🫧 AWWA Backwash (Air 3 SCFM/Sq Ft + Water 5 GPM/Sq Ft, Collapse Pulsing Dynamics)

Concurrent Air-Water Backwash & Collapse Pulsing Calculator

Model concurrent air-water backwash hydraulics creating vigorous "collapse pulsing" abrasion: combine sub-fluidization water upflow (5 to 8 GPM/Sq Ft) simultaneously with low-pressure air scour (3 to 5 SCFM/Sq Ft) to shear adhesive mudballs and coagulant flocs from sand grains (saving 40% backwash water volume), and plant efficiency yields.
