What Apria Systems does

Apria Systems S.L. is a privately held Spanish engineering and technology company founded in 2011 and headquartered in El Astillero, Cantabria, that designs and manufactures custom-built equipment for membrane separation processes and oxidation/reduction (photochemical, electrochemical, photoelectrochemical, photothermochemical) applications. The company addresses environmental challenges including stream separation and purification, sustainable energy production, and waste valorization, serving three primary customer segments: research institutions and universities (laboratory and pilot-scale equipment), the aquaculture industry (notably the proprietary ELOXIRAS® system for treatment and reuse of seawater and brackish water in recirculating aquaculture systems, or RAS), and industrial clients requiring custom water treatment, gas processing, and chemical production equipment.

The product portfolio spans membrane technologies (microfiltration through reverse osmosis, electrodialysis, forward and pressure-retarded osmosis, membrane distillation), LED-based photochemistry reactors, configurable electrochemical cells with selectable electrode materials (BDD, IrO2, carbon felt, PtOx, Ni, etc.), and the ELOXIRAS® MINI/HYBRID/LOGISTIC product family. The MultiCell platform represents a modular add-on enabling interchange of up to five process technologies within a single device. All equipment is custom-engineered and manufactured at the Cantabria facility, then delivered globally to 140+ clients across more than 15 countries on four continents, with notable deployments at Los Alamos National Laboratory, CIEMAT, multiple Spanish and European universities, and aquaculture operators in Spain, UK, Canada, Chile, and Norway.

Revenue is generated through one-time custom equipment sales, R&D+i consulting and engineering services, and ELOXIRAS® hardware sales, supplemented by participation as lead or core partner in European and regional funded projects (Horizon Europe, LIFE, MSCA, PERTE Hidrógeno, COST). Since founding, the company has executed over 40 R&D+i projects with cumulative technology investment exceeding EUR 8 million, supported by a 22-person multidisciplinary team and certified to ISO 9001, ISO 14001, and UNE 166002 standards. Apria holds a registered trademark for ELOXIRAS® and operates as a sales-led, direct-engagement business with sales engineers managing the full project lifecycle from specification through commissioning.

Broad incumbents

• Pall Corporation: Major industrial filtration and membrane separation company with microfiltration, ultrafiltration and crossflow systems. Comparable in membrane-technology equipment for water and process separation, though Pall is far larger and serves standard industrial OEM customers.
• Evoqua Water Technologies: Provider of water and wastewater treatment systems including electrochemical, membrane and disinfection solutions. Comparable product overlap in industrial water treatment with broader scale and a stronger North American installed base.
• Veolia Water Technologies (Suez WTS): Global water-treatment incumbent offering membrane, desalination and electrochemical solutions at industrial and municipal scale. Directly comparable in water-treatment focus but vastly larger and broader in portfolio than Apria's custom-engineered membrane/electrochemistry equipment.
• Aqua-Aerobic Systems: US provider of advanced aeration and water-treatment systems including membrane bioreactors. Overlapping customer base (industrial/aquaculture-adjacent water treatment) but more standardized product portfolio versus Apria's bespoke approach.

Regional players

• AKVA Group: Leading aquaculture technology supplier offering RAS components and water-treatment solutions. Comparable as a buyer of aquaculture water-treatment technology and a potential channel/distribution partner for ELOXIRAS in Nordic/Northern European RAS markets.

Direct peers

• Lenntech: Dutch water-treatment specialist supplying custom membrane and desalination equipment (including RO and ultrafiltration) to research and industrial customers. Closely comparable in serving universities and custom-engineering membrane rigs at lab/pilot/industrial scale.

Closest direct competitor to Apria in custom electrochemical cell design and electrode selection for advanced oxidation.

Others

• Fraunhofer IGB / Institute for Interfacial Process Engineering: European applied-research institute developing membrane and photochemistry/electrochemistry technologies. Comparable as a partner in EU-funded consortia (similar role Apria plays), though it is non-commercial and not a direct commercial competitor.

Emerging players

• Condias: German specialist in boron-doped diamond (BDD) electrodes and electrochemical oxidation systems for water treatment and disinfection. Highly comparable technology focus to Apria's electrochemical cells and ELOXIRAS-style advanced oxidation approach.
