| Descripción : | Within a wastewater treatment plant (WWTP), the aeration process promotes the biological oxidation carried out by aerobic microorganisms, degrading the soluble and suspended organic matter. This process can be observed in facultative lagoons and especially in activated sludge processes. The aeration is carried out by means of air diffusers at the bottom of the aeration tank, stimulating the agitation and mixing of the fluid. The aim of this study is to build a model of air diffuser for waste water treatment. Starting with design, construction and evaluation of an air diffuser. For the design, two dome type diffusers were proposed, with acrylic plates with different hole diameters (2 and 4 mm) and fine bubble diameter (2 mm). Then the diffuser was printed in 3D. During the evaluation, DIN EN 12555-15 2003 was used to determine the coefficient or oxygen transfer rate in the aeration tank. In the experimental design, a null was established (hose without diffuser). The diffusers and the hose were evaluated at three water heights (0.8, 1.6 and 2.4 m). Having an experimental design with 9 treatments (27 experimental units). Statistically there was no significant difference between the oxygen transfer rate data. However, plate 2 showed maximum differences of time in reaching a concentration of 8 mg / l, unlike the hose. Environmental conditions were determined, such as: the concentration of sodium sulfite, the dilution time and the water saturation time. It was confirmed from Shapiro-Wilks that the data on the oxygen transfer rate have a uniform distribution. It could be concluded that, the longer water depth, the higher rate of oxygen transfer because of the residence bubble time. |
