20110289665 | DEVICES FOR USE IN THE TREATMENT OF FLUIDS - A urinal outlet device including a hollow perforated cage for retaining one or more effluent treatment blocks within the cage. The cage is provided with spacing means, in the form of spikes on the inside of the cage for holding the blocks at a spaced distance from an inside surface of the cage. The cage, spacing means, are dimensioned, shaped and positioned relative to the blocks and an outlet flow of effluent from the urinal so that, in use of the device, the blocks are spaced from a surface of the urinal whilst enabling the one or more blocks to be exposed to the flow of urine. Where the urinal is a water flushable urinal, the blocks are held substantially out of the main flow of flushing water flowing to the outlet of the urinal to prolong the life of the blocks without impairing their ability to disinfect and deodorise the urinal. | 12-01-2011 |
