Abstract
A method and apparatus predict the organic carbon content of water discharged from a water purification system. Water is directed from a water source across, for example, a source of ultraviolet light of the water purification system under substantially steady-state conditions. A reference mode is established, whereby a reference-mode resistivity change is determined. A purification-mode is then established, whereby a purification mode resistivity change is measured. The reference-mode resistivity change and the purification-mode resistivity change are then combined to obtain a purified value which is associated with the carbon content of water discharged from the water purification system, thereby predicting the carbon content of water discharged from the water purification system.
