The effect of backwashing rate on filter performance
In a series of plant‐scale investigations, two identical filters were subjected to fluidization and subfluidization backwashing rates. A higher initial degradation of the effluent turbidity was observed for filters in which subfluidization conditions prevailed. The head loss was higher for filters back washed at a lower rate resulting in shorter filter runs. The study confirmed the existence of two peaks during the degradation of filter effluent quality during the initial part of the filter run. Mudball formations did not occur during backwashing at subfluidization velocities. Lower backwashing rates have economic advantages.
