<p>The filtration procedure consists of maintaining a minimal water circulation inside at least one ultraviolet filter, varying the filtered water flow according to the use made of the pool by means of two alternating circulation systems. The filtration apparatus consists of two conduits (100, 200) with pumps (P1, P2) having different output rates and linked to circulate water through an ultraviolet sterilizer (F). It has a third conduit (300) fitted with a compressor (330) delivering water under pressure to a robot cleaner. The inlets and outlets (110, 160, 350) of the different conduits are located above water level.</p> |
