10. A method of filtering influent, comprising:
providing an influent flow to a set of modules stacked on top of each other, each module including screen assemblies and filter
media sandwiched between the screen assemblies;
filtering the influent by directing the influent through fluid lines and control assemblies operable for selectively communicating
flow to individual modules;
selectively bypassing a forward flow from a module being bypassed around a subsequent module when the module becomes occluded,
the forward flow being reintroduced from a previous module to a subsequent module; and
backwashing the occluded module by providing a reverse flow through the screen assemblies and the filter media while bypassing
the forward flow around the occluded module.
