Ozonetech

What Ozonetech does

Ozonetech is a Swedish environmental-technology company that designs, manufactures, and commissions ozone generation and advanced oxidation systems for industrial and municipal air and water treatment. Operating as a brand within the privately held Mellifiq Group (headquartered in Hägersten/Stockholm), Ozonetech was established in the early 1990s and has accumulated over 30 years of domain experience, with installations in 46 countries across all six continents.

The company's product architecture is anchored in a patented corona discharge process for ozone generation, supplemented by proprietary HELS (High Efficiency Low Energy System) electrode-free technology and the SMARTOZONE design concept. The portfolio spans ozone generators (ICT, DCT, ACT, and FTX series), PSA oxygen generators and concentrators (Topaz series, up to 95.5% O2), ozone destructors, mixing devices, and sensors/monitors. At the solutions layer, the RENA family covers air treatment (RENA Pro), tailored water systems (RENA Tellus), advanced oxidation for complex wastewater and pharmaceutical residues (RENA Vitro), water purification (RENA Vivo), and commercial kitchen exhaust (RENA Kitchen Solutions); the Nodora brand extends into modular high-airflow odor reduction. Supporting services include CFD simulation, air/odor analysis, and tailored pilot projects.

Ozonetech generates revenue primarily through hardware sales of ozone generators, oxygen systems, and turn-key RENA solutions, with an overlay of professional services (CFD simulation, pilot projects, system design). Go-to-market is direct enterprise field sales with a quote-based, consultative model targeting industrial plants, municipal water utilities, pharmaceutical companies, food and beverage producers, biogas operators, and large commercial real estate/facilities customers (with a documented McDonald's Kivikko Finland case study in commercial kitchen exhaust). The company is private, with no disclosed external funding, no listed management team in the source data, and no acquisitions or restructuring events reported.

Direct peers

• Wedeco (Xylem): Wedeco, now part of Xylem, is a direct competitor manufacturing ozone generators and UV systems for municipal drinking water, industrial process water, and wastewater. Both Ozonetech and Wedeco sell into the same industrial/municipal water treatment use cases with overlapping buyer personas.
• Ozonia (Suez): Ozonia, the ozone-generation brand of Suez, manufactures large-scale corona and UV ozone systems for municipal drinking water and industrial process water — a direct competitor to Ozonetech's RENA Vitro AOP and RENA Vivo product lines and the most direct enterprise-scale ozone peer.
• ProMinent Group: ProMinent manufactures ozone generation systems, metering pumps, and complete water treatment solutions for industrial and municipal applications. Direct competitor to Ozonetech on ozone dosing and disinfection hardware, particularly in pharmaceutical and food & beverage water treatment.

Emerging players

• BIO-UV Group: BIO-UV manufactures UV-based disinfection and ozone/UV reactors for industrial and commercial water treatment, including aquaculture and pools. Overlapping customer segments in disinfection and water sanitization make it a credible emerging substitute for some Ozonetech use cases.
• De Nora: De Nora manufactures electrodes, electrochemical cells, and water treatment systems including disinfection and oxidation technologies that compete with ozonation for industrial and municipal water treatment customers.

Broad incumbents

• BWT (Best Water Technology): BWT is a broad European water technology incumbent with industrial and commercial water treatment systems (filtration, disinfection, process water). BWT competes for the same municipal and commercial buyer RFPs as Ozonetech and represents the broader-incumbent threat to a niche vendor.
• Evoqua Water Technologies (now part of Xylem): Evoqua, acquired by Xylem in 2023, supplied industrial water treatment systems with overlap on ozone and AOP technologies. The combined Xylem + Wedeco + Evoqua entity is the broad incumbent most likely to bundle ozone as one option among many competing solutions against Ozonetech.
• Mitsubishi Electric (Ozone systems): Mitsubishi Electric manufactures industrial ozone generation systems for water treatment and semiconductor wet bench applications, and competes for large industrial ozonation RFPs against Ozonetech with significantly greater scale and balance sheet.

Regional players

• Lenntech: Lenntech is a Dutch water treatment systems integrator that designs, supplies, and services ozone generators and complete treatment plants across Europe and globally. Comparable product portfolio and application breadth with similar enterprise/municipal customer base.
• Ecozone (ozone systems): Ecozone is a Swedish-based Nordic manufacturer of ozone water treatment and air purification systems focused on commercial and light industrial applications — a regional peer operating in Ozonetech's home market with similar product categories and target use cases.
