Benefits of Air-Assisted Backwash of Granular Filter Media - A Slide ShowTom & Tim.JPG

 

This presentation summarizes comparative operational performance data stemming from a water treatment plant filter upgrade completed in 2009. It illustrates the installation of air-assisted backwash (air scour) and details the resulting changes in backwash protocols. The paper also quantifies the economic benefits of the upgrade in terms of reduced backwash water use and reduced frequency of filter backwashing. A series of slides illustrate the revised backwash process.
