This invention describes a method for predicting when a water treatment system's filter bed will run out of capacity. It works by continuously monitoring the recent average water flow through the system, adjusting this rate with a special weighting factor, and then using that adjusted rate to estimate how much life is left in the filter. This prediction can then be used to automatically send an alert or request a replacement for the filter.
Why it matters: The increasing maturity and cost-effectiveness of edge computing and IoT platforms since 2022 make it more practical to deploy distributed sensor networks that perform local calculations and transmit predictive maintenance data to central servers, as described in the claims.
