Optiva Contributes to New, Energy-Efficient Treatment Technology at ØyVAR

New Requirements – New Technology

To meet stricter treatment requirements and population growth, many municipalities must upgrade their wastewater treatment plants. To identify the right solution, ØyVAR has tested biological treatment using CFIC technology (Continuous Flow Intermittent Cleaning), developed by the Norwegian company Biowater Technology.

Optiva has been a key partner in the development and testing of this technology. The goal of the project is to reduce energy consumption, operating costs, and environmental impact while maintaining or improving treatment efficiency. Through close collaboration and hands‑on support, Optiva has helped prepare innovative solutions for full‑scale operation. The results will form the basis for comparing different solutions and selecting the process for the upgraded facility.

Project Support From Idea to Pilot Facility

Optiva has followed the project from the early concept phase to practical field testing. This includes support in planning the test setup, collecting operational data, and evaluating results. Experiences from the pilot plant provide valuable insight into how the technology performs under real conditions and form the basis for further improvement and development.

In cooperation with ØyVAR, emphasis has been placed on documenting effects on energy use, treatment performance, and operational stability. This documentation is essential for making well‑informed decisions about future investments and large‑scale implementation.

Through analyses and continuous adjustments, Optiva has helped fine‑tune the interaction between mechanical, biological, and chemical treatment. The aim has been to ensure stable operation, high treatment efficiency, and low energy consumption, while keeping the system easy for operators to manage.
