Abstract. The paper presents two types of fine bubble generators with the same number of nozzles, but differently placed. These two types of generators will be used in order to experimentally research the efficiency of the water oxygenation process; an experimental setup was designed and built; the setup is endowed with modern instruments: oxygen meter, manometer, thermometer, all of them having digital display. The results of the experimental measurements will indicate the most favorable generator architecture from the point of view of the increase of concentration of oxygen dissolved in water. Keywords: oxygen meter, fine bubble generator, oxygen dissolved in water Rezumat. În lucrare se prezintă două tipuri de generatoare de bule fine care au acelaşi număr de orificii dar amplasate în mod diferit. Cu ajutorul acestora se va cerceta experimental eficienţa procesului de oxigenare a apei; s-a conceput şi construit un ştand experimental prevăzut cu aparate moderne: oxigenometru, manometru, termometru, toate cu afişare digitală. Rezultatele măsurărilor experimentale vor indica care dintre cele două generatoare are o arhitectură mai favorabilă, privind creşterea concentraţiei de oxigen dizolvat în apă. Cuvinte cheie: oxigenometru, generator de bule fine, oxigen dizolvat în apă.
1. INTRODUCTION Oxygenation, named in also aeration in specialty literature [1] [2], constitutes the main operation that assures a proper quality of water in water treatment and purification processes. Water oxygenation is a process of mass transfer (O2 → H2O) largely applied in the following areas: – water treatment processes; – biological purification of wastewater; – separation and catchment of greases from wastewater.
