1. A vapor distillation apparatus comprising:
a source liquid input;
a blowdown liquid output;
a product water output;
a compressor comprising an intake and an output;
an evaporator condenser apparatus fluidly connected to:
the source liquid input via a source liquid valve;
the blowdown liquid output via a blowdown valve and a blowdown reservoir, the blowdown valve downstream of blowdown reservoir and the blowdown reservoir including a level sensor;
the product water output via a product valve; and
the compressor intake and the compressor output;
the evaporator condenser transforms source liquid into steam and blowdown liquid, the steam delivered to the compressor and transforms compressed steam from the compressor into product water;
a control system for controlling the vapor distillation apparatus comprising a plurality of controllers and a plurality of states including but not limited to;
a heat exchanger prime state wherein said source liquid valve is opened at a predetermined duty cycle;
a run state wherein the liquid vapor distillation apparatus produces product water;
the run state having a blow down controller varying a duty cycle of the blowdown valve based on a signal from the level sensor; and
a source flow controller varying a duty cycle of said source liquid valve based on the signal from the level sensor.
