What ClearFox does
ClearFox, the commercial brand of PPU Umwelttechnik GmbH, is a Bayreuth, Germany-based manufacturer of modular and containerized wastewater treatment systems serving municipal, industrial, and decentralized domestic customers in more than 50 countries. The company's technology portfolio spans biological processes (Fixed Bed Biological Reactor, Sequencing Batch Reactor, Membrane Bioreactor), physical separation (Dissolved Air Flotation, lamella clarifiers, screw screens), sludge treatment (thickener, screw press, dewatering bags), and advanced electrochemical oxidation (the ClearFox DiOx line, using boron-doped diamond electrodes to degrade PFAS, 1,4-dioxane, and dyes). ClearFox reports more than 40,000 installed treatment systems and a cumulative daily treatment capacity of 25 million liters. All systems are designed and manufactured in-house in Germany and offered as containerized plug-and-play plants, packaged systems, or equipment kits for retrofit into existing tanks.
The business model blends one-time equipment sales — both custom-engineered projects and standardized packaged units — with a recurring rental and leasing fleet of containerized equipment and ongoing service contracts covering installation, commissioning, operations, and maintenance. Pricing is project-based in EUR with defined service rates (EUR 45-200 per hour for technical staff, EUR 1,250 per day on-site, plus travel and accommodation). Go-to-market is hybrid: direct enterprise field sales for large industrial and municipal tenders, complemented by a global network of regional sales, installation, and OEM partners including euTecK, Waterplan System, Abwassertechnik Schubert, AquaVerde, Marco Glück, Köster-Bauservice, Klärtechnik Garsoffke, Aquaplast (licensed tank supply), and Breizho (French distributor). The company is a privately held German GmbH with no evidence of external venture or private equity ownership, managed by Dipl.Ing. Wolfgang Pöhnl, and holds DIN EN ISO 9001, DIN EN ISO 14001, and EN12566-3 certifications.
