NON-FLUSHING URINAL |
摘要 |
<p>A urinal arrangement for flushless hygienic operation has a sealing trap with a bend portion having a bore of not more than 25 mm. The bore size produces "plug flow" through the trap so that liquid retained in the trap as a seal is displaced in use by new liquid without significant mixing of new and displaced liquid. The small bore reduces the exposed surface area of the retained liquid forming the seal.</p> |
