Abstract
A liquid purification system comprising a housing with inlet and outlet for the flow of the liquid to be purified. A source of ultraviolet is mounted within the housing surrounded by a sleeve of ultraviolet-transmissive material such as quartz. A rod mounted for reciprocal movement is mounted in the housing and extends out of the housing. On the rod is mounted wiper assemblies each one of which consists of tear-shaped plate to surround the sleeve, a washer of suitable material on the plate to make contact with the sleeve for wiping the outer surface of the sleeve as the rod is reciprocated, and a securing device to hold the washer in place. Pins with press-on nuts are employed to sandwich each wiper assembly together.
