Abstract: The paper presents the results of theoretical and experimental research performed on two liquids: 1) drinking water from the Bucharest water-supply network; 2) water from Lake Plumbuita, peripheral to Bucharest city. A fine bubble generator (FBG) constructive solution is exposed; using a micro-drilling machine, Ø 0.5 mm orifices were made in the perforated plate of FBG. The experimental installation, designed in an original manner allows precise measurement of the increase in dissolved oxygen concentration in the water basin in function of time. The variation of the dissolved oxygen concentration in water, depending on the oxygenation process time, which occurs in non-steady state, is revealed

Keywords: fine bubble generator dissolved oxygen, water oxygenation
