Reasearches Regarding the Measurements of the Dissolved Concentration in Water

-The paper presents how advanced technologies can serve to solve some water aeration plants problems. The construction of fine air bubbles generators is needed for an efficient water aeration. The main element of those generators is the orifice plate for air injection in the water mass. The research team has built a fine bubble generator with 152 orifice plate (Ø 100 μm) which can be achieved through spark-erosion or microvoids technologies. The theoretical and experimental researches on increasing the dissolved oxygen concentration in water have led to satisfactory results.

Researches on Aeration of Stagnant Water or Flowing Through Pipes

2019

The paper presents two experimental installations that will be used to measure the dissolved oxygen concentration in wastewater. The first installation refers to stagnant wastewater and the second to wastewater flowing through pipes. The sketches of the two installations, the fluids circulation and the measuring devices are presented. The results of the theoretical and experimental researches regarding the increase of the dissolved oxygen content in water in the case of the two experimental installations will be presented in a subsequent paper.

“…The fine bubble generator (FBG) is fed by its two ends, namely through the 16 and 17 pipes ( Figure 7). Regarding the experimental installation it is stated [15,16]:…”

Researches on the Measurement of the Dissolved Oxygen Concentration in Stationary Waters

2018

The paper presents methods for measuring the dissolved oxygen concentration in water; the electrical method is presented by presenting an experimental installation designed and built in the laboratories of POLITEHNICA University in Bucharest. For the creation of fine air bubbles, a bubble generator with 0.1 mm orifices processed by spark-erosion was used. The results of the experimental researches on the measurement of dissolved oxygen in water are presented.
