Abstract

Portable water conditioning systems include a water conditioner having a plurality of conditioning stages including, in a direction of flow of the water through the water conditioner, a reverse osmosis stage having a reverse osmosis membrane, and a deionizing stage. A first sensor is configured to detect a first condition of the water before the reverse osmosis stage and a second sensor configured to detect a second condition of the water after the reverse osmosis stage. The conditions each include (i) a level of total dissolved solids of the water and (ii) temperature of the water. A controller is in communication with the sensors and configured to determine of a percent of dissolved solids that are rejected by the reverse osmosis membrane based on the conditions when backpressure on the reverse osmosis stage is at a known state.
