Patent ID: 7648684

Claim:
A device for disinfecting liquids, the device comprising a generally tubular member formed by a wall of UV opaque material defining a reactor chamber, the opaque wall having an annular end surface at each end, a UV radiation unit in the reactor chamber, a pre-chamber adjacent one end surface, the pre-chamber including a bottom wall having an interior surface axially spaced from its adjacent end surface, the bottom wall having an axially extending connecting element connected to the outer surface of the opaque wall inwardly of its adjacent end surface to form an annular space there between, the connection between the bottom surface and the axially extending connecting element being located outwardly of its adjacent end surface to form an annular gap, the connecting element communicating with a fluid opening located inwardly of its adjacent end surface whereby the annular space, the annular gap and pre-chamber form a flow path between the fluid opening and the reactor chamber, the flow path being configured to provide a uniform distribution of liquid inside the reactor chamber.
