The industrial effluent presented a high saline concentration, including sodium chloride, calcium carbonate, calcium sulfates, and magnesium. The effluent was treated using a system of reverse osmosis (RO) and a post-treatment process consisting of ion exchange resins (IEXRs). The RO was accompanied by the addition of a hexametaphosphate dose (2, 6, and 10 mg\/L) as an antiscalant to avoid the RO membrane scaling by minerals. In turn, IEXRs were used for water deionization to produce ultrapure water with a reduced concentration of monovalent ions. The antiscalant dose was 6 mg\/L, producing clean water from RO permeates with an efficiency of 65\u201370%. The brine from RO was projected for its reuse in food industry processes. The clean water quality from RO showed 20% total dissolved solids (TDS) removal (equivalent to salts). The antiscalant inhibited the formation of calcium salt incrustation &gt; 200 mg\/L, showing low fouling. In turn, anionic resins removed 99.8% of chloride ions, whereas the monovalent salts were removed by a mix of cationic\u2013anionic resin, producing ultrapure water with electrical conductivity &lt; 3.3 \u00b5S\/cm. The cost of ultrapure water production was 2.62 USD\/m3.<\/jats:p>","DOI":"10.3390\/membranes15040116","type":"journal-article","created":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T20:43:17Z","timestamp":1745440997000},"page":"116","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Ultrapure Water Production by a Saline Industrial Effluent Treatment"],"prefix":"10.3390","volume":"15","author":[{"given":"Adriana Hern\u00e1ndez","family":"Miraflores","sequence":"first","affiliation":[{"name":"Tecnol\u00f3gico Nacional de M\u00e9xico, Instituto Tecnol\u00f3gico de Toluca, Av.
