Abstract

Embodiments of a water treatment system, a method of regenerating a water treatment system, a use of a water softener valve and an ozone kit for a water filtration system are provided. The water treatment system includes a water tank containing iron filtration media; an ozone gas source having an outlet; and a water softener valve having a venturi nozzle that is associated with the water tank and in fluid communication with the outlet of the ozone gas source, the water softener valve configured to invoke a regeneration mode during which the water softener valve controls backwashing of the iron filtration media and then permits ozone gas from the ozone gas source to be drawn through the venturi nozzle and into the water tank.

Claims

1. A water treatment system comprising:

a water tank containing iron filtration media;

an electronic control valve associated with the water tank and including;

a venturi nozzle in fluid communication with the upper interior of the water tank; and

a control system having a control board programmed to enter and exit service and regeneration modes of the electronic control valve to control passage of water through the electronic control valve to and from the water tank;

the water treatment system further comprising;

an ozone gas generator electrically connected to a relay switch receiving electrical signalling from the control board and in response controlling access to electrical power by the ozone gas generator to start and stop generating ozone gas, the ozone gas generator conveying generated ozone gas out of an ozone gas outlet;

a gas conduit associated with the ozone gas outlet and the venturi nozzle to convey the generated ozone gas by vacuum into the upper interior of the water tank via the venturi nozzle; and

a check valve associated with the conduit to normally block flow through the conduit, the check valve openable only during the regeneration mode upon application of vacuum through the conduit from the water tank.

2. The system of claim 1, wherein the water tank contains additional media capable of further filtering out of the water at least one of:

manganese and sulphur.
