research including long-term use, and application in real dye wastewater should be conducted to evaluate the feasibility of this adsorbent.

Abstract

Trihalomethanes (THMs) are disinfection by-products formed from the reaction of disinfectants with natural organic matter (NOM). Aims: This study aimed to analyze the presence of NOM as precursors and THMs removal using a integration of granular activated carbon (GAC) and electrochemical membrane reactor (MER) in drinking water treatment (DWT). Methodology and results: Analysis of GAC performance in reducing NOM through variations in carbon dosage and reaction time. MER is an advanced treatment to reduce THMs in drinking water treatment with parameters of current density and reaction time. The DWT raw water contained NOM: DOC concentration of 5.18 ± 1.99 mg/L and SUVA of 2.04 ± 1.02 L/mg m. Conventional DWT remove 4-60% of NOM. The addition of GAC increases NOM removal up to 68%. MER can remove THM with 40 - 80% for chloroform and bromodichloromethane, while for chlorodibromomethane and bromoform, the removal is 10-50%. Conclusion, significance and impact study: The integration of GAC-MER increases NOM removal up to 90%, and the integration of MER-GAC reduce THMs up to 40-62%. The optimum condition of MER for NOM and THMs removal is at a current density of 20 mA cm-2 and a reaction time of 1 hour. This study is expected to be useful for DWT to control the formation of DBPs that are harmful to human health. The application of MER can reduce DBP as well as other pollutants because MER treatment is a combined treatment of membrane filters and electro-oxidation, and the addition of GAC increases the pollutant removal.

Abstract

Pencemaran plastik menjadi isu lingkungan yang krusial yang berdampak pada kesehatan manusia dan kualitas lingkungan. Plastik bersifat persisten dapat terdegradasi menjadi mikroplastik dan terakumulasi di perairan. Sungai sebagai sumber utama air baku instalasi pengolahan air minum (IPAM) menjadi jalur masuk mikroplastik ke sistem penyediaan air. Meskipun IPAM dirancang untuk menghasilkan air yang aman bagi masyarakat, teknologi pengolahan yang ada belum sepenuhnya efektif dalam menyisihkan mikroplastik. Penelitian ini bertujuan untuk memberikan informasi dari beberapa hasil penelitian terkait efisiensi penyisihan mikroplastik pada IPAM melalui pendekatan systematic literature review menggunakan metode PRISMA 2020. Artikel dikumpulkan dari database ilmiah dengan rentang tahun 2020–2025 berdasarkan kata kunci terkait mikroplastik pada instalasi pengolahan air minum. Sebanyak 20 artikel terpilih dianalisis lebih lanjut. Hasil kajian menunjukkan bahwa efisiensi penyisihan mikroplastik di IPAM bervariasi antara 30–99%, dipengaruhi oleh perbedaan metode analisis mikroplastik, kelimpahan dan karakteristik mikroplastik, teknologi pengolahan, serta faktor musim. Bentuk dominan mikroplastik adalah fiber dan fragmen yang umumnya berasal dari aktivitas domestik. IPAM dengan sumber air baku sungai cenderung memiliki kelimpahan mikroplastik lebih tinggi dibandingkan danau atau waduk. Unit filtrasi merupakan proses paling efektif dalam penyisihan mikroplastik, namun teknologi lanjutan seperti membran diperlukan untuk meningkatkan efisiensi, terutama untuk partikel berukuran kecil.

Abstract

Lumpur alum, produk sampingan dari koagulasi berbasis aluminium sulfat dalam pengolahan air, menunjukkan potensi yang menjanjikan sebagai adsorben berbiaya rendah untuk pengolahan air limbah. Studi ini mengevaluasi kinerjanya dalam menyisihkan zat warna metilen biru (MB) dan mengeksplorasi potensi regenerasi adsorben bekas pakai melalui proses oksidasi Fenton. Eksperimen adsorpsi batch dilakukan dengan konsentrasi MB 100–1000 mg/L, dosis 5 g/L, dan pH 7. Adsorben baru mencapai hingga 92% penghilangan MB pada 100 mg/L; namun, efisiensi turun menjadi 28% pada siklus kedua karena saturasi situs aktif dan penyumbatan pori. Regenerasi oksidasi Fenton mengembalikan kapasitas adsorpsi menjadi 74% melalui degradasi adsorbat, pembukaan kembali pori, dan modifikasi permukaan. SEM-EDX, FTIR, dan karakterisasi pori mengkonfirmasi perubahan morfologi dan komposisi, serta pemulihan sebagian luas permukaan, yang selanjutnya didukung oleh analisis kolorimetri dan pengukuran kandungan karbon. Temuan ini menunjukan lumpur alum sebagai adsorben berkelanjutan, dengan oksidasi Fenton yang menyediakan strategi regenerasi yang efektif dan selaras dengan prinsip-prinsip ekonomi sirkular.

Abstract

The Sidoarjo volcanic mudflow disaster in East Java, which began in 2006, has caused ongoing environmental and socio-economic challenges. However, the volcanic mud’s unique composition, rich in silica (SiO?), alumina (Al?O?), and iron oxide (Fe?O?), presents significant potential for resource recovery. This review utilizes a Systematic Literature Review (SLR) approach, following the PRISMA 2020 guidelines, to analyze 49 relevant publications from 2013 to 2024. The findings indicate that treated Sidoarjo mud can be effectively utilized in various civil engineering applications, including ceramic tiles, concrete bricks, geopolymer binders, and road base stabilizers, fulfilling national performance standards while contributing to reduced carbon emissions and construction costs. Moreover, Sidoarjo mud demonstrates its value in environmental engineering, showing effectiveness as an adsorbent for heavy metals, dyes, and organic pollutants in water treatment, as well as serving as a catalyst support in biodiesel production. This review underscores the multidisciplinary value of Sidoarjo mud, positioning it as a key material in advancing circular economy practices and promoting environmentally sustainable innovations within the built environment.

Abstract

Microplastics (MPs) are <5 mm synthetic polymer particles that are emerging contaminants and have been found widely in various water bodies. Wastewater treatment plants (WWTPs) play an important role in containing the release of MPs into the environment, but studies on the effectiveness of greywater-based WWTP, especially in dense urban areas such as Jakarta, are still limited. This research was conducted on a greywater WWTP with Moving Bed Biofilm Reactor (MBBR) technology in South Jakarta to analyze the abundance, efficiency of dispensation, and characteristics of microplastics based on shape, color, size, and material. Samples were taken from five points on weekdays and holidays, analyzed using NOAA methods and FTIR spectroscopy. The abundance of MPs at the inlet reached 942 particles/L (weekdays) and 675 particles/L (holidays), while at the outlet there were 290 particles/L and 211 particles/L, resulting in a dispensing efficiency of 69%. Five types of MPs (foam, fragment, fiber, film, microbead) were found with color variations (white-transparent, yellow, red, blue, green, black), as well as the content of PVFM, PVB, PVA, silicone, and POM polymers. This study contributes to the understanding of the distribution and character of MPs in greywater treatment systems that are still rarely explored, as well as supporting the development of mitigation strategies based on WWTP technology
