Abstract
An ion exchange liquid treatment apparatus including a tank having an upwardly dished bottom wall and a distributor of the type having a central header and a plurality of distributor conduits extending outwardly from this header. Each distributor conduit is formed of a first straight conduit section that extends generally radially outwardly from the header and a second straight conduit section that is connected to the first conduit section by a pipe elbow whereby the second conduit section can be positioned oblique to a plane through the longitudinal axis of the tank and at a shallow angle to a plane perpendicular to the tank axis to generally conform to the contour of the dished bottom wall of the tank. Each of the second distributor conduit sections preferably have lateral conduits extending transverse thereto to achieve generally uniform liquid flow throughout the cross-section of the tank. The distributor conduits are supported on the tank bottom by a distributor support structure including radially extending arms and annular ring members interconnected to form a generally frusto-conical grid that underlies and supports the distributor conduits.
