Water treatment system and method

A method of producing treated water comprising introducing a portion of water to be treated from a point of entry into a first zone of a vessel;

• introducing a portion of the water from the vessel into the electrodeionization device;
• applying an electrical current below through the electrodeionization device to promote removal of any undesirable species from the water and produce treated water;
• and
• introducing at least a portion of the treated water from the electrodeionization device into a second zone of the vessel, the second zone separated from the first zone by at least one baffle;
• and
• controlling at least one operating parameter of the electrodeionization device depending upon volume of water in the treated, second water zone and volume of water in the untreated, first water zone of the vessel.

A water treatment system comprising:

• a water storage vessel fluidly connected to a point of entry, the water storage vessel comprising a plurality of zones having water contained therein with differing water quality levels;
• an electrochemical device fluidly connected to the point of entry and the water storage vessel, the water storage vessel containing at least one baffle and fluidly coupled to the electrochemical device so as to define at least two of the zones of differing water quality levels such that at least one zone contains water which has been treated by the electrochemical device and at least one zone contains water which has not been treated by the electrochemical device;
• a power supply for providing an electrical current to the electrochemical device;
• and
• a controller system for regulating the electrical current below a limiting current density and operable for controlling at least one operating parameter of the electrodeionization device depending upon volume of water in a treated water zone and volume of water in an untreated water zone of the vessel.
