What SFC Umwelttechnik does

SFC Umwelttechnik GmbH is a privately held Austrian environmental-technology company founded in 1993 and headquartered in Salzburg, specializing in water and wastewater treatment for municipal, industrial, healthcare, and remote/off-grid applications. The company's core technology stack rests on three proprietary platforms: C-MEM™ ultrafiltration using PFAS-free HDPE hollow-fiber membranes with a 20 nm pore size (delivered as Membraloop™, C-MEM™ Zero, MembraConnect™, and Sub-UF modules); C-ION™ non-thermal plasma oxidation (commercialized as PlasmaConnect™) using dielectric barrier discharge to generate reactive oxygen species for trace substance, manganese, arsenic, and bulking-sludge control; and C-TECH™ / MBBR biological treatment for simultaneous nitrification, denitrification, and biological phosphorus removal. Over 30+ years the company has delivered 1,750+ projects and manufactured 15,000+ UF modules, with reference installations ranging from 100-population-equivalent mountain huts to a 1.2 million-PE plant in Malaysia.

The business model is project-based and enterprise-oriented, combining direct equipment sales (hardware), engineering and consulting (professional services), full EPC turnkey delivery (managed services), and recurring service and maintenance contracts. Pricing is project-specific and not publicly disclosed. SFC sells primarily through direct enterprise sales, supported by wholly-owned subsidiaries in India (SFC Environmental Technologies Ltd, Navi Mumbai) and the Czech Republic (SFC Ekotechnika s.r.o.), representation in Mexico via Aventia, and a presence in Thailand. Customers are diversified across municipalities and water utilities (Roßleithen, Fuschl, Zell am Ziller, Faistenau), industrial verticals including biomass heating (Eneco Utrecht, Hasslacher Sachsenburg), dairy (Berglandmilch), automotive (Tenneco), paper (Essity Santiago), and sawmills (Donausäge Enns), as well as healthcare facilities (Mittaphab Hospital Laos, Angola hospitals via VAMED/Uniha) and commercial/residential users (Bad Tölz, Obama Sports Complex). The company holds ISO 9001 certification from TÜV and NSF 350 certification for its greywater recycling system.

Core offering

SFC Umwelttechnik designs, manufactures, and delivers water and wastewater treatment solutions built on proprietary ultrafiltration membrane technology (C-MEM™), non-thermal plasma oxidation (C-ION™/PlasmaConnect™), and biological treatment (C-TECH™, MBBR, MBR). The company provides turnkey EPC project delivery from feasibility through commissioning for municipal water utilities, industrial facilities (paper, food, biomass, automotive), and healthcare providers, plus branded ready-to-use ultrafiltration and oxidation units for decentralized and remote applications.

Product overview

SFC Umwelttechnik offers a comprehensive portfolio of water treatment technologies and products built around three core technology platforms — C-MEM™ ultrafiltration (HDPE hollow fibre membranes, ~20 nm pore size), C-ION™ non-thermal plasma oxidation, and C-TECH™/MBBR biological treatment. The branded product lines include Membraloop™ (flexible portable ultrafilter), C-MEM™ Zero (gravity/pump-operated ultrafilter), MembraConnect™ (compact modular ultrafiltration unit), PlasmaConnect™ (NTP oxidation system), and Sub-UF Module (immersed ultrafiltration). These are complemented by licensed/complementary products AQUALOOP™ (grey water recycling system), Yucheon Disc Filter, and Wendewolf® (solar sludge drying). The offering spans drinking water treatment, wastewater treatment, and water reuse, serving municipal, industrial, and remote/off-grid applications.

Broad incumbents

• Pentair plc: Pentair supplies residential, commercial and industrial water-treatment and filtration equipment (X-Flow UF membranes), competing with SFC at the industrial/light-municipal end of the same UF and water-reuse markets.
• Xylem Inc. Xylem's Water Solutions & Services offers UF/MBR systems, biological treatment and smart water networks for municipal and industrial customers — a broad incumbent competitor to SFC across the same EPC turnkey and equipment-supply use cases.
• Veolia Water Technologies: Veolia operates one of the world's largest water-technology EPC and services portfolios, covering UF/MBR, biological treatment, oxidation and reuse — overlapping heavily with SFC's municipal and industrial offering but at vastly greater scale and geographic reach.
• Suez Water Technologies & Solutions: Suez supplies UF/MBR membranes (ZeeWeed), biological reactors and oxidation systems globally — directly overlapping SFC's product stack and competing on the same municipal and industrial tenders, but as part of a much broader utility and services portfolio.

Direct peers

• LG Water Solutions: LG Water Solutions supplies NanoH₂O™ RO and UF membranes for municipal and industrial water treatment, with comparable hollow-fibre UF/MBR offerings and an overlapping customer base in industrial wastewater and drinking water projects.
• Microdyn-Nadir (MANN+HUMMEL): Microdyn-Nadir manufactures UF, MBR and specialty membranes for municipal and industrial water treatment — directly comparable to SFC's C-MEM™ UF and Sub-UF modules, and similarly serves municipal and industrial customers across DACH and globally.
• Toray Membrane (Toray Industries): Toray's water-treatment division produces PVDF and PES hollow-fibre UF/MBR membranes used in municipal drinking water and industrial reuse — a major direct competitor to SFC's C-MEM™ UF and MBR plants serving overlapping municipal and industrial customers.
• inge GmbH (DuPont Water Solutions): inge GmbH (now part of DuPont) develops Multibore® hollow-fibre ultrafiltration membranes for drinking water and wastewater — the closest direct peer to SFC's C-MEM™ HDPE UF technology in both product architecture (hollow fibre, ~20 nm pore size) and target market (municipal drinking water).
• MANN+HUMMEL Water & Fluid Solutions: Following its acquisition of Microdyn-Nadir, MANN+HUMMEL offers an integrated UF/MBR membrane and filtration portfolio for municipal and industrial water — closely paralleling SFC's combination of proprietary UF modules, biological treatment, and EPC delivery.

Emerging players

• Aquaporin A/S: Aquaporin develops biomimetic hollow-fibre UF/forward-osmosis membranes for water reuse and industrial treatment. It targets overlapping applications (drinking water, industrial reuse, point-of-use) with novel membrane chemistry, making it an emerging competitor in the niches where SFC positions Membraloop™ and C-MEM™ Zero.
