Appl. No.:

7/131016

Inventors:

Robert Blum - Harleysville PA

International Classification:

B01D 1300

US Classification:

210641

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.

International Classification:

B01D 3704

US Classification:

210742

Abstract:

An energy efficient water purification system which maintains critical operating temperatures for effective reverse osmosis. The system includes hot and cold water inlets providing a flow of heated feed water, a regeneratable pre-treatment system for treating the heated feed water, a reverse osmosis machine for receiving the flow of pre-treated feed water heated to a given temperature to purify the feed water and discharge impurities in a discharge stream and feed the purified feed water to an outlet for end use, and a valve to control the temperature of the heated feed water entering the pre-treatment system, and an energy conserving apparatus comprising a valve arrangement which interrupts the heated water flow into the pre-treatment system and substitutes fresh unheated feed water during regeneration.
