What OxyMem does
OxyMem, founded in 2013 as a spin-out from University College Dublin's Biofilm Engineering Laboratory, develops and commercialises Membrane Aerated Biofilm Reactor (MABR) modules for municipal and industrial wastewater treatment. The technology uses dense, pore-free PDMS (silicone) hollow-fibre membranes through which oxygen diffuses directly into a biofilm on the membrane surface, eliminating the bubble-diffusion step used in conventional activated sludge. Each stainless-steel module houses approximately 1.6 million metres of microbore tubing delivering up to 2,200 m² of membrane surface area, with a patented biofilm control system that periodically removes excess growth via coarse-bubble scouring. Configurations include OxyFAS (IFAS drop-in modules for retrofitting existing tanks without draining), OxyFILM (standalone packaged biofilm phase), the Generation 4 module, and lab/mini units used for trials.
The company's commercial offering is anchored in drop-in hardware sales to enterprise wastewater operators, supported by multi-year extended warranties (10 years for municipal, 5 years for industrial customers) that introduce a recurring-revenue component. Pricing is quote-based on plant requirements and is not publicly disclosed, and the go-to-market relies on direct enterprise field sales supplemented by regional channel partners such as Aquafy Water Technologies and Island Water Technologies in Canada. End customers include major utilities such as Severn Trent (UK), Anglian Water (UK), Sabesp (Brazil), Vandcenter Syd and Aarhus Vand (Denmark), alongside engineering firms (Jacobs) and industrial operators including a Spanish beverage producer and a Dow-linked Brazilian lagoon upgrade. Since commercial launch in 2014, more than 20 MABR systems have been deployed across the UK, Ireland, Canada, Sweden, Spain, Saudi Arabia, Brazil, China, Denmark, New Zealand, Japan and the Netherlands.
OxyMem was acquired by DuPont in 2019 and now operates as part of DuPont Water Solutions, with DuPont announcing a multimillion-euro transformation of the Athlone manufacturing facility in March 2022. The company is headquartered in Athlone, Ireland, operates a membrane production line in Leixlip, and currently employs between 51 and 100 people. Revenue is not publicly disclosed and the US market is currently not served following a 2016 competitor patent dispute.

OxyMem product offering
Product offeringCore offering
OxyMem designs, manufactures, and sells Membrane Aerated Biofilm Reactor (MABR) modules for municipal and industrial wastewater treatment plants. The modules use dense gas-permeable PDMS (silicone) hollow fiber membranes that deliver bubble-less oxygen transfer to biofilm, enabling up to 75% energy savings and simultaneous nitrification-denitrification. Products are offered in drop-in IFAS (OxyFAS) and packaged (OxyFILM) configurations for capacity upgrades in existing activated sludge tanks.
Product overview
OxyMem offers a modular MABR (Membrane Aerated Biofilm Reactor) platform for wastewater treatment. The core MABR technology uses gas-permeable hollow fiber membranes to support biofilm growth, enabling bubble-less oxygen transfer and simultaneous nitrification-denitrification. The product portfolio consists of the MABR platform with two main deployment configurations: OxyFAS (IFAS drop-in modules) for retrofitting existing activated sludge tanks, and OxyFILM for standalone packaged applications. Additional offerings include Generation 4 Modules with specified physical dimensions, OxyLab and Mini MABR units for testing, and a proprietary Design Tool for system sizing. The technology is protected by multiple patents covering biofilm control and membrane design.

OxyMem competitors and assessment
Company assessmentEmerging players
- Aqwise: Israel-based provider of biofilm carriers and MBBR/IFAS solutions for municipal and industrial wastewater treatment plant upgrades. Comparable to OxyMem's biofilm-based approach for capacity expansion in existing tanks, though focused primarily on attached-growth carriers rather than membrane aeration.
- HUBER Technology: Germany-based manufacturer of wastewater treatment equipment including fine bubble aeration systems, MBR modules, and biological treatment solutions for municipal and industrial customers. Comparable to OxyMem in providing drop-in aeration and biological treatment modules for retrofit applications.
Direct peers
- Organica Water: Hungarian-headquartered provider of Fixed-Biofilm Activated Sludge (FAS) and Activated Biofilm Reactor (ABR) technology for municipal and industrial wastewater treatment. Most direct MABR/biofilm-based competitor to OxyMem, also retrofitting activated sludge tanks with biofilm carrier modules for simultaneous nitrification-denitrification.
- Ovivo: Canada-based pure-play water and wastewater treatment equipment manufacturer serving municipal and industrial customers with membrane bioreactors (MBR), aeration, and biological treatment systems. Comparable in targeting activated sludge tank upgrades and energy-efficient aerobic treatment, with similar enterprise field-sales motion to OxyMem.
- Fluence Corporation: Provider of decentralized and packaged wastewater treatment plants, MABR modules (originally licensed Fluence MABR technology), and water reuse solutions for municipal and industrial clients. Most directly comparable to OxyMem in MABR product offering and decentralized/industrial target segments, including beverage/food and smaller municipal applications.
- Aqua-Aerobic Systems: US-based manufacturer of biological and aeration equipment for municipal and industrial wastewater treatment, including MBBR/IFAS systems and aerobic biological treatment processes. Overlaps OxyMem in drop-in biofilm/aeration module retrofits for activated sludge plants and offers comparable energy-efficiency-focused retrofit solutions.
Broad incumbents
- Kurita Water Industries: Japanese industrial water and wastewater treatment solutions provider serving semiconductor, pharmaceutical, and industrial customers with biological treatment and process water systems. Overlaps with OxyMem's industrial process wastewater segment (food & beverage, pharma, refining) and offers competing biofilm and aeration upgrades.
- Veolia Water Technologies: Global water and wastewater treatment technology and services arm of Veolia, offering a broad portfolio including biofilm (AnoxKaldnes MBBR/IFAS) and municipal/industrial plant upgrade solutions. Comparable in serving the same municipal and industrial wastewater customers with biofilm and aeration technologies, but as part of a much wider water-treatment portfolio.
- SUEZ Water Technologies & Solutions: Global water and wastewater treatment solutions provider, including biofilm, MBR, and aerated treatment systems deployed at municipal and industrial sites. Overlaps with OxyMem on municipal nutrient removal and industrial process water, though as part of a full water services platform rather than a focused MABR specialist.
- Xylem (Evoqua): Global water technology company that acquired Evoqua Water Technologies in 2023, offering a broad portfolio spanning aeration, MBR, disinfection, and biofilm-based wastewater treatment (e.g., SANITAIRE, Wedeco). Competes with OxyMem in municipal and industrial water reuse, nutrient removal, and energy-efficient plant upgrades, though from a much broader portfolio and global sales scale.
