A method for predicting end-of-life of a system consumable in a fluid purification system characterized by the steps of (a) coupling a model consumable to the fluid purification system which has comparable characteristics but substantially less time capacity than the system consumable; (b) diverting a portion of an unpurified fluid which could otherwise flow into the system consumable into the model consumable; and (c) analyzing the model consumable to predict the end-of-life of the system consumable. Preferably, the time capacity of the model consumable...
A method for predicting the end-of-life of a system consumable in a system for purifying an unpurified fluid, the method comprising the steps of: coupling a model consumable to a fluid purification system which has comparable characteristics but substantially less capacity than a system consumable in said fluid purification system; diverting a portion of the unpurified fluid which could otherwise flow into said system consumable into said model consumable, the mass flow rate of the diverted portion being controlled by a mass flow controller; and analyzin...
