Abstract

The present invention provides a system for predicting prefilter life, the system comprising a water treatment device and a control module, wherein, the control module is configured to: record values of flowrate (FRn) sensed by the flow sensor, wherein FRn is a direct function of the water treatment system performance; plot a graph of FRn values against Vn values; store a predetermined value of flow rate FRmin; wherein FRmin is a value of FRn, a value less than FRmin indicates end of prefilter life; and extrapolate the graph to deduce Vn at (FRmin), the deduced value of Vn at FRmin is the estimated volume (VE) indicating prefilter life.
