Increasing demand on available water supplies has led many utilities to consider potable reuse. Typical projects rely on treatment processes such as microfiltration/ultrafiltration, reverse osmosis (RO), and ultraviolet disinfection, with advanced oxidation processes. These proven approaches produce high quality drinking water; however, the treatment processes are capital and energy intensive, particularly for inland facilities where disposal of RO brine can be cost-prohibitive.
This webcast focuses on a research project evaluating an alternative treatment train using two-stage ozone-biofiltration – without reverse osmosis – to achieve potable quality water. The presentation will include the research drivers and background, outline the pilot study objectives, and provide a summary of results from the drinking water pilot as well as the upstream advanced treatment facility. A cost comparison will be presented showing significant capital and operating cost savings of this non-RO based treatment approach.
This research provides valuable information to the water industry by demonstrating the strengths and challenges associated with this non-RO approach to potable reuse.
