There are many types of SBR systems, including
continuous influent/time based, non-continuous
influent/time based, volume based, an intermittent
cycle system (a SBR that utilizes jet aeration), and
various other system modifications based on
different manufacturer designs. The type of SBR
system used depends on site and wastewater
characteristics as well as the needs of the area or
community installing the unit. Package SBRs are
typically manufactured to treat wastewater flow
rates between 0.01 and 0.2 MGD; although flow
rates can vary based on the system and
manufacturer.
