Arviatechnology

Arvia Technology is a tertiary water treatment company that designs, manufactures and supplies systems removing persistent organic contaminants and colour from industrial water and wastewater. Its Nyex range applies a patented advanced oxidation process combining adsorption with electrochemical oxidation in a single step; the adsorption media regenerates in situ during operation, so media does not need to be removed, trucked away or thermally regenerated as with granular activated carbon. The company states the process requires no chemical dosing, produces no toxic sludge, has no moving parts, can be switched on and off as required and uses less energy than conventional advanced oxidation processes because of the adsorption/oxidation combination.

The product line includes Nyex Rosalox (adsorption plus electrochemical oxidation), Nyex Ellenox (electrochemical oxidation without adsorption) and Nyex Florenox, an electrochemical oxidation system aimed at PFAS in water. Systems are offered in a range of sizes, as standalone units or as add-ons integrated into existing treatment trains. Applications marketed by the company include API and micropollutant removal, recalcitrant COD reduction, colour removal, blowdown and RO reject water treatment, water reuse and zero liquid discharge, avoidance of wastewater incineration, point-of-entry and drinking water treatment, and AMR-related treatment. Alongside equipment, Arvia offers water testing, treatability trials and wastewater plant hire, and runs an EPC partner programme.

Sectors served include life sciences (pharma, CDMOs, biotech, biopharma, animal health), specialty and petrochemicals, agrochemicals, industrial manufacturing, battery recycling, textiles, hi-tech and semiconductors, utilities, waste management and aquaculture, where the systems are used to remove sea-lice treatment pesticides, medicines and off-flavours in recirculating aquaculture systems.

Founding story

The company was spun out of the University of Manchester's School of Chemical Engineering and Analytical Science by Nyex inventor and founder Dr Nigel Brown together with Dr Ted Roberts. Dr Brown was working on adsorption technologies and identified the cost and disruption of removing adsorption media from site for regeneration as the central problem; the aim was a technology that regenerated the adsorption material in situ, lowering operating cost and environmental impact. After repeated testing and modification this became the Nyex Rosalox system.

Business model

Arvia designs, manufactures and supplies wastewater treatment equipment and bespoke onsite treatment systems to industrial customers, supported by services such as water testing, treatability trials and wastewater plant hire. It also works through EPC partners.

Sale of wastewater treatment systems and equipment, plus related services including water testing, treatability trials and plant hire.

Traction

Arvia reports systems most successfully applied in pharmaceutical, specialty chemical and agrochemical sectors, and cites customer testimonials including a US pharmaceutical company on API residue treatment and Zestron China, which reported R&D results on removal of 1-Phenoxy-2-propanol and a move toward piloting. Press coverage in July 2018 reported the company securing its first treatment deal in China. An external profile estimated 42 employees and annual revenue of $10M-$25M as of July 2026, while another estimated 21-50 employees and annual revenue of about $179,006; these third-party estimates conflict.

Latest developments

Arvia launched Florenox, an electrochemical oxidation system designed to eliminate PFAS in water, in March 2025. In May 2022 it worked with Lancaster University under the Low Carbon Eco-Innovatory business support programme aimed at reducing carbon emissions and accelerating growth.
