Method of treating water with an ion exchange bed in a water treatment system

A method of treating water with an ion exchange bed in a water treatment system, the method comprising:

• introducing water to be treated into the ion exchange bed of the water treatment system to produce treated water;
• calculating a current exchange daily average flow rate of water through the water treatment system for a current period of time;
• calculating a cumulative daily average flow rate of water through the water treatment system including calculating the exchange daily average flow rate of water for a plurality of periods time between a plurality of instances of replacing the ion exchange bed;
• determining an estimated number of days remaining to exhaustion of the ion exchange bed during the current period of time based on the current exchange daily average flow rate and the cumulative daily average flow rate;
• generating a request for replacement of the ion exchange bed based on the estimated number of days remaining;
• and
• transmitting the generated request for replacement of the ion exchange bed to a central server.
