A liquid treatment system comprising at least one ultra-violet (UV) treatment lamp

摘要

A liquid treatment system (2; 2’; 102; 202) comprising:- at least one ultra-violet (UV) light treatment lamp (6) arranged within an elongated protective UV-transparent sleeve (8; 8’) provided along a central longitudinal axis A, said sleeve (8; 8’) having an outer surface (10; 10’) and an essentially circular crosssectional shape; and- an elongated reactor (12; 12’; 12”) configured to receive said sleeve (8; 8’), whereby an elongated liquid treatment chamber (4; 4’) for receiving liquid to be treated, is provided between an inner surface (14; 14’) of the reactor (12; 12’; 12”) and the outer surface (10; 10’) of the sleeve (8; 8’); wherein said liquid treatment system (2) further comprises- at least one elongated cleaning device (16; 16’) provided side by side with the sleeve (8; 8’) within the liquid treatment chamber (4; 4’) and along at least a part of the length of the elongated sleeve (8; 8’),wherein said at least one cleaning device is compressed towards the outer surface (10; 10’) of the sleeve (8; 8’) by the reactor (12; 12’; 12”), and wherein at least one of the sleeve and the reactor is configured to rotate around the longitudinal axis A such that the at least one cleaning device (16; 16’) will be touching and cleaning the outer surface (10; 10’) of the sleeve (8; 8’) over essentially the whole circumference of the sleeve (8; 8’).
