A filtering system (10) includes a set of modules (40,60,80) which each include filter media (44,64,84) sandwiched between screen assembles (43,63,83). Control assemblies (50) are associated with each module, which each selectively controls flow between a forward flow, a bypass flow and a reverse backwashing flow. The system is used in a filtering method that includes providing an influent flow to the modules and selectively bypassing and providing reverse backwashing flow to the modules when they become occluded.
