Enhancing Ecological Design Principles in Vortex Settling Basins for Sustainable Water Management

Year: 2025

Type: article

Abstract: Continuous flushing systems such as vortex settling basins (VSBs) are commonly utilized to remove sediment particles in power plants and irrigation and drainage networks. This study evaluates the performance of a typical VSB, focusing on sediment removal efficiency (ηe), flow efficiency (ηflow), and inlet canal efficiency (ηin). In the continuous operation of VSBs, sediment removal efficiency remains the appropriate metric, as opposed to trapping efficiency. The impact of hydraulic and geometric parameters was analyzed using the Taguchi design, experimental modeling, and statistical analysis through response surface methodology (RSM). The performance of the VSB was evaluated using the ANOVA test, along with the Pareto chart and the desirability function approach for multi-objective optimization. The predicted optimal values for ηin, ηe, and ηflow were 94.09%, 69.40%, and 91.67%, respectively. This optimum condition for having higher efficiency in the VSB was for the case with 0.3625 mm particle diameter, 0.1 m orifice diameter, 0.1 m end sill height, 22 L/s inlet discharge, and 0.05 m outlet weir. Larger sediment particle size and inlet discharge enhanced VSB desirability, while smaller orifice size and outlet weir height are preferred for optimal performance. This paper provides a framework for the optimum design of VSBs.
