Rezumat: Scopul lucrarii este de a prezenta un tip de generator de bule fine care reduce timpul de oxigenare a apelor de doua ori. Initial, intr-un rezervor cu apa se introduce un generator de bule fine, imobil, avand 37 de orificii cu Ø0,5mm: Se mentin constante debitul de aer introdus in apa si sarcina hidrostatica; concentratia la saturatie a O2 dizolvat in apa se atinge in doua ore. Ulterior, in aceleasi conditii, se incearca generatorul de bule fine care are placa cu orificii antrenata in miscare de rotatie si se constata reducerea cu o ora a timpului de oxigenare a apei.

Cuvinte cheie: generator de bule fine, oxigenarea apei


Abstract: The purpose of this paper is to introduce a type of fine bubble generator that reduces two times the water oxygenation time. Originally, a fixed fine bubble generator, fixed, having 37 nozzles of Ø0.5mm, is introduced in a water tank: the air flow introduced into water and the hydrostatic load are maintained constant; the saturation concentration of the O2 dissolved in water is reached in two hours. Consequently, in the same conditions, a fine bubble generator that has the nozzle plate involved in a rotational motion is tested. It is remarked that the water oxygenation time is reduced by one hour.

Keywords: fine bubble generator, water oxygenation
