ABSTRACT:
A method of producing U.V. radiation by effecting an electrical discharge such that at least a part of the discharge path is submerged in water. An apparatus for performing the above method comprises two electrodes spaced apart to form a discharge region, a discharge chamber containing the discharge region, means arranged to apply a high voltage across the electrodes, and means arranged to supply water to the discharge region such that at least a part of the electrical discharge is submerged in the water, at least a portion of the discharge chamber being transparent to U.V. radiation. Also, a method of treating a material comprising producing U.V. radiation as described above in a discharge chamber at least a portion of which is U.V. transparent, passing the material through a treatment chamber adjacent the transparent portion of the discharge chamber; and an apparatus for performing the method of treating a material. In some described embodiments the position of an electrode is adjusted in dependence upon the electrical characteristics of the discharge such as to maintain predetermined conditions. In one embodiment an electrode is mounted in the bottom of the discharge chamber which forms the other electrode; water covers the electrode and has a controlled circulatory motion such as to control the height of water over the electrode and thus the submerged discharge path. In another embodiment one of the electrodes is formed by a layer of mercury; an initiating discharge between a third electrode and the mercury or the other electrode to establish a degree of ionisation of the mercury in the vicinity of the discharge region. The main discharge excites the mercury vapour resulting in radiation at 254 nm.
