Powerful Water Purification Technology

Roxia Plasma Oxidizer™ is an effective non-thermal plasma technology for industrial water purification. Plasma generated oxidants effectively remove colour, odour and organic residues while disinfecting the water. Roxia Plasma Oxidizer (RPO) is the superb water purification system alternative to ozone, UV and chemical treatment.

Roxia Plasma Oxidizer Replaces Treatment Chemicals With Plasma

Roxia Plasma Oxidizer (RPO) is unique industrial water treatment technology as it uses non-thermal plasma in direct contact with water to destroy dissolved organic pollutants. Purified water can now be a result of completely chemical-free process. RPO is considered to be the paradigm shift in oxidative water treatment and industrial water purification. It eliminates the need for transportation, storage and handling of risky disinfection chemicals, thereby mitigating costs and environmental risks. Roxia Plasma Oxidizer is safer, more economical and environmentally friendlier solution.

What can Roxia Plasma Oxidizer do?

Disinfect water

Destroy organic pollutants

Remove colour and odour

Prevent membrane fouling

Purify plant cooling and process waters

Remove pharmaceutical residues

How does Roxia Plasma Oxidizer work?

Treated water runs through non-thermal plasma field

This creates strong oxidants from the treated water and surrounding air

The oxidants then destroy pollutants and disinfect the water with a lasting effect


Roxia Plasma Oxidizer (RPO) turns direct plasma oxidation into an industrial product.

Roxia Plasma Oxidizer is also suitable for other operations and processes. Want to know more?

Gained value from RPO against conventional systems

Ozone systems

Your value from RPO:

  • Lower energy consumption
  • More powerful oxidation for the money

UV systems

Your value from RPO:

  • Robust design: only stainless steel is in contact with the water, no moving parts -> low maintenance
  • Insensitive towards turbidity
  • No UV lamps

Chemical treatment

Your value from RPO:

  • No chemical logistics, storage and use
  • No chlorinated byproducts
  • Only electricity is used
  • Reduced safety protocols

ProjectsScaling up the Roxia Plasma Oxidizer

The project objective is to design a 10-kW Roxia plasma Oxidizer (RPO). This serves to fill a technological gap on organics control in ZLD targets within mining water management, where the technology has been proven extremely efficient.

This activity was funded by the Start-up & SME Booster Programme from the EIT RawMaterials, funded by the EIT, a body of the European Union supported under the Horizon 2020 research and innovation program.

Water protection programme stamp. The City of Lappeenranta and the Centre for Economic Development, Transport and Environment.

ProjectsCleaner hospital wastewaters

Roxia Plasma Oxidizer™ aims to destroy 90-99 % pharmaceutical residues from the hospital wastewaters. With this installation, Roxia is the trailblazer on a global scale as this will be the first-of-a-kind on the planet!

The system will degrade pharmaceuticals before the hospital sewage enters the public sewer network and the concentrations are diluted. Installation to the local Central Hospital in Lappeenranta, Finland, was funded by the City of Lappeenranta and the Centre for Economic Development, Transport and Environment.
