Abstract

Peatlands could contains water 20 times than it weight. Peat water is brownish red because it cointans high organic substances, therefore peat water should be treating before it can be used as clean water. Adsorption with activated carbon is potential as a method for remove color and organic substances on peat water. This research aims to investigate the characteristics of peat water and analyze the potential treating method for remove color and organic substances on peat water used activated carbon. The result showed color and organic substances on peat water was 1830 Pt/Co and 437,8 mg/L. High adsorption capacity on activated carbon could removed color and organic substance on peat water.Keywords: Peat water, adsorption

Abstract

This activity aims to provide a solution for the people of Al-Madina Housing RT 016 Sungai Mengkuang Village, Rimbo Tengah District, Bungo Regency, to treat well water that is cloudy and smells of rust into clean water with a cheap budget and a longer lifespan for use for hygiene purposes. Sanitation. The well water is cloudy and smells of rust, indicating that it contains suspended solids and metal iron (Fe). The activity method used is counseling and training in making simple water filters with cheap and easy-to-find materials. The result of the activity was that the community was enthusiastic about this activity, as evidenced by the number of residents who attended, as many as 21 people, and the number of questions asked. The results of the healthy water treatment at the activity site look clearer, and the rust smell in the water is less than before processing. This is because the filter media used in the form of activated carbon, poor sand, and dacron (filter cotton) can hold suspended solids and adsorb iron metal (Fe) in well water. By carrying out this activity, the community has become aware of the importance of clean water that complies with standard hygiene and sanitation requirements and is encouraged to make simple water filters independently. From the results of the activity, it can be concluded that: (1) the community/partners have gained an understanding of the importance of clean water by standards for sanitary hygiene requirements, (2) the community can make simple water filters independently with cheap and easy-to-obtain materials, (3) The results well water treatment in both locations look clearer and the smell of rust in the water is less than before processing.

Abstract

Abstract: Daily use of personal care products containing microbeads causes severe problems for the aquatic environment. Greywater is a pathway for microbeads to enter domestic waste and wastewater treatment plants (WWTPs) from personal care products. Their tiny size and hydrophobic nature allow microbeads to escape from WWTPs and end up in surface water. Therefore, processing efforts are needed to remove microbeads, one of which is using the electrocoagulation method with aluminum (Al) electrodes. This study aims to evaluate the performance of the electrocoagulation process using Al electrodes arranged in a monopolar configuration in a batch reactor to see the effect of variations in distance between electrodes of 1, 2.5, and 3.5 cm, stirring speed of 150, 200, and 250 rpm; with the contact time 60, 120, and 180 minutes in removing microbeads from artificial wastewater. This research shows that the best efficiency value of 99.30% occurs in operating conditions with a distance between electrodes of 2.5 cm, a stirring speed of 150 rpm, and a contact time of 180 minutes. ANOVA results showed that distance between electrodes, stirring speed, and contact time significantly affected microbead removal efficiency (p<0.05). The results of this research can be a reference for alternative tertiary processing at WWTPs.Abstrak: Penggunaan produk perawatan pribadi sehari-hari yang mengandung microbeads menyebabkan masalah serius bagi lingkungan perairan. Greywater merupakan jalur masuknya microbeads ke dalam limbah domestik dan instalasi pengolahan air limbah (IPAL) dari produk perawatan pribadi. Ukurannya yang sangat kecil dan sifat hidrofobiknya memungkinkan microbeads keluar dari IPAL dan berakhir ke air permukaan. Oleh karena itu diperlukan upaya pengolahan untuk menyisihkan microbeads, salah satunya dengan menggunakan metode elektrokoagulasi dengan elektroda aluminium (Al). Penelitian ini bertujuan untuk mengevaluasi kinerja proses elektrokoagulasi menggunakan elektroda Al yang disusun dalam konfigurasi monopolar dalam reaktor batch untuk melihat pengaruh variasi jarak antar elektroda 1, 2,5, dan 3,5 cm, kecepatan pengadukan 150, 200, dan 250 rpm, dan waktu kontak 60, 120, dan 180 menit dalam menyisihkan microbeads dari air limbah artifisial. Penelitian ini menunjukkan bahwa nilai efisiensi terbaik sebesar 99,30% terjadi pada kondisi operasi dengan jarak antar elektroda 2,5 cm, kecepatan pengadukan 150 rpm, dan waktu kontak 180 menit. Hasil ANOVA menunjukkan bahwa jarak antar elektroda, kecepatan pengadukan, dan waktu kontak berpengaruh signifikan terhadap efisiensi penyisihan microbead (p<0,05). Hasil penelitian ini dapat menjadi referensi alternatif pengolahan tersier di IPAL.

Abstract

Abstract: The increasing use of cosmetics and personal care products containing small-sized and low-density microbeads will disrupt the aquatic environment because they are difficult to remove in wastewater treatment plants (WWTPs). Electrocoagulation (EC) is an effective technology for removing microbeads from greywater. This research aims to develop an effective cylindrical electrode geometry design in the EC process to reduce electrode passivation, as evidenced by the removal of polyethylene (PE) microbeads from greywater, reduced energy consumption, and the analysis of the EC kinetics model. Experiments were carried out on batch and continuous systems using artificial greywater with an initial concentration of 0.5 g/L. Variations made in the batch system are the geometry of the cylindrical electrode without holes (ESTB), a cylindrical electrode with holes (ESB), a cylindrical electrode with anode with holes, and a cathode with no holes (ESB-A), a cylindrical electrode with cathode, with holes and anode with no holes (ESB-K), and plate electrode (EP). The variations carried out in the continuous system were flow rates of 60, 70, 80, and 90 mL/minute using the best electrode geometry design obtained from the batch system. The best removal efficiency of PE microbeads in a batch system was 98.44% in ESB-K geometry and saved 75% energy consumption compared to EP. The best removal efficiency of PE microbeads in a continuous system was 79.76% at a flow rate of 60 mL/minute. The kinetic model of the EC reaction which corresponds to the removal process of PE microbeads is a first-order reaction. Future research should focus on optimizing the design of continuous reactors so that they can be applied to tertiary processing in domestic WWTPs and industrial WWTPs.Abstrak: Meningkatnya penggunaan kosmetik dan produk perawatan pribadi (CPCP) yang mengandung microbeads berukuran kecil dan berkepadatan rendah akan mengganggu lingkungan perairan karena sulit disisihkan di instalasi pengolahan air limbah (IPAL). Elektrokoagulasi adalah teknologi yang efektif untuk menyisihkan microbeads dari greywater.

Variasi yang dilakukan pada sistem kontinu adalah laju alir 60, 70, 80, dan 90 mL/menit menggunakan desain geometri elektroda terbaik yang diperoleh dari sistem batch. Efisiensi penyisihan microbeads polyethylene terbaik pada sistem batch sebesar 98,44% pada geometri ESB-K dan menghemat 75% konsumsi energi dibandingkan EP. Efisiensi penyisihan microbeads polyethylene terbaik pada sistem kontinu sebesar 79,76% pada laju alir 60 mL/menit. Model kinetika reaksi elektrokoagulasi yang sesuai dengan proses penyisihan microbeads polyethylene adalah reaksi orde satu. Penelitian selanjutnya harus berfokus pada optimalisasi desain reaktor kontinu, sehingga dapat diterapkan pada pengolahan tersier di IPAL domestik maupun IPAL industri.

Abstract

Lake Toba as the largest volcanic lake in Southeast Asia faces a serious threat in the form of water pollution due to the activities of Floating Net Cages (KJA). This study aims to evaluate the status of water quality in the waters of Lake Toba, especially in Tongging Village, Karo Regency. The evaluation was carried out using the STORET method approach. Water samples were taken at three different time conditions (before, during, and after feeding) at five strategic points representing KJA, around KJA, and river inlets. The results showed that the concentrations of phosphate and nitrate had exceeded the quality standards of PP No. 22 of 2021, reaching 0.072 mg/L and 9.950 mg/L, respectively. The highest STORET method score was -35, indicating severely polluted water conditions. These findings emphasize the need for sustainable fisheries management in Lake Toba.
