ABSTRACT:
An energy efficient dialysis system which requires a minimal amount of energy to operate and maintains critical operating temperatures for effective reverse osmosis and dialysis. The system includes a hot fluid inlet for causing a flow of washing fluid, a reverse osmosis machine for receiving the flow of washing fluid at a first given temperature to filter the washing fluid and discharge impurities in a discharge stream, a plurality of kidney machines receiving the filtered washing fluid to remove contaminants from a body fluid at a second given temperature, a heater adjacent to the entry of the kidney machine to change the temperature of the filtered washing fluid from the first given temperature to the second given temperature, and a valve to control the temperature of the washing fluid entering the reverse osmosis machine; an energy conserving apparatus comprising a heat exchanger for receiving the discharge streams from the reverse osmosis and kidney machines and a cold fluid inlet to introduce fresh washing fluid through the heat exchanger.
