Abstract: For efficient water aeration, it is necessary to construct fine air bubble generators in which the main element is the plate with orifices for the introduction of air into the water. The research team constructed a fine bubble generator having 152 orifices with Ø 0.1 mm, which can be obtained by spark-erosion or micro-drilling. An experimental plant has been designed and built to see how the generator operates and the pressure loss that occurs when the air passes through it. The theoretical and experimental research on increasing the dissolved oxygen concentration in water led to satisfactory results.

Keywords: water aeration, fine air bubble generators.
