Rezumat: In lucrare se prezinta influenta cresterii concentratiei de oxigen dizolvat in apa asupra randamentului procesului de oxigenare a apei. Se integreaza numeric ecuatia diferentiala a vitezei de transfer a oxigenului dizolvat in apa cu metoda Euler; se elaboreaza un program de calcul pentru stabilirea cresterii concentratiei de oxigen dizovat in apa in functie de timp. Rezultatele obtinute din calcul sunt comparate cu valorile marimilor masurate experimental.

Cuvinte cheie: oxigen dizolvat in apa, viteza de transfer a oxigenului

Abstract: The paper presents the influence of the increase of the dissolved oxygen concentration on the efficiency of the water oxygenation process. The differential equation of the transfer speed of the dissolved oxygen is numerically integrated using the Euler method; a software application is written in order to establish the manner in which the dissolved oxygen concentration increases in function of the time. The computed results are compared with the values of the experimentally measured values.

Keywords: dissolved oxygen, oxygen meter
