Patent ID: 8366883

Claim:
A water vapor distillation system comprising: a compressor upstream from a condenser, the compressor having a rotatable housing; at least one capacitive level sensor for measuring the level of water in the compressor; a controller for receiving information from the at least one capacitive level sensor; and at least one variable flow valve coupled to the at least one capacitive level sensor and controlled by the controller, wherein the at least one capacitive level sensor, the controller and the at least one variable flow valve maintain the level of water in the compressor in the water vapor distillation system, wherein the water vapor distillation system further comprising: means for distilling source water to produce product water; means for measuring the conductivity of the product water; means for determining whether the conductivity of the product water is below a pre-set level; and if the conductivity of the product water is below a pre-set level, means for triggering a signal mechanism to pump a volume of at least one additive into the product water.
