Purpose and Background
The primary objective of the water treatment plant design process is to meet target water quality requirements, optimize treatment process efficiency and minimize initial investment and long-term operating costs. Meeting these objectives reliably can be facilitated by integrating powerful predictive modeling and simulation tools in the design process to accurately predict the multiple interactions between all the water quality and process design parameters and support the design optimization process. Commercially available Computational Fluid Dynamics (CFD) modeling tools, coupled with recent advances in computing resources, allow for the modeling and optimization of water treatment plant systems that previously would have been optimized based on engineering judgement/experience and/or physical model studies. Two-phase, reactive, transient simulations coupling multiple water treatment system components are now possible in time frames that support the demanding schedules of water treatment plant design programs. This webinar discusses CFD integration in water treatment plant design.
