OwaDAF - Flotation unit
OwaDAF is a solution built in a sea container, available in two different sizes: 20 and 40 feet containers. With efficient multiphase technology, the separation of solids can reach up to 98% of the result, which enables water treatment according to the circular economy in various industrial sectors.
The efficiency of the flotation unit is based on the KTM Bubble Generator – multiphase pump, which feeds micro and nanobubbles that separate solid matter and other impurities to the surface, making traditional dispersion or pure water supply unnecessary. In addition to air, the KTM Bubble Generator pump can feed other gases into the water, such as nitrogen and oxygen.
The flow capacity of one unit is approx. 50 – 300 m3/h, which can be increased with a set of several flotation units. The quality of the treated water always determines the final maximum capacity flow.
Examples by industries:
- Food and beverage industry – wastewaters
- Waste management – runoff and reject waters

Benefits
Cost-effective
Owatec water treatment plant can enable savings of up to 25% per year.
Better water quality
The treatment can achieve up to 98% separation of solids and efficient separation of other impurities, which enables stream return to processes or other uses.
Realibity
Effective technology in modular container solutions.
Effective solid removal
Micro- and nano-bubbles supplied by the KTM Bubble Generator – multiphase pump separate solid matter and other impurities on the surface, making the traditional supply of dispersion or pure water unnecessary. In addition to air, the pump can also feed other gases into the water, such as nitrogen and oxygen.
Remote control
Automation, as well as remote connection and monitoring, enable continuous maintenance of optimized processes.
Modularity
Just Plug and Play -water treatment and sludge drying solutions in containers. The units are assembled at Tupos in Oulu and are ready for an operation soon after delivery.
