정수장 관내 직조 금속 여과망의 손실 특성에 관한 연구

초록

This study aims to analyze the flow characteristics of filter mesh assemblies used in advanced water treatment plants. In these facilities, filter meshes are essential for removing suspended solids and organic matter that are not filtered out during sedimentation. Various installation methods and types of metal screens exist; however, pressure losses from the design and operation of these meshes significantly impact water treatment efficiency. Existing research primarily focuses on pressure drop equations and modifications to friction factors for porous media, but variability in testing conditions and flow characteristics limits their applicability. This study utilizes Computational Fluid Dynamics (CFD) to simulate the flow through filter mesh assemblies and conducts experimental validation using empirical velocity profiles within the conduits. It is through this research that pressure drop models based on filter mesh assemblies and porosity are proposed, providing foundational data for optimized design in water treatment facilities.
