“…Although adsorption owing to electrostatic repulsion, hydrophobic interactions, and adsorption on the fouling layer can all play a role, size exclusion is the primary mechanism of membrane filtration. 47 , 48 The size exclusion method mostly applies to uncharged MPs, although molecular shape should also be taken into account. MPs adhere to membrane surfaces by hydrogen bonding and hydrophobic contact.…”

Introduction: Various review papers have been published regarding the occurrence and fate of micropollutants (MPs). MPs in the aquatic environment are still not well reviewed to generate comprehensive summaries with a special focus on their removal from wastewater using conventional and advanced treatment processes. Therefore, this review aimed to provide a synopsis of the efficiency of the advanced wastewater treatment plants in the removal of MPs. Materials and methods: A systematic search of published literature was conducted on the National Library of Medicine (NLM) database, Web of Science, Joanna Briggs Institute (JBI) database, Scopus, and Google Scholar, based on studies with evidence of removal of MPs in the wastewater treatment process. Screening of the published articles was made using pre-specified inclusion and exclusion criteria. Results: Amongst the 1545 studies searched, 21 full-length articles were analyzed that showed 7 treatment options related to the removal of MPs from wastewater. MPs from wastewater effluents were successfully and effectively removed by advanced treatment techniques. Advanced Oxidation Processes (AOPs), membrane processes, and adsorption processes have all been shown to be potential solutions for the removal of MPs in advanced treatment plants (WWTPs). But, there are 2 critical issues associated with the application of the advanced treatment options which are high operational cost and the formation of dangerous by-products and concentrated residues. Conclusion: This study identified that the removal of MPs using WWTPs was commonly incomplete with varying removal efficiency. Therefore, the adaptation and scale-up of the cost-effective and efficient combined wastewater treatment technology are vital to creating an absolute barrier to MPs emissions.

“…Akan tetapi memiliki kemampuan yang terbatas dalam menghilangkan bahan organik. Salah satu solusi keterbatasan tersebut dikombinasi dengan karbon aktif (Hidalgo & Murcia, 2021). Absorpsi adalah metode penting untuk menghilangkan zat-zat kimia terlarut di dalam air dapat dihilangkan melalui penyerapan oleh bahan tertentu.…”

Pada saat ini kebutuhan akan pengolahan air untuk mendukung perkembangan ekonomi dan kesehatan dialami oleh pondok pesantren. Pondok Pesantren Nurul Hijrah Jorong Kalimantan Selatan menggunakan air dari sumur bor air gambut untuk memenuhi kebutuhan. Air tersebut merupakan air gambut, hal ini disebabkan oleh kondisi daratan di Kalimantan Selatan yang merupakan lahan gambut. Berbagai masalah penggunaan air saat ini diantaranya kebersihan dan kesehatan, seperti meninggalkan noda coklat hasil endapan serta kondisi gatal-gatal kulit yang dialami santri, dengan jumlah lebih 300 santri dan jamaah di Pondok Pesantren Nurul Hijrah Jorong. Hal ini masih merupakan masalah yang harusnya tersolusikan, maka tujuan pengabdian masyarakat ini yaitu upaya untuk meningkatkan kualitas air sumur bor air gambut tersebut sesuai baku mutu air bersih. Metode yang dilakukan yaitu proses pengolahan air yang menggabungkan proses filtrasi, absorpsi dan ultrafiltrasi dengan sistem single flow ultrafiltrasi. Hasil evaluasi berdasarkan laboratorium menunjukkan bahwa terjadi penurunan yaitu nilai jumlah zat terlarut (total dissolved solid/TDS) 0,2%, kekeruhan 25,8%, warna air 63,6%, nitrat 95%, coliform 49,8% serta peningkatan nilai keasaman 2%. Hasil produksi air bersih memiliki kapasitas besar hingga 2400 lt. 80% perwakilan santri dan ustad pengelola mendapatkan pengetahuan dan keterampilan tentang penggunaan dan perawatan teknologi pengolahan air ini. At this time, Islamic boarding schools experience the need for water treatment to support economic development and health. The Nurul Hijrah Islamic Boarding School in Jorong, South Kalimantan, uses water from drilled peat wells to meet its needs. This water is peat water caused by the condition of the land in South Kalimantan, which is peat land. Various problems with water use today include cleanliness and health, such as leaving brown stains from sediment and itchy skin conditions experienced by students, with more than 300 students and congregations at the Nurul Hijrah Jorong Islamic Boarding School. So, this community service aims to improve the water quality of drilled peat wells according to clean water quality standards. The method used is a water treatment process that combines filtration, absorption, and ultrafiltration processes with a single-flow ultrafiltration system. The results of the evaluation based on the laboratory showed that there was a decrease in the value of the total dissolved solids (TDS) 0.2%, turbidity 25.8%, watercolor 63.6%, nitrate 95%, coliform 49.8% and increased acidity value 2%. Besides, clean water production has a large capacity of up to 2400 lt, and the management ustad has knowledge and skills of up to.

“…Ultrafiltration processes have been extensively employed not only for the purpose of rejecting Dissolved Organic Matter, but also for the elimination of heavy metals such as Cd2+, Co2+, Ni2+, and Cu2+, with a 96% allowance. The utilization of activated carbon (AC) powder in conjunction with ultrafiltration membranes for the removal of organic compounds in drinking water treatment has been investigated [Hidalgo & Murcia, 2021]. Consequently, further research utilizing alternative filtration methods is necessary to eliminate the presence of natural organic matter, as well as other natural and anthropogenic pollutants in peat water.…”

Peatlands have ecological importance, human activities and climate change have created various environmental challenges for peatlands. One of the problems with peatlands is the degression in the quality of peat water, which has a negative impact on ecology and human health as well as the welfare of local communities who depend on peat water as a source of clean water. The problem of peat water processing lies in the need for large capacity, ease of maintenance, and water quality that meets standard criteria. The aim of this research is to evaluate the combination of filtration, absorption, and double flow ultrafiltration techniques, and compare them with single flow ultrafiltration techniques for treating peat water in the South Kalimantan region of Indonesia by looking at the amount of production and quality of water treatment results. This research proposes dual flow ultrafiltration as a solution for treating peat water on a large scale up to 2 times and results in better water quality than single flow ultrafiltration treatment. This is indicated by the percentage difference in TDS reduction of 19.5%, color of 23.1%, nitrite of 37.8%, and manganese of 69%. However, the dual flow ultrafiltration method still has a higher turbidity of around 60.65% and nitrate of about 15%. However, these water treatment results are still standardized by the Indonesia Minister of Health PERMENKES No.492/MENKES/PER/IV/2010.
