Abstract: An aftertreatment system for treating a high-volume exhaust flow is provided. The aftertreatment system includes a first module having a first mixing element, and a second module having a second mixing element. The aftertreatment system also includes a main inlet conduit, a first inlet conduit, a second inlet conduit, a first outlet conduit, and a second outlet conduit. Each of the first inlet conduit and the second inlet conduit is adapted to split the exhaust flow downstream of the main inlet conduit into a first stream and a second stream flowing therethrough respectively. The splitting of the exhaust flow is adapted to limit a backpressure within the aftertreatment system. Each of the first mixing element and the second mixing element is adapted to improve a mixing of the first stream and the second stream within the first module and the second module respectively.
