Hydrotech

What Hydrotech does

Hydrotech, headquartered in Vellinge, Sweden, designs, manufactures, and sells mechanical water filtration systems including disc, drum, belt, and cloth filters. Founded in 1984 and operating as a brand and business unit of Veolia Water Technologies since its 2004 acquisition, the company produces all filters at its Swedish facility and holds multiple patents covering panel geometry (ALPHAFLEX), particle guidance (PAGUS), interchangeable panel access (WHIP), spray nozzle design, and high-pressure cleaning (HPC). Its portfolio spans more than 500 product variants, with flagship offerings including the HSF2600 Disc Filter, Performance Filter (HPF), Drum Filter Value series (HDFV), the recent Hybrid Disc Filter and Cloth Filter Confidence and Frame Series lines, plus the Nutripack chemical pretreatment modules.

Hydrotech serves three primary verticals: municipal water and wastewater treatment plants, industrial facilities (food and beverage, oil and gas, mining, manufacturing), and aquaculture (including recirculating aquaculture systems, intake and effluent filtration, and sea lice and algae control). The company goes to market through regional sales managers covering the Americas, Industrial, Aquaculture, and Municipal segments, supplemented by a worldwide network of professional service partners that deliver installation, maintenance, spare parts, and process services. Value propositions center on suspended solids removal up to 98%, compact footprint (up to 80% smaller than conventional settlers), reduced water and power consumption, and predictable operating economics, with installed base cited at 13,000+ filter units globally.

Revenue is generated primarily through capital equipment sales of hardware filtration units, augmented by recurring service revenue from original spare parts, equipment upgrades, service packs (e.g., 5-year service kits), and process services, plus digital monitoring via the Hubgrade service. Pricing is quote-based and not publicly disclosed. The company operates from a single headquarters and manufacturing site in Vellinge, Sweden, with approximately 65 dedicated employees, while distribution reaches most major markets through Veolia Water Technologies' partner network across Europe, the Americas, and Asia-Pacific.
