A desalination system includes a vertical column with a lower end submerged into a body of liquid to be treated. The column has a dark-colored outer surface able to absorb electromagnetic energy, and at least one vacuum compressor is connected to provide a vacuum pressure in the vertical column such that the liquid is drawn into the vertical column through openings in the vertical column. A condensing dome has a main shell and that receives vapor of the liquid in the vertical column via a vapor port joining the vertical column and the condensing dome. A wind-driven outer turbine surrounds the main shell of the condensing dome and draws outside air into a space around the main shell of the condensing dome. A tank is connected to the condensing dome via a pipe and receives desalinated liquid from the condensing dome.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium an energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The energy modulation agent has a normal predominant emission of radiation in a first wavelength range outside of a second wavelength range (WR2) known to produce the change, but under exposure to the applied initiation energy produces the change. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

The ice maker may include an auger at least partially surrounded by a casing. The casing may be in fluid communication with the water storage volume to receive water from the water storage volume. The ice maker may further include a sealed refrigeration system in thermal communication with the casing. The pump may be in fluid communication with water storage volume for actively flowing water from the water storage volume to the ice maker. The ultraviolet light source may face the water storage volume to selectively direct ultraviolet light into the water storage volume.

A ballast water treatment apparatus includes a filtering device including a filter for filtering seawater, an ultraviolet irradiation device that irradiates the seawater filtered by the filter with ultraviolet light, a first path for supplying the seawater filtered by the filtering device to the ultraviolet irradiation device, a discharge water path for discharging the seawater remaining in the filtering device, a first valve provided in the first path, a second path for supplying the seawater flowing from the ultraviolet irradiation device to a ballast tank, and a control device that closes the first valve and cleans the filter by using the seawater introduced into the filtering device before the seawater filtered by the filtering device is supplied to the ultraviolet irradiation device.

A distribution system for a wetting liquid supplied to spinning nozzles of an air-jet spinning machine includes a supply pipe for the wetting liquid supplied to the spinning nozzles. At least one UV light emitting diode is arranged in the supply pipe, wherein the UV radiation emitted by the UV light emitting diode passes through the wetting liquid to disinfect the wetting liquid.

A distribution system of a wetting liquid for spinning nozzles of an air-jet spinning machine comprising a supply pipe (21) of the wetting liquid (1) to the spinning nozzles (3) of individual workstations, characterized by that in the supply pipe (21) of the wetting liquid (1) is arranged at least one UV light emitting diode (5) to disinfect the wetting liquid (1), whereby the UV radiation emitted by the UV light emitting diode (5) passes through the wetting liquid (1).

An ultraviolet water purifier includes a water filter including a water inlet connector for guiding in a fluid, a filter element for filtering the fluid from the water inlet connector and a filtered water outlet connector for guiding out the filtered fluid, a housing including an intake water connection portion for guiding in the filtered fluid, a purified water output portion and a water passage in communication between the intake water connection portion and the purified water output portion, a hydroelectric generator drivable by the flowing of the filtered fluid in the water passage to generate electricity and to provide generated electricity to a germicidal UV lamp for sterilizing the filtered fluid that flows out of the water passage through the purified water output portion.

A pond filter includes a housing having a fluid inlet and a fluid outlet, and a UV filter chamber disposed in a fluid flow path between the inlet and the outlet. The UV filter chamber includes a UV lamp arranged for illuminating water flowing therethrough. The UV filter chamber has a fluid channel through the UV filter chamber being defined between a tube and a shroud portion of the chamber. The chamber has at least one sealing arrangement including a sealing assembly for mounting the tube to the shroud portion and sealing means including an O-ring seal which is retained between a nut and a bushing of the assembly. The seal is urged by a nut and bushing into sealing contact with the tube as the nut is engaged onto the shroud portion.

A composite water purification apparatus and method thereof are provided. The composite water purification apparatus includes a container, a sacrificial anode, a photocatalyst anode and a cathode. The container is employed for receiving liquid including water and gas. The photocatalyst anode includes a photocatalyst for conducting a photocatalytic reaction. The cathode is electrolyzed with the sacrificial anode and the photocatalyst anode. The cathode, the sacrificial anode, and the photocatalyst anode are immersed in the container to contact the liquid. The present invention enhances the purity of the water, while prolonging the service life of the sacrificial anode.
