Abstract:
A water purification apparatus comprising at least: (a) one or more water purification components to provide a purified water stream, preferably having a conductivity of less than 1 μS/cm; and (b) a stepper motor (35) to control the dispense of the purified water stream (28) from the water purification apparatus. Stepper motors can provide very fine and accurate control of the dispense of the purified water stream from the water purification apparatus, which control is unaffected by the flow or flow rate of the purified water stream.
