A method for fluid treatment that provides variable or alternative regeneration cycles within the same fluid treatment device. The duration of all stages of the regeneration cycle can be adjusted depending upon the amount of fluid treated so that regenerant resources such as water are not underutilized and waste is not discharged unnecessarily into the environment.

1. A method for treating water, said method comprising: providing a water treatment device having a programmable controller configured to manage a first regeneration sequence followed by a second regeneration sequence, each of the first and second regeneration sequences comprising one or more correlative regeneration cycles, wherein the controller has been programmed with:a predetermined capacity of the treatment device,a predetermined time period for the second regeneration sequence to begin,a first predetermined duration for each regeneration cycle of the first regeneration sequence, anda trigger limit of at least one characteristic of the water treatment device to trigger a regeneration sequence;prior to an initiation of the second regeneration sequence, measuring a volume of water passed through the water treatment device since the completion of a prior regeneration sequence;initiating with the controller the first regeneration sequence;after the first regeneration sequence, programming the controller with a second predetermined duration for each correlative regeneration cycle of the second regeneration sequence, the second predetermined duration of each cycle of the second regeneration sequence being substantially equivalent to the first predetermined duration of the correlative regeneration cycle of the first regeneration sequence multiplied by the measured volume of water divided by the predetermined capacity of the treatment device;if at least one characteristic reaches the trigger limit prior to the second predetermined time period, initiating with the controller the second regeneration sequence of the water treatment device prior to the second predetermined time period utilizing the second predetermined duration for each correlative regeneration cycle; andif the second predetermined time period occurs prior to at least one characteristic achieving the trigger limit, initiating with the controller the second regeneration sequence of the water treatment device at the second predetermined time period utilizing the second predetermined duration for each correlative regeneration cycle. 2. The method of claim 1 wherein the first regeneration sequence has at least one cycle selected from the group consisting of: backwash, down brine, up brine, rinse, rapid rinse and brine tank fill. 3. The method of claim 1 wherein the at least one characteristic is selected from the group consisting of volume of water passed through the device, time the device has been in operation, ion depletion sensing within the device and pressure differential through the device. 4. The method of claim 1 wherein the second regeneration sequence occurs at a predetermined time. 5. The method of claim 1 wherein the second regeneration sequence occurs during a time period of minimal water use. 6. The method of claim 1 further including the step of, with the controller, automatically computing an average amount of water treated on a predetermined day, computing the remaining capacity of the device by subtracting the measured volume of water passed through the water treatment device since the completion of the first regeneration sequence, comparing the remaining capacity with the average amount of water treated on the predetermined day and initiating the second regeneration sequence if the amount of water treated on the predetermined day exceeds the remaining capacity. 7. The method of claim 1 further including the step of, after the second regeneration sequence, initiating with the controller the first regeneration sequence. 8. The method of claim 1, wherein the second regeneration sequence has more regeneration cycles than the first regeneration sequence. 9. The method of claim 1, wherein the second regeneration sequence has fewer regeneration cycles than the first regeneration sequence. 10. A method for treating water, the method comprising: providing a water treatment device having a programmable controller configured to manage regeneration sequences, wherein the controller has been programmed with:a first predetermined regeneration sequence including one or more regeneration cycles, each cycle having a predetermined duration,a capacity for the water treatment device,a time period for the first regeneration sequence, anda trigger point for at least one characteristic of the water treatment device;measuring the amount of water treated by the water treatment device;measuring at least one characteristic of the water treatment device;initiating with the controller the first predetermined regeneration sequence;after the first predetermined regeneration sequence is complete, computing with the controller the duration of each regeneration cycle of a second regeneration sequence to be substantially equal to the amount of water treated by the device divided by the device capacity, the quotient of which is multiplied by the predetermined duration of a corresponding regeneration cycle of the first regeneration sequence;if the trigger point occurs prior to the time period, regenerating the water treatment device utilizing the second regeneration sequence upon the occurrence of the trigger point; andif the time period occurs prior to the trigger point, regenerating the water treatment device utilizing the second regeneration sequence at said time period. 11. The method of claim 10 wherein first predetermined regeneration sequence has at least one cycle selected from the group consisting of: backwash, down brine, up brine, rinse, rapid rinse and brine tank fill. 12. The method of claim 10 wherein the characteristic is selected from the group consisting of volume of water passed through the device, time the device has been in operation, ion depletion sensing within the device and pressure differential through the device. 13. The method of claim 10 wherein the second regeneration sequence occurs at a predetermined time. 14. The method of claim 10 wherein the second regeneration sequence occurs during a time period of minimal water use. 15. The method of claim 10 further including the step of, with the controller, automatically computing an average amount of water treated on a predetermined day, computing the remaining capacity of the device by subtracting the measured volume of water passed through the water treatment device since the completion of the first regeneration sequence, comparing the remaining capacity with the average amount of water treated on the predetermined day and triggering the second regeneration sequence if the amount of water treated on the predetermined day exceeds the remaining capacity. 16. The method of claim 10 further including the step of, after the second regeneration sequence, initiating with the controller the first regeneration sequence. 17. The method of claim 10, wherein the second regeneration sequence has more regeneration cycles than the first regeneration sequence. 18. The method of claim 10, wherein the second regeneration sequence has fewer regeneration cycles than the first regeneration sequence. 19. A method of treating a water source, the method comprising the steps of: providing a water treatment device having a predetermined capacity, the device having a programmable controller configured to manage regeneration sequences, wherein the controller has been programmed with: a predetermined duration for each cycle of a first regeneration sequence, anda trigger to begin a second regeneration sequence upon the occurrence of a triggering event;measuring an amount of water treated by the device;initiating with the controller the first predetermined regeneration sequence;computing a duration of each regeneration cycle to equal substantially the amount of water treated by the device divided by the capacity of the device multiplied by the predetermined duration of the cycle;after the first predetermined regeneration sequence is complete, computing with the controller a duration of each regeneration cycle of the second regeneration sequence to be equal to the amount of water treated by the device divided by capacity of the device, the quotient of which is multiplied by the predetermined duration of a corresponding regeneration cycle of the first regeneration sequence; andregenerating said water treatment device utilizing the second regeneration sequence after the occurrence of the triggering event. 20. The method of claim 19 wherein the first regeneration sequence has at least one cycle selected from the group consisting of: backwash, down brine, up brine, rinse, rapid rinse and brine tank fill. 21.
