SOFTWARE DEVELOPMENT FOR HYDRODYNAMIC STUDY IN WATER AND WASTEWATER TREATMENT SYSTEMS

Abstract

This paper presents software developed for treatment data from an Acoustic Doppler Velocimeter (ADV) probe applied to hydrodynamics studies. The software developed here was tested using a dissolved air flotation (DAF) pilot plant in water and wastewater treatment applications. The ADV principle is largely used in velocimeters, but the data are commonly presented in timetabled results. Thus, the software intended to statistically treat tabled data, to plot the vectors and to produce more comprehensive surface (3D) graphs for vector visualization. It is also possible to take detailed cross-section cuts in any portion of the vector grid, thereby creating a 2D visualization of the velocity intensity. This software should prove useful as a tool for treatment improvement, and it should contribute in the reactors hydrodynamic analyses.
