A decomposition tube for an exhaust treatment system includes a housing with a housing wall that defines an exhaust flow path for exhaust; a reductant delivery mechanism coupled to the housing and having a nozzle configured to deliver a spray of reductant into the exhaust flow path; and a mesh device with a mounting element mounted on the housing wall and a mesh basket secured to the mounting element proximate to the nozzle to enclose and intercept the spray such that effectively all of the reductant passes through the mesh basket and into the exhaust flow path prior to impinging on the housing wall.

An SCR system comprising a reductant tank, a return passageway, and a reductant distributor. The return passageway is coupled fluidly to the reductant tank via an outlet of the return passageway. A reductant distributor is positioned at the outlet. The reductant distributor is configured to distribute spatially an undispensed portion of a reductant into the reductant tank from the return passageway.
