Abstract
An ultraviolet water treatment plant is provided in which individual ultraviolet lamp units are loosely and retractably located within frames supported in a water treatment channel. Individual frames supporting arrays of parallel lamp units may be removed from the channel, and the lamp units may be individually disengaged from the frame and disassembled for lamp replacement. The frames have unitary plug connectors to a power supply arranged so that the plug of a frame must be disengaged from the supply before that frame can be removed from the channel. The level of water in the channel is controlled according to the rate of flow, and the lamp units are selectively energized according to whether they are immersed so as to match the irradiation provided to the rate and cross section of the flow.
