Apparatus for treating fluids

A fluid treatment system for contacting a fluid with contact media, comprising:

• a treatment vessel having a plurality of vertically aligned chambers, said chambers defined by apertured members adapted to retain a contact media within the chamber, each chamber for holding a slug of said contact media;
• a fluid inlet for untreated fluid to direct said untreated fluid proximate the top of the uppermost chamber of said plurality of chambers;
• a first media treatment tank for periodically treating slugs of said contact media;
• a first manifold;
• a first plurality of conduits, said conduits distributed to direct fluid between said first manifold and one of said chambers;
• a second manifold;
• a second plurality of conduits, said conduits distributed to direct fluid between said second manifold and one of said chambers;
• a third plurality of conduits distributed to direct fluid between said second manifold and said first media treatment tank;
• a first pump having its output communicatively coupled to said first manifold;
• a first valve coupled to said media treatment tank and to the input of said first pump, for controlling the flow of fluid out of said media treatment tank;
• a second valve coupled to said media treatment tank;
• and
• a second pump having an output coupled to said second valve, for controlling the flow of fluid into said media treatment tank.
