Research Area: Desalination

Our Objective

WRF research on desalination is conducted to determine the effectiveness, practicality, and benefits of desalination in today’s world. 

The main goals of WRF's desalination program are to further the knowledge and understanding of desalination in regards to treatment strategies, regulatory concerns, cost implications, concentrate management, and environmental effects and provide effective tools and information regarding the benefits of desalination as part of a diverse water portfolio.

Case Study of the City of Carlsbad and Surrounding Areas’ Experience with Integrating Desalinated Seawater Supply in Municipal Distribution Systems (Ongoing)
This project will provide independent review of the impacts from introducing desalinated seawater into an existing distribution system, including but not limited to quantifying source water quality changes, water quality effects (e.g. corrosion, disinfectant residual, etc.), and public acceptance.
Performance and Cost Review of Existing Desalination Plants which use Conventional and Membrane Pretreatment Processes Prior to RO (Ongoing)
This project will provide utilities with information on key criteria that can assist during the planning phase for membrane desalination plants, related to the evaluation of different pre-treatment processes and provide a process selection decision matrix which optimizes capital and operating costs against performance and regulatory requirements.
