Abstract

The apparatus is a gas filled lamp or electrical discharge assembly for use as a liquid purifier. The lamp is powered by high voltage AC, but has no metallic electrodes within or in contact with the gas enclosure. Cooling liquid is pumped through the volume inside the inner quartz cylinder where an electrically conductive pipe spaced from the inner cylinder is used to supply the cooling liquid and act as a first electrode. The gas enclosure is enclosed within but spaced from a housing which is connected to operate as the second or ground electrode of the circuit and through which the treated fluid flows. The first electrode is electrically isolated from the source of cooling liquid. A method for treating a liquid with a radiation generating lamp is also provided and includes providing a treatment chamber which comprises the first and second electrodes and the gas enclosure containing a gas capable of generating an electrical discharge and positioned between the electrodes.
