Abstract:
The invention relates to a system for treating gases and/or liquids with radiation or for detecting radiation in gases and/or liquids, including at least one optical system and a reactor. The reactor has a hollow body shape which includes lateral surfaces, connecting parts, and an inner chamber which may be open to the front and rear sides, through which a medium flows or in which the medium is present. The reactor is designed, at least partially, in the form of a radiation reflector and is divided into first and second functional areas. This enables a particularly homogeneous radiation distribution in the inner chamber of the reactor, which increases the efficiency of the treatment or detection. Also, due to this arrangement, the system is more compact.
Abstract:
There is described a fluid treatment system comprising: (i) a fluid inlet; (ii) a fluid outlet; and (iii) a fluid treatment zone in fluid communication with the fluid inlet and the fluid outlet. The fluid treatment zone comprises a housing within which is disposed a fluid separation section (the separation section may include a single separation device or a combination of two or more similar or dissimilar separation devices) and a fluid radiation section in fluid communication with one another. The fluid separation section removes solids in the fluid and the fluid radiation section irradiates the fluid to deactive microorganisms in the fluid. The fluid separation section and the fluid radiation section are configured to have a substantially common fluid flow path which significantly reduces the space or footprint requirement of and/or significantly reduces hydraulic head loss (pressure drops) in the overall fluid treatment system while allowing the two sections to perform their respective functions.
Abstract:
Provided is a standalone integrated water treatment system for a distributed water supply including a filter input, a coagulation system in operative connection with the filter input, wherein the water is subjected to a coagulation process to create pin floc from suspensions in the water. A maturation buffer tank in operative connection with the coagulation system aggregates floc in size within the water. A spiral separator separates the water into two water streams, a first stream of water having most of the floc removed, and a second stream of water which includes a concentrated amount of the floc. An optional filtration system is configured to receive the first stream of water and perform a filtration operation thereon. A sterilization system is configured to perform a sterilization operation on the first stream of water. The water is then output from the sterilization system as potable water.
Abstract:
The present invention relates to a portable water purification system by means of UV LEDs. Provided according to the present invention is a portable water purification system by means of UV LEDs comprising: a support member; a plurality of LEDs mounted on the surface of the support member; a solid filter provided with a through-path into which the support member is inserted; and a cover, attached to one end of the solid filter, for sealing the through-path of the solid filter.
Abstract:
Disclosed fluid purification systems can comprise a treatment vessel configured to contain a fluid to be purified, a source of ultraviolet radiation with at least 50% of its emitted spectral energy at wavelengths between 315 nm and 400 nm positioned exterior to the treatment vessel, and a portion of a wall of said treatment vessel that is substantially transparent to the ultraviolet radiation emitted by the source of ultraviolet radiation, located so that at least 50% of the ultraviolet radiation propagates through the substantially transparent portion of the wall and is configured to propagate into fluid to be treated within the vessel for the purpose of killing or disabling pathogenic microorganisms in the fluid.
Abstract:
A light source, with electrodes of alternating polarity attached to a substrate in an excimer ultraviolet (UV) lamp, for generating a plasma discharge between each of the electrodes. The shape of the substrate can shape and control the plasma discharge to reduce exposure of materials susceptible to attack by the halogens. The electrodes can be located such that the plasma discharge occurs in a region where it produces less contact of the halogens with the vulnerable areas of the lamp enclosure. The materials, such as the electrodes, substrate, and envelope, can be selected to withstand corrosive materials. In another embodiment, a plurality of sealed tubes, at least some of which contain an excimer gas are positioned between two electrodes.
Abstract:
The present disclosure is generally directed to devices and methods of treating aqueous solutions to help remove or otherwise reduce levels, concentrations or amounts of one or more contaminants. The present disclosure relates to a method of which includes the application of a constant current or a pulse width modulation duty cycle to at least one counterelectrode (e.g. cathode) and at least one photoelectrode (e.g. anode) provided or arranged around at least one UV light source in a housing adapted to also receive, contain and/or circulate fluid or aqueous solution.
Abstract:
Provided is a purifying apparatus, which includes ultraviolet lamps and an ozone lamp having different wavelengths from one another and disposed in tubes to remove bacteria, VOC, bad odors in water or air, and these tubes are arranged in a serial or parallel way. Folds are formed at inner ends of the spiral photocatalytic sheets which are in contact with the lamps and the respective lamps are inserted into to increase the contact area with air or water and the one with the lamp, thereby preventing the lamp from being damaged. The purifying apparatus includes: an outer case having an inlet and an outlet; a spiral photocatalytic sheet to be inserted into the outer case; a UV lamp to be inserted into the spiral photocatalytic sheet, wherein folds are disposed at an inner side of the spiral photocatalytic sheet where a space for inserting the UV lamp is formed.
