Dovrat reservoir absorbs low quality secondary effluents, including pollutants and nutrients.
At the beginning of the spring and the rising temperatures, the growth of algae begins development of Daphnias and other microorganisms.
These algae, microorganisms and macro-organisms, which reach high concentrations, clog the filters and prevent irrigation.
Irrigation by the use of effluents is compromised and many components such as filters, drippers and other components become clogged and prevent regular irrigation.
Nano Bubble system installed for advanced oxidation to prevent repeated clogging,
The system oxidizes algae, daphnia and other microorganisms effectively achieving almost total clarity in the reservoir water.
Reservoir information:
• Reservoir water surface area – 7.1 Ha
• Reservoir water depth – up to 7 meters
• Maximum volume of the reservoir approx. 350,000 m3
Advantages of Nano Bubble as advanced oxidation method
• High efficiency and low energy investment.
• Testing of the effluent treated with this method indicates high efficiency of pollutant removal
• The concentration of oxygen in the reservoir treated with nano-bubbles increased and remained stable
• Removal of organic load in the water
Facility Description
• Floating nano bubbles ozone system
Results:
1. Testing the effluent at the reservoir outlet indicates a significant improvement in the quality of the effluent following activation of the nano-bubble system.
2. There is a significant visual improvement to the reservoir compared to the appearance of the reservoir prior to activation.
