Abstract

ABSTRACTWater treatment plants (WTPs) produces residues in the form of alum sludge during the treatment process. In Indonesia, due to various techno-economic constraints, some WTPs are not equipped by sludge treatment systems, so the generated alum sludge is discharged directly into water bodies without appropriate treatment. This condition may pollute water bodies because alum sludge contains various contaminants such as solid particles, organic compounds, inorganic metals, aluminum, and pathogenic microorganisms. This study aims to evaluate the characteristics of alum sludge from aspects of quality and quantity, which is indispensable for the design of sludge treatment facilities. Citayam WTP (capacity of 120 L/s) in Depok City was chosen as a case study. The study was conducted in several stages as follows: (i) survey and sampling; (ii) quality analysis of alum sludge; (iii) estimation of sludge generation; and (iv) mass and volume balance analysis. Results of comparative analysis of alum sludge quality against the Regulation of Minister of Environment of Indonesia 5/2014 shows alum sludge from flocculation units meets quality standards. In contrast, alum sludge from sedimentation and filter units were exceeded for TSS, COD, and Total Coliform parameters. Quantity-wise, the estimation of sludge generation by theoretical and empirical methods was found to be 1,898 kg/day and 4,854 kg/day. Analysis of mass and volume balance using STAN software indicates that the theoretical approach is quite representative, while the empirical method tends to be over-estimated.Keywords: alum sludge, sludge quality, sludge generation, water treatment plant, case studyABSTRAKInstalasi pengolahan air (IPA) dalam proses pengolahannya akan menghasilkan residu berupa lumpur alum. Di Indonesia, akibat berbagai kendala tekno-ekonomis, masih terdapat IPA yang belum memiliki sistem pengolahan lumpur alum sehingga langsung dibuang ke badan air tanpa pengolahan. Kondisi ini berpotensi mencemari badan air karena lumpur alum mengandung berbagai kontaminan seperti partikel padat, senyawa organik, inorganik, logam aluminium serta mikroorganisme patogen. Penelitian ini bertujuan untuk mengevaluasi karakteristik lumpur alum dari aspek kualitas dan kuantitas yang merupakan informasi penting dalam perancangan sistem pengolahan lumpur. IPA Citayam (Kapasitas 120 L/detik) di Kota Depok dipilih sebagai objek studi. Penelitian dilakukan dalam beberapa tahapan yakni survei dan sampling, analisis kualitas lumpur alum, estimasi timbulan lumpur, dan analisis neraca massa dan volume. Hasil perbandingan analisis kualitas lumpur alum terhadap PermenLH 5/2014 menunjukan lumpur alum dari unit flokulasi memenuhi baku mutu sedangkan lumpur alum dari unit sedimentasi dan filter melebihi baku mutu lingkungan untuk parameter TSS, COD dan Total Koliform. Dari aspek kuantitas, estimasi timbulan lumpur yang dilakukan dengan metode teoritik dan empirik berturut-turut sebesar 1.898 kg/hari dan 4.854 kg/hari. Analisis neraca massa dan volume menggunakan software STAN mengindikasikan bahwa metode teoritik cukup representatif, sedangkan perhitungan dengan metode empirik cenderung menjadi over-estimasi.Kata kunci: lumpur alum, kualitas lumpur, timbulan lumpur, instalasi pengolahan air, studi kasus

Proses ini akan menghasilkan limbah padat, cair, maupun udara. Salah satu limbah padat yang dihasilkan adalah abu layang. Limbah abu layang ini dikatagorikan limbah bahan berbahaya dan beracun, serta dapat terjadinya penumpukan di tempat penimbunan akhir karena produksinya yang sangat tinggi. Namun, abu layang memiliki potensi sebagai bahan baku dalam memproduksi zeolit sintetik karena kandungan oksida logamnya yang cukup tinggi. Pada penelitian ini, abu layang batu bara kelas F disintesis dengan metode gabungan fusi-hidrotermal. Abu layang dan zeolit yang disintesis dikarakterisasi agar dapat dianalisis komposisi kimianya dengan X-ray Flourescence; mineraloginya dengan X-ray Diffraction; morfologi permukaan dengan Scanning Electron Microscopy; serta distribusi partikel dengan Particle Size Analyzer. Proses sintesis zeolit dari abu layang batubara pada penelitian ini menghasilkan zeolit jenis hidroksi sodalit. Selain itu, proses sintesis ini meningkatkan luas permukaan dari abu layang sebelumnya. Dari karakteristik zeolit hasil sintesis ini dapat disimpulkan bahwa zeolit ini dapat berpotensi sebagai adsorben untuk penyisihan polutan cair maupun gas pada aplikasi teknologi lingkungan dengan penelitian lebih lanjut.Kata kunci : abu layang; zeolit; hidroxi-sodalit; sintesis; fusi-hidrotermal

Abstract

Reverse osmosis is a technology to that treat treats seawater as an alternative source for of drinking water supply. Several studies confirmed that pretreatment stages, designed to tackle high salinity and organic material in seawater, contribute significantly to the reliability of SWRO technology. Despite its effectiveness, declination of the performance of SWRO after several operation times resulted in potential improvement. Enhancement of pretreatment process to increase the performance of SWRO is necessary to be investigated. A combination of powdered activated carbon and ultrafiltration (PAC/UF) is employed at a lab scale experiment using real seawater matrix collected from an outlet dissolved air flotation unit as SWRO pretreatment stage. The Experiment was conducted employing a polyethersulfone (PES) membrane with an average pore size of 30 nm at dead-end operation with constant flux of 60 and 120 L/m²·h, respectively. For activated carbon, commercial coconut shell-based PAC was added inside the membrane holder and directly deposited on top of the membrane surface. The experiment was conducted by comparing a single filtration cycle operation using UF with/without activated carbon. UF membrane filtration performance, as well as membrane retention, was observed. PAC/UF resulted in higher removal of organic concentration (UV-Vis) (93-96%) compared to UF (14-43%). Both experiments resulted in high removal up to >90% for turbidity and chemical oxygen demand. Nevertheless, insignificant removal of salts concentration (<5%) was observed. In terms of performance, combined PAC/UF revealed better performance despite a thicker layer in comparison to UF membrane at a similar filtered specific volume of water production. Therefore, a combination PAC/UF at constant flux operation was found to be promising and reliable pretreatment for SWRO. Abstrak Kebutuhan air minum mengalami peningkatan seiring bertambahnya penduduk, tetapi sumber air bersih mengalami penurunan. Hal ini berdampak terhadap pemanfaatan sumber alternatif air laut untuk pemenuhan kebutuhan air minum dengan teknologi reverse osmosis. Walaupun dapat diandalkan untuk mengurangi salinitas tinggi dan kandungan organik air laut, unit pengolahan seawater reverse osmosis (SWRO) mengalami penurunan kinerja setelah pengoperasian dalam kurun waktu tertentu. Salah satu upaya adalah dengan peningkatan proses prapengolahan untuk SWRO. Pada penelitian ini, kombinasi Karbon Aktif Serbuk dan Ultrafiltrasi mempergunakan air laut yang berasal dari outlet unit prapengolahan pada instalasi SWRO. Percobaan filtrasi dilakukan pada percobaan skala laboratorium mempergunakan membran polyethersulfone (PES) dengan ukuran pori 30 nm pada proses dead-end dengan fluks konstan 60 dan 120 L/m²·jam. Karbon aktif bubuk komersial berbahan dasar tempurung kelapa diletakan di atas permukaan membran. Percobaan dilakukan dengan membandingkan operasi siklus filtrasi tunggal menggunakan UF dengan dan tanpa karbon aktif. Parameter pemantauan kualitas air seperti kandungan organik yang dipergunakan antara lain UV-Vis, kekeruhan, kandungan oksigen kimiawi (COD), dan koduktivitas. Penelitian ini menjelaskan bahwa retensi membran PAC/UF menghasilkan penyisihan konsentrasi organik (UV-Vis) yang lebih tinggi (93-96%) dibandingkan dengan hanya mempergunakan UF (14-43%). Untuk kekeruhan dan kebutuhan oksigen kimiawi, kedua percobaan menghasilkan penyisihan yang tinggi hingga >90%. Jika mengacu pada performa filtrasi membran, volume produksi air yang dihasilkan sebanding untuk percobaan hanya dengan UF dan PAC/UF meskipun lapisan PAC/UF lebih tebal. Berdasarkan temuan pada penelitian ini, dapat disimpulkan bahwa kombinasi PAC/UF pada operasi fluks konstan dapat dipergunakan prapengolahan yang dapat diandalkan untuk SWRO.

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

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.
