An apparatus for reducing the concentration of a constituent in a fluid. A portion or all of the constituent is removed from a portion of the fluid and the constituent free portion is remixed with constituent containing portion. In a flowing system, a limited range electrolytic titrator may analyze the mixed output when the input concentration varies over a very large range. The apparatus of the invention may include a three way valve to pass the input thereto either through a filter or through a bypass. The three way valve may be a solenoid valve operated by a pulse generator. A needle valve may be employed in the bypass, but need not be employed at all in many cases. If a single conduit from where the filter and bypass outputs join is not fairly large or long, preferably a mixing tank or other mixing device is provided. |
