Project overview

  • Annual savings -25 % from wastewater costs
  • Grease and solids no longer block the sewers
  • Sludge is used for biogas production

Customer: Hätälä, Finland’s leading fish producer, fish processing wastewater treatment

Challenge: High wastewater costs (€/m³)

Solution: Water and sludge treatment with remote monitoring, separation of solids, repurposing solids and fatty sludge

Results: Less waste, reduced load to municipal WWTP, 25 % savings in wastewater costs, preventive maintenance

Solids No Longer Block Sewers in Wastewater Treatment Process

Hätälä fish refinery used to channel all their wastewater directly to the municipal wastewater treatment plant. Not only they faced high costs, but they also experienced repeated blockages in the system caused by grease and solids in the sewers.

After careful examination, Roxia and Owatec experts suggested establishing a pre-treatment unit that would separate solids and grease from the wastewater. Per year, Hätälä handles 110 000–130 000 m³ of wastewater and 500–1000 tons of sludge. With these amounts, already separating the solid particles could significantly improve or eliminate the issues.

We created a customised wastewater treatment process. The entire operation is automated and remotely monitored with Roxia Malibu (IIoT platform). This allows Hätälä to save time and focus on their core business. The automation system also monitors pollutant limit values. With only a few clicks, the customer can get instant reports about quality values and treated volume.

Since the installation of the wastewater unit, Hätälä gets two in one: a 25 % reduction of wastewater costs and lower level of impurities. Because solids and grease are now removed from the wastewater, the sewers do not get blocked. What is more, solids and fat sludge are used as biogas feedstock. Recycling such valuable components contributes to better use of resources and reducing the environmental impact.

How did we improve performance?

“The wastewater treatment process equipment by Owatec and Roxia Malibu automation have been innovative and the process is running smoothly. We have gained both savings and lower impurities levels.”

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 is a superb alternative to ozone, UV and chemical water 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.


Roxia Plasma Oxidizer is a superb alternative to ozone, UV and chemical water treatment.

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.

Project overview

  • No more odour problem caused by low oxygen level
  • Freezing problem eliminated
  • Remote monitoring saves operators’ working hours
  • Improved discharged water quality

Solution for bad odour

The customer had good previous experience with Roxia’s design and installation of a new smart automation system for the pumping station. Next, looking to reduce the odour and improve the state of the equalization basin, they again reached out to Roxia.

As a solution, Roxia recommended and later implemented a Smart Aeration System. It consists of five 1,5 kW Roxia Floating Aerators, located in the equalization basin. Since the commissioning of the Smart Aeration System, the odour problems have virtually disappeared. The basin stays ice-free through the winter. Adding oxygen to the equalization basin has also improved the discharged water quality.


Floating Aerators solve the odour problems caused by low oxygen level.

Automated cleaning cycles

Roxia Floating Aerators are integrated into the automation system. Their operation is automated based on ambient temperature measurement. The system also includes an automatic cleaning cycle where the impeller rotation direction is reversed periodically.

Through online access to live-view Via Roxia Malibu™ portal, plant staff can remotely access real-time information about aerators’ performance with any device with internet connection (e.g. smart phone, laptop). The online view replicates the real environment through a 3D model of the actual plant, which makes it easy for anyone to read the data without prior training. Monitoring of the operation and condition of the aerators is faster and easier than ever.
