Abstract: The present invention relates to a fluid treatment system comprising: an inlet; an outlet; and a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) an. elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and to a direction of fluid flow through the fluid treatment zone. The present fluid treatment system has a number of advantages including: it can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small 'footprint'; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the fluid treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby obviating or mitigating of breakage of the radiation source and/or protective sleeve (if present). Other advantages are discussed in the specification.

Abstract: An object is to dissolve and remove rust and scale deposits of inorganic compounds formed in a reservoir, in which to store water that requires processing, or in piping, or on a jacket of a UV-lamp without using any chemicals. A photocatalytic water-processing system utilizes a reservoir 11 in which organic and inorganic materials present in water 100 that requires processing the water are decomposed. The system comprises: a circulation path including: a main unit 2 arranged outside the reservoir 11; an inlet pipe 8 connecting to an inlet of the main unit 2; and an outlet pipe 9 connecting to an outlet of the main unit 2; a pump 4 for circulating the water; a filter 5 arranged within the main unit 2; photocatalytic processing means arranged downstream of the filter 5 and including a photocatalyst carrier 7 and a UV-lamp 6; and an electrode unit 3 arranged within the reservoir 11. The water 100 is electrolyzed as a current is applied to the electrode unit 3.

Abstract: A fluid treatment system (100) for placement in a flanged pipe fluid conveyance system. The fluid treatment system (100) comprises a flanged ductile iron pipe fitting (105). The ductile iron pipe fitting (105) comprises: a first flanged opening (110) and a second flanged opening (120) in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow (A) through the first opening (110) and the second opening (120); and a third flanged opening (130) comprising a first cover element (155). The first cover element (155) has connected thereto at least one radiation source (150) assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis. In its preferred form, the fluid treatment system may be advantageously utilized to treat fluid such as water, e.g., municipal waste water, municipal drinking water and the like. The fluid treatment system is particularly advantageous since it utilizes a standard ductile iron pipe fitting (105) and thus, can be readily 'spliced' into existing piping systems. This facilitates installation of the system and also allows for a significant lowering of manufacturing costs of the system.

Abstract: There is disclosed an optical radiation sensor system. The system includes a sensor device (140) and a cleaning device (115). The sensor device detects and responds to radiation from a radiation field (170) and includes a surface (155) that is movable with respect to the radiation field between a first position in which the surface is in the radiation field and a second position in which at least a portion of the surface is out of the radiation field. The cleaning device operates to remove fouling materials from at least a portion of the surface in the second position. The cleaning device may be a chemical cleaning device, a mechanical cleaning device or a combined chemical/mechanical device.

Abstract: The invention relates to a UV-irradiation device for treating fluids, comprising an improved device for cleaning the surfaces of the jacket tubes. The UV-irradiation device comprises a number of lamp units, each having a radiation source and a jacket tube (3) that surrounds said radiation source, the lamp units being essentially cylindrical and a cleaning device, which has cleaning elements (1) that encompass the jacket tubes (3) in the form of a ring. At least one cleaning element (1) is allocated to each jacket tube (3) and the cleaning elements (1) of at least one drive unit can be displaced in the longitudinal direction of the jacket tubes (3). The cleaning elements have an axially delimited annular chamber, which is open towards the surface of the jacket tubes. At least one ring consisting of a rubber-type elastic material lies in said chamber. The internal diameter of said ring in an unstressed condition is less than or equal to the external diameter of the jacket tube.
