Verfahren zur Herstellung einer Gasentladungslichtquelle sowie Gasentladungsröhre

Process for rendering grey water fit for re-use

The process involves discharging the grey water to a holding tank which has a force feed to an incorporated germicide section which allows water to travel in both directions. In a process and assembly to render grey water fit for further use, the water is discharged to a holding tank where it is held allowing particles to settle out. The holding tank incorporates a force-feed to an incorporated germicide section, through which the water passes at least twice. The germicide unit is so constructed that on first arrival in the holding tank, the water passes through the germicide section in a first direction. When water is drawn from the holding tank, the water first passes through the germicide section in the reverse direction.

Uv irradiation apparatus

In a memory unit 6, there is stored a correction table for each candidate value of an output set value of each of LED units 2. If UV rays have ever been emitted so far by the LED units 2, each of which is formed of a plurality of LED chips 8, then a PLC 5 acquires, upon setting of a output set value by an operation unit 53, a correction value corresponding to a cumulative emission time up to a previous emission, from the correction table of the output set value. Thereafter, the PLC 5 sets the magnitude of the power supplied to each of the LED units 2 using the acquired correction value. If an output set value different from a previous output set value is set, the PLC 5 obtains the correction value starting from the cumulative emission time upon modification. As a result, the UV irradiation apparatus enables power consumption necessary for emission of UV rays to be reduced, and UV ray output to be kept constant regardless of the cumulative emission time, even if the output set value is modified.

Methods for the treatment of ballast water

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.
