Do you have design recommendations for highly variable flows?
The Fuji Clean system is designed to accommodate variable flows via the recirculation airlift pump, which has a built in mechanism for leveling variable flow to maximize retention time and treatment. Research shows that the average effluent flow rate for Fuji Clean residential systems is 0,82-gpm. (Please contact Fuji Clean for details). For extreme variable flows (such as in a church situation where there is a very large peak flow one day a week), we recommend the installation of a preceding settling tank large enough to accommodate total peak flow and metered or dosed flow to the system throughout the unused periods.
