OwaAir - aeration and biochemical treatment unit
OwaAIR is a solution built in a sea container, which is available in two different sizes: a six or 12-meter container. In addition to a large air supply, water treatment can be enhanced with various biological methods, which can potentially reduce the need for chemicals.
The efficiency of the aeration unit is based on a large amount of air supplied from the bottom of the pool and biological treatment. The flow capacity can be up to 20 m3/h, and this pretreatment significantly affects the reduction of pollutants such as BOD and COD.
Examples by industries:
- Pulp and Paper Industry – wastewaters and fiber recovery
- Food Industry – wastewater
- Waste Management – run-off and reject water
