Abstract: An aftertreatment system for treating a high-volume exhaust flow is provided. The aftertreatment system includes a filter module. The aftertreatment system also includes a conduit in fluid communication with the filter module. The aftertreatment system further includes at least one aftertreatment module in fluid communication with the conduit. The filter module is adapted to selectively receive at least one filter element therein. The at least one filter element is adapted to reduce a backpressure within the aftertreatment system. The filter module is also adapted to provide incremental levels of particulate matter reduction from the exhaust flow based, at least in part, on a number of filter elements therein.
