Abstract: A water purification system for treating grey water from household appliances such as baths, showers, vanity basins and washing machine (11-15) has branch-off pipes (29-33) from the usual drain pipes (17-21) these branch-off pipes lead to a storage tank tank (35). The branched off water is filtered by a screen filter (51) then circulated by a pump (53) in series to a heater (55). The system also includes a sediment filter (57), a carbon filter (59), color filter (61), an ultraviolet radiation unit (63), and hence via a shut-off valve (71), to a storage tank (73). The purified grey water can be used for car-washing, and garden and lawn irrigation. The system can be retrofited to an existing home or installed in a new home.

Abstract: Various embodiments of photoreactors are disclosed which have at least two irradiation chambers with a window therebetween. Ultraviolet radiation is introduced into one of the chambers at a side opposite the window so that it passes through that chamber, through the window and into the other chamber. The fluid medium to be purified is passed through the chambers and subjected to the radiation while in the chambers. The flow of the medium is through the chambers in series in some embodiments and in parallel in others. An embodiment is disclosed wherein a recirculation line is established around the reactor with the recirculation being continuous or intermittent. When intermittent the purified fluid medium also is drawn off intermittently, between the periods of recirculation. In some embodiments the amount of radiation traversing all the chambers is monitored. If the monitored amount drops below a given amount, the apparatus is shut down. Alternatively, the rate of flow of the medium is adjusted, based on that monitored amount, with the rate of flow increasing or decreasing, respectively, in response to increases or decreases in that amount.

Abstract: A method and apparatus for continuously purifying a fluid by the emission of ultraviolet rays characterized by a body with a series of spaced, parallel, elongated, cylindrical radiation chambers extending therethrough, and a plurality of elongated, interconnecting chambers having a height substantially less than the diameter of the radiation chambers, a plurality of elongated, ultraviolet ray emitting lamps removably mounted in jackets in the radiation chambers, respectively, and extending from the front to the rear of the radiation chambers. Fluid to be purified is continuously received in an elongated chamber and spread into sheet-like flow attitude and thence passed serially and transversely between the lamp jackets and the walls of the radiation chambers, the walls being in close proximity to the jackets to maintain sheet-like flow for a substantial distance around the periphery of the lamps, and the fluid is maintained in sheet-like flow between adjacent radiation chambers by passing through the interconnecting chambers, and thence the purified liquid is discharged from the last of the radiation chambers.

Abstract: An apparatus and method are provided wherein a liquid to be irradiated is formed into the shape of an unsupported thin stream; the stream is irradiated from a source of radiation which is disposed in spaced relationship to the liquid stream. The apparatus has numerous utilities such as, for example, disinfecting contaminated liquids by subjecting them to ultraviolet or infra-red radiation. Oxygen can be supplied to the radiation zone of the apparatus in the case of ultra-violet radiation to produce an oxidizing atmosphere of ozone in contact with the liquid. The apparatus possesses numerous advantages over previously described apparatus as discussed in greater detail in the attached specification.
