Fluid treatment tank having a laser welded distributor plate
A distributor plate for a fluid treatment tank such as a water softener pressure vessel separates the resin bed from a lower end of the resin tank. The outer peripheral surface of the distributor plate is laser-welded to an inner peripheral surface of the tank. The outer peripheral surface of the distributor plate may have a biasing mechanism that biases the outer peripheral surface of the distributor plate against the inner peripheral surface of the tank. The biasing mechanism may include a plurality of peripherally-spaced resilient fingers extending axially and radially away from a circular base of an outer ring of the distributor plate into engagement with the inner peripheral surface of the tank liner, each of the fingers having a base connected to the base of the ring and having a free end. Also disclosed is a method of making a fluid treatment tank.
A water treatment system has a water treatment tank that stores a resin bed, a conductivity monitor, a valve assembly, a flow meter, and a controller. The control valve assembly is switchable to selectively permit untreated water flow into the tank, treated water flow out of the tank, and regenerant flow into and out of the tank. In one configuration, the conductivity monitor includes at least an uppermost probe located within 6" of the nominal mid-point of the resin bed and a second probe located half-way between the first probe and the bottom of the resin bed. Signals from these probes are used in combination with flow data as measured by the flow meter to provide precise information regarding volumetric capacity as depletion is registered at each probe. Also disclosed are an improved technique for sampling data from the conductivity monitor, and a wireless conductivity monitor.

A fluid treatment tank for an aeration filter has an air blocker separating a chamber in fluid communication with a control valve of the filter from a pocket of air above the liquid in the tank and the control valve. The air blocker contains a volume of liquid that acts as a trap that prevents or at least inhibits air in the pocket from backing up into the chamber. Contact between the control valve and air is dramatically reduced. The air blocker may comprise a baffle that directs any air flowing through the air blocker downwardly and then back upwardly before the air can escape the air blocker.

Distributor arrangement for a fluid treatment tank
A distributor plate for a resin tank of a fluid treatment device such as a water softener includes a central hub, an outer ring, a plurality of ribs extending between the hub and the ring and dividing the distributor plate into discrete segments, and a slotted plate connected therebetween. The distributor plate separates the resin bed from a lower end of the resin tank. The distributor plate further comprises at least one valve plate coupled to an underside of the distributor plate over at least one segment thereof. The valve plate is constructed from a material configured to float in the fluid being treated and is movable between a raised position during upflow and a lowered position during downflow. In this manner, the valve plate acts like a check valve to regulate the manner in which fluid flows through the distributor plate during upflow and downflow, improving resin scrubbing during upflow.
A fluid treatment device includes a tank containing a fluid treatment medium and a fluid. A distributor plate is received in the tank and separates the bed from a lower end portion of the tank. A baffle is positioned beneath the distributor plate and is configured to direct fluid exiting a riser tube of the fluid treatment device toward the peripheral of the tank to thereby provide a more evenly-distributed flow through the radius of the distributor plate and through the fluid treatment medium. The baffle may have a downwardly facing concave surface that traps air bubbles generated during a brine draw operation.
A valve assembly for a twin tank-type water treatment system includes and a tank selector valve assembly that includes first and second rotary selector valves driven in concert with another by a reversible electric motor. The motor drives the first and second selector valves between (a) a first position in which an untreated water inlet and a treated water outlet of the valve assembly are coupled to a first resin tank, and a second resin tank is connected to a regeneration valve, and (b) a second position which the untreated water inlet and the treated water outlet of the valve assembly are coupled to the second resin tank, and the first resin tank is connected to a regeneration valve. The rotary valves may be disks that rotate relatively rapidly on a common shaft driven by the electric motor through an arc of 180.degree. or less.
