“…Pengoperaisan unit IE fleksibel (skala kecil dan besar) dan relatif mudah, tetapi butuh energi lebih untuk proses pumping dan mixing dan butuh larutan regenerasi banyak untuk mendukung aktivitas resin [57][58]. Larutan regenerasi terpakai menjadi brine berbahaya bagi lingkungan dan perlu diolah sebelum dibuang [59].…”

Print) F35 Abstrak-Kebutuhan air minum dipenuhi dengan pengolahan air minum menggunakan air baku berupa air permukaan dan air tanah. Salah satu pencemar utama air baku adalah amonia, yang dapat menyebabkan berbagai masalah, baik bagi kehidupan perairan, kesehatan manusia, dan kinerja pengolahan air minum. Terdapat 5 teknologi pengolahan air yang dapat menyisihkan amonia secara efektif, yaitu: (1) proses biologis, (2) breakpoint chlorination (BPC), (3) filtrasi membran reverse osmosis (RO), (4) proses ion exchange (IE), dan (5) proses air stripping. Proses biologis dan BPC dinilai sebagai 2 teknologi paling efisien dalam penyisihan amonia dengan keefektifannya relatif tinggi dan biaya relatif murah. Proses RO dan IE dapat menyisihkan amonia dalam bentuk amonium secara efektif, tetapi butuh biaya lebih tinggi. Penyisihan amonia dengan proses air stripping efektif pada konsentrasi tinggi yang tidak ditemukan pada air baku. Penyisihan amonia pada pengolahan air minum konvensional dinilai tidak efektif. Koagulan bermuatan positif tidak bereaksi dengan amonia berbentuk amonium dan unit filtrasi konvensional dengan media inert utamanya menyisihkan partikel tersuspensi. Klorin dan ozon adalah 2 desinfektan yang dapat menyisihkan amonia, tetapi ozon bersifat tidak stabil sehingga jarang digunakan. Klorin dapat menyisihkan amonia secara efektif, tetapi dosis klorin berlebihan dapat membentuk produk sampingan desinfeksi yang berbahaya.

“…The process of ion exchange may be used to remove potential scale forming ions as a pre-treatment or as a stand-alone desalination technique, although this option is usually limited to the water with salinity values of 3000 mg/l. Ion exchange can be used in a variety of bed configurations and with various resin types but the regeneration of the loaded resin is a critical component of the process and the required reagents are often expensive (Liu et al, 2021). GYP-CIX is a low cost ion-exchange technology for the removal of sulfate, calcium, magnesium and other ions from water (Öztürk and Ekmekçi, 2020).…”

The successful acid mine drainage (AMD) treatment needs site-specific installation and implementation, as well as the deployment of technology that is compatible with the pollutants contained in the AMD. If key by-products of the AMD can be recovered, the financial sustainability of the AMD remediation method may be greatly improved. Additional research into novel and innovative solutions is necessary to advance in this direction. To accomplish this, it is necessary to have a complete awareness of current remediation technologies that are available and accessible. Active physical treatment methods such as ion exchange, adsorption, electrochemistry, and membrane techniques were examined in this article. Membrane technology excels in terms of ease of use, versatility, and environmental effect but produces brine streams the management of which remains vital for future adoption of the technology. Liquid membranes (LM), Micellar Enhanced Ultra-Filtration (MEUF), and Polyelectrolyte Enhanced Ultra-Filtration (PEUF) are all innovative membrane technologies that may provide some possibilities for metal recovery from chemical sludge and/or brine streams. Electrochemical technologies are considered an attractive alternative for AMD treatment, because they require only electricity as a consumable and can treat AMD to high standards by removing metals via (co)precipitation and sulfate via ionic migration (when an anion-exchange membrane is used in the configuration), while producing significantly less sludge. However, the accepted shortcomings include membrane/electrode fouling produced by (co)precipitates on the active surfaces necessary for the process, a lack of understanding regarding the effective scaling up to industrial scale, and the relatively expensive capital expenditure (CAPEX) required. The removal of heavy metals from AMD effluents by adsorption has a number of technical and environmental benefits, including high efficiency, and environmental friendliness. Despite its benefits, this technique has certain hurdles, such as the production process for low-cost adsorbents.

“…Conventional treatment of nitrate polluted water requires in most cases the implementation of physical separation technologies (i.e., ionic exchange, reverse osmosis) that generate undesired nitrate-rich brines (Amma and Ashraf, 2020;Liu et al, 2021). Other alternatives consider delicate biologic anammox treatment that requires specialized management and has a large physical footprint, both factors limiting widespread utilization in decentralized settings (Abdelfattah et al, 2020;Crittenden et al, 2012).…”
