What is media retention screen

Media retention screens are designed to retain AquaCELLTM biofilm carriers in the appropriate reactor basin and allow for the passage of effluent and suspended solids to the next stage of the treatment process. Media screens are cylindrical or flat plate and are provided as flange mounted units or housed in an effluent tee for easy removal.

As biofilm carriers move throughout the water column in an aerated or mixed basin they regularly contact the media retention screen(s) and scour the surface to prevent biomass accumulation in the screen orifices. Thus the screens do not typically require manual cleaning.
