A UV disinfection system including at least one UV lamp assembly with a sleeve surrounding a UV lamp and defining an inner volume. The UV disinfection system further includes at least one pressure sensor. At least one non-return valve connects the inner volume of the at least one sleeve to the pressure sensor. The UV disinfection system is configured to detect a sleeve breakage by the resulting change in pressure at the at least one pressure sensor. A break detection device for a UV disinfection system with a pressure detector includes at least one tubing which communicates directly or indirectly with an inner volume of a sleeve surrounding at least one of a UV lamp unit.

A disinfection apparatus and method is provided for disinfecting a fluid. The apparatus elements define three internal container volumes. Fluid is introduced into an entry volume where its flow is conditioned to reduce splash and slow the fluid flow. The fluid is then channeled into a disinfection volume where a disinfection unit delivers a disinfection agent to the fluid. Finally, the fluid exits the apparatus through an exit volume. In one aspect, a sink-trap is disclosed in which wastewater liquid contacts a pair of diverters. The diverters have conditioned contact surfaces that slows and spreads the liquid flow and reduces liquid splash. The wastewater then passes through a UV chamber in which it is disinfected. The liquid then exits the sink-trap. Advanced self-cleaning apparatus are additionally disclosed to clean and disinfect the sink-trap and trapped wastewater. The entire apparatus operates under computer control.

The invention relates to the detection, assessment and mitigation of harmful water-borne bacteria such as cyanobacteria. Multiple apparatus embodiments and variations are described. One apparatus can apply at least one of UV-C irradiation, microbubbles containing ozone and ultrasonic sound to mitigate the harmful water-borne bacteria. The systems and methods of the invention can be applied to bodies of water, including fresh water and salt water, and can be applied to wastewater treatment. The systems and methods of the invention can be used to reduce the concentration of algae directly and can be used to reduce the concentration of nutrients in water that algae use to grow. Methods of mitigation of the harmful bacteria are described that do not involve the introduction of chemicals into the environment.

A system for disinfecting fluid includes a plurality of fluid reactors. Each of the fluid reactors includes at least one UVC LED. The UVC LED includes an LED chip configured to emit UVC radiation and a package coupled with the LED chip. The LED chip has a top surface that defines a chip top surface area. The top surface is formed from a semiconductor material having an index of refraction. The fluid reactor has at least one wall that defines a chamber configured to contain the fluid. The at least one wall has an aperture configured to receive UVC radiation into the chamber. The aperture extends through the at least one wall. The aperture has an aperture area that is (1) smaller than a top surface area of the package and (2) equal to or larger than the chip top surface area.

A mobile washing station includes a base portion and a column that extends vertically from the base portion. An upper portion is supported on the adjustable column and includes a basin, a drain, and a faucet. A clean water tank is in fluid communication with the faucet via a water line. A water pump is designed to pump water from the clean water tank through the water line to the faucet. A wastewater tank is in fluid communication with the drain via a drainage line.

A generator (100, 101, 102, 103, 104, 105, 106, 107, 108, 109) is used for producing a treated oxygen containing gas for treating a body of matter (11). The generator (100, 101, 102, 103, 104, 105, 106, 107, 108, 109) extends along a generator axis and has an axially extending hollow sleeve (12) defining an internal space (14). At least one lid (16) is located at one of the axial ends of the sleeve (12) and a UV light source (18) and at least one magnet (20) are located along the axis.

This disclosure relates to aggregating, neutralizing, and filtering ultra-fine particles in fluids such as air and water. Fluid may be drawn from an ambient environment into a neutralization chamber. Within the neutralization chamber, particles in the fluid may be agglomerated. An acoustic field may be applied to the fluid to agglomerate the particles. The agglomerated particles may be exposed to light. The light may denature or deactivate the agglomerated particles. The agglomerated and inert particles may be passed through a filter. After agglomeration and neutralization, the fluid may be released back into the ambient environment.

The present invention discloses an ultraviolet light-emitting faucet comprising an inlet assembly, an outlet assembly, an operation assembly configured between the inlet assembly and the outlet assembly, and a waterproof light emitting module disposed in the operation assembly. The operation assembly has a conduit and an operation room that communicates, the waterproof light emitting module is disposed in the conduit and capable of emitting an ultraviolet light into the operation room in order to sterilize the water flowing through the operation room.

A solution for irradiating a flowing fluid through a channel with ultraviolet radiation is provided. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation based on the flow rate of the fluid and a user input component can receive a user input for the control system to adjust the ultraviolet radiation. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.
