Pool filtration has remained largely unchanged for the past 50+ years. This presentation will discuss how to apply the latest filtration science and research findings to the pool to improve water quality and clarity. Whether attendees are interested in the operations & maintenance of existing filters or the design of new filter systems, this presentation will provide targeted insights into making improvements, now. New methods of calculating filter performance impacts on pool water quality will be demonstrated to allow users to intelligently decide the best way to achieve water quality goals. New filtration technology will be presented as well as the needs for future research and regulatory changes.
