ABSTRACT:
Contaminated water is purified by introduction into a filter, filtering the water, accumulating the partially purified water delivered from the filter, heating the collected water to a temperature near its boiling point, reintroducing the collected water into the same filter, and continuously repeating the filtering, accumulation and heating steps with attendent further purification, until the degree of contamination of such water has dropped below a predetermined level. A predetermined portion of the purified water may be distilled subsequent to the completion of the purification operation, and the distilled water is collected for eventual consumption. An arrangement for performing the above method includes a vessel (9) have a filter (7) arranged at its upper region (20) (9a), and a lid (3) removably supported on the vessel and may include a jet deflector (100) for providing more uniform flow of slugs and water vapor to the filter inlet. An electric resistance heater (10) arranged either inside of or external to the vessel (FIG. 2), and a riser tube (16), which may have a steam collecting bell (14) at its lower end, delivers water slugs and water vapor to the filter. The riser tube may also be inside of or external to the vessel and include a mechanical pump (53) in place of thermal pumping action. The vessel may communicate with a steam condensing receptacle (45) to provide distilled water (46). A control system (111) may be provided for automating the purification cycle and may further incorporate an additional storage tank (126) for delivering purified water in a substantially continuous manner.
