Research Description

Dr. Ducoste is interested in the operation, design, and optimization of drinking water and wastewater treatment processes. He achieves these goals by incorporating novel experimental techniques and validated numerical models in the analysis of unit processes. He has research experience in the operation and design of chemical mixing, flocculation, sedimentation, and chemical and UV disinfection processes in drinking water treatment. Dr. Ducoste is an expert in modeling water and wastewater treatment process fluid mechanics using Computational Fluid Dynamics (CFD). He has developed CFD models for analysis of chemical and UV disinfection reactors, rapid mix chambers, flocculation basins, filtration systems, wastewater activated sludge systems, waste stabilization ponds, secondary clarifiers, and food waste systems. Dr Ducoste is also interested in modeling cellular regulatory and metabolic pathways and interfacing product formation to produce bioreactor models using CFD.
