Abstract: A wiper assembly is provided for cleaning the reactor tubes of an ultraviolet-light reactor. The wiper assembly is positioned inside a reactor chamber of the ultraviolet-light reactor. The wiper assembly includes a wiper that has a circular opening sufficiently large to accommodate a reactor tube. A wiper blade is formed on the wiper circumferential of the opening and being deflected such that when the reactor tube is positioned through the opening, the blade engages the outer surface of the reactor tube. The wiper is formed of a plastic material. The wiper is connected to a platform positioned within the reactor chamber. The platform supports the wiper in the reactor chamber such that the reactor tube extends through the opening in the wiper. According to one aspect of the invention, at least one rod is connected to the platform. The rod extends out of the reactor chamber. The rod can be moved from outside the reactor chamber for mechanically reciprocating the platform along the length of the reactor tube in the chamber, whereby, the wiper blade slides along the outer surface of the reactor tube to wipe off at least some of the fouling that may have accumulated on the outer surface of the reactor tube. According to another aspect of the invention, the platform is supported by a plurality of floats to move with the fluid level in the reactor chamber.

Abstract: An ultraviolet liquid purification system includes a purification chamber having banks of ultraviolet lamps distributed therein for applying germicidal ultraviolet radiation to the liquid flowing through in said chamber. Ultraviolet photocell detectors are located in said chamber to detect the level of ultraviolet radiation transmitted through the quartz jacket housing the ultraviolet lamps and through the liquid being purified. Indicator means produce an alarm signal when the total ultraviolet radiation transmitted through the liquid drops below a preselected level. In addition, a light conducting fiber is provided for each ultraviolet lamp having its input endface located at the ultraviolet lamp and its output endface at a display panel whereby identification of a particular ultraviolet lamp that has failed may be easily detected. Photocell detector means are provided to detect the light output at the output endface of the light conductor fiber and to produce an alarm signal when said light output fails. An in-place cleaning system for cleaning the interior of the purification chamber is also provided.

Abstract: Apparatus for the purification of liquid, such as water, by exposing the same to ultraviolet lamp, embodying means forming an annular passageway through which water may flow in surrounding relation to an electric lamp of a type producing ultraviolet light and ultraviolet light-responsive means for shutting off the flow of water therethrough in response to a decrease in the intensity of the ultraviolet light passing through the water when such intensity falls below a predetermined value. The apparatus includes a protective tube of quartz glass surrounding the ultraviolet lamp and wiper means movable in response to the turning off and on of the flow of water through the apparatus to wipe the external surface of the quartz tube. Means is also provided for preventing the formation of clouded areas on the glass of the lamp due to the positioning of the wiper means at one location surrounding the lamp during long periods of nonoperation of the wiper means while the lamp is on. Means is provided for preventing the wiper means from interferring with the flow of ultraviolet light flowing to the light responsive means by which the flow of water is cut off.

Abstract: A self-cleaning ultraviolet wastewater disinfection unit and method are provided. The disinfection unit has a wastewater treatment chamber comprising a UV lamp for treating/disinfecting the wastewater. A plurality of pieces of media may be positioned in the treatment chamber. When wastewater is present in the chamber, gas is injected into the wastewater through a gas inlet conduit. The gas agitates the pieces of media in the wastewater to cause the pieces of media to rub against the UV lamp unit to remove matter that has accumulated on the UV lamp unit. The removal of accumulated matter on the UV lamp and other surfaces in the chamber may improve the efficiency and effectiveness of the disinfecting unit. Furthermore, the cleaning operation may be performed automatically at scheduled periods to increase the time between major cleanings of the unit.
