Abstract

Deficit of air in water causes complications with cyanobacteria mainly in the summer months. Cyanobacteria is a bacteria that produces poison called cyanotoxin. When the concentration of cyanobacteria increases, the phenomena „algal bloom“ appears, which is very toxic and may kill all the organisms. This article describes new equipment for aeration of water in dams, ponds and reservoirs with small depth. This equipment is mobile and it is able to work without any human factor because its control is provided by a GPS module. The main part of this equipment consists of a floating pump which pumps water from the surface. Another important part of this equipment is an aerator where water and air are blended. Final aeration process runs in the nozzles which provide movement of all this equipment and aeration of the water. Simulations of the flow are solved by multiphase flow with diffusion in open source program called OpenFOAM. Results will be verified by an experiment.
Článek popisuje nové aerační zařízení pro nádrže, přehrady a rybníky s malou hloubkou hladiny. Vynalezené zařízení může být použito pouze pro destratifikaci nebo pro destratifikaci kombinovanou s aerací. Tento článek je obsahuje konstrukční řešení aeračního zařízení, simulaci ve open source programu OpenFOAM a experimentální ověření.
