Abstract
A fluid treatment device is described which includes a cylindrical housing with fluid inlet and outlet means at or adjacent opposite ends. Particulate material for treating fluid flowed through the device, is disposed within the housing, between the inlet and outlet means. A helical baffle is disposed within the housing in the particulate material. The baffle extends axially along the housing and the free edges of its fins are in contact with the housing. The baffle serves to impose a helical path on fluid flowing through the device so that, when the device is mounted with its axis horizontal and with a volume of particulate material less than the volume of the space within the housing, fluid flows through the particulate material most of the time and not entirely along the void as would be the case if the baffle were not present.
