What Jotem Waterbehandeling does

Jotem Waterbehandeling (legal entity Jotem Water Solutions B.V.) is a Netherlands-based, privately held engineering company founded in 1965 that designs, builds, commissions, and services custom industrial water treatment installations. Headquartered in Vriezenveen with approximately 40 employees, the company combines process engineering, mechanical engineering, and automation disciplines under a single point of contact and offers coverage across 35+ technologies, including membrane filtration (microfiltration, ultrafiltration, nanofiltration, reverse osmosis), ion exchange, electrodeionisation, activated carbon and multimedia filtration, UV disinfection, degassing, advanced oxidation processes, and the proprietary BODAC biological filtration system. Its portfolio spans the Hydro Pilots line of custom pilot systems and a branded Hydro Products line (BluElephant, HydroCube, HydroNext, WaterMiracle, Power up your Poop) addressing industrial process water, pharmaceutical- and food-grade water, emergency and humanitarian water supply, and decentralized wastewater reuse, supported by 24/7 service & maintenance contracts and a Hydro Rentals mobile-unit fleet.

The business generates revenue primarily through one-time project sales of engineered water treatment systems, supplemented by recurring service & maintenance contracts and equipment rental. Pricing is quote-based and not publicly disclosed, with multi-year service contracts in place. Customers are enterprise and institutional: industrial manufacturers (Qemetica, Pentair, NEDRI Spanstaal, FrieslandCampina, AEB Amsterdam), water utilities (Vitens), research institutions (University of Twente, KAUST), government (Dutch Ministry of Defence, Forteiland Pampus), and innovation consortia (NieuWater, BlueCycle, NX Filtration). Distribution is direct enterprise field sales, with co-development partnerships supplying the technology layer (e.g., Van Remmen UV, University of Twente, Waterstromen, Nijhuis Saur Industries).

Jotem's competitive positioning is built on 60 years of domain expertise, an integrated multi-discipline engineering team, and proprietary software (ASMBLR) and pilot-platform IP (Mexpert/Mexplorer/Hydro Pilots), with selected AI-driven process control capability via the SMARTIER collaboration. The company is family/management-owned, has never raised external capital, and is investing in a new production hall at its Vriezenveen site in 2025 to support continued growth.
