1. A method for providing treated water on a continuous basis with a variable water demand employing a progressive flow water treatment system having a first treatment tank and a second treatment tank, and having a controller programmable by input from an operator, the method comprising the steps of:

  • receiving an input designating a progressive flow program type;

    receiving an input for a total volume for a regeneration parameter;

    receiving an input for a flow rate trip level value;

    directing water flow to provide treated water through the first treatment tank;

    monitoring the flow rate of water through the first treatment tank;

    comparing the flow rate to the received flow rate trip level value;

    additionally directing water flow through the second treatment tank if the flow rate exceeds the flow rate trip level value;

    monitoring the total volume through each treatment tank; and

    ,initiating a regeneration of each treatment tank when total volume exceeds the input total volume regeneration parameter.
