Abstract

Abstract A fluid treater has multiple flow paths in order to treat large quantities of water, for example, with an electric field without substantial pressure drop. The treater is provided with a lower intake manifold having a configuration which causes essentially laminar flow of the water in the manifold along a spiral path having convolutions of successively reduced diameter. Outlet ports of the manifold are spaced along such path and are in communication with tubular, outer electrodes through which the water is swirled upwardly by helical guide screws to a similarly arranged upper discharge manifold where the plural paths are recombined. Through the use of a set of inner electrodes coaxially disposed within the outer electrodes, the water in each path is subjected to a radial electric field in the annular passage defined by the respective inner and outer electrode pair. The tubular wall of each outer electrode is inset to concentrate the electrostatic field in the annular passage, the inner electrode having an electrically conductive outer surface at least coextensive with the tubular wall. The construction permits any of the inner electrodes to be readily replaced without disassembling the treater.
