PuriTech

What PuriTech does

PuriTech Bvba is a Belgian engineering company founded in 1996 and headquartered in Dessel/Mol, Belgium, specializing in liquid adsorption separation and ion exchange technology. The company is a subsidiary of Sunresin (SepLite) and operates with a lean 1–10 employee organization. Its core offering is the patented ION-IX continuous counter-current ion exchange (CCIX) system, which uses a single multiport distribution valve to continuously route flow streams across multiple resin cells operating in adsorption, regeneration, and rinsing cycles—replacing conventional multi-valve batch architectures. This architecture delivers reduced chemical and resin consumption, smaller plant footprints, lower capex/opex, and over 90% prefabrication in project execution.

The company serves industrial customers across four primary verticals: water treatment (softening, demineralisation, nitrate/ammonia removal, boiler feed, and contaminant removal including arsenic, boron, radium); hydrometallurgy and metal recovery (lithium extraction, nickel/cobalt purification, copper, zinc, gold, uranium, germanium, molybdenum); food processing (sugar syrup deashing, color removal, fructose/glucose separation, lysine purification, whey/lactose); and chemical applications (amine removal, ethylene glycol deashing, potassium nitrate, biodiesel, iohexol). Notable reference projects include the largest-ever ION-IX lysine unit for Meihua (China) and the first geothermal lithium demo plant in the UK for GEL (Cornwall, 2026).

PuriTech monetizes through custom plant engineering and construction (project-based), pilot testing and mobile treatment unit rentals (usage-based, weeks to years), backup/rental equipment supply, and process technology licensing. It distributes via direct enterprise field sales supplemented by a curated global partner and agent network (ILiAD, ACWa, Kurita America/Tonka Water, Marston Hydro-Met, Chemical Systems Technologies, BODA, Relex Process Consultancy) covering the UK, North America, and other regions.
