Abstract
Turbulent mixing in a UV system is increased by positioning one or more ring-shaped devices, such as washers, at one or more predetermined locations on the exterior surface of each lamp unit in the system. The washers may have the same or different diameters. Turbulent mixing is also increased by retaining the upstream end of each lamp unit in a ring-shaped device, alone or in combination with washers positioned on each lamp unit exterior surface as described above.
Claims16
A method for increasing turbulent mixing in a UV system immersed in a liquid, said system having a plurality of substantially parallel lamp units, said method comprising the steps of:
- installing a ring-shaped device at a predetermined location on the exterior surface of each said lamp unit;
- and
- flowing the liquid substantially parallel to the plurality of lamp units to cause the ring-shaped devices to provide turbulence in an area between the plurality of lamp units.
A UV system for immersion in a liquid comprising:
- (a) a plurality of UV lamp units;
- and
- (b) a ring-shaped device located at a first predetermined position on an exterior surface of each said lamp unit, for causing turbulence in liquid flowing in a space between the plurality of lamp units.
A UV system for immersion in a liquid comprising:
- (a) a plurality of UV lamp units mounted between upstream and downstream end retainers;
- (b) a ring-shaped device mounted on said upstream end retainer adjacent each said lamp unit, to cause turbulent flow in an area between the plurality of lamp units.
