ABSTRACT:
A fluid treatment apparatus comprises two titanium mesh filters (12,22) connected in series across a flow passage. Each filter (12,22) is irradiated by UV light from respective lamps (13a,13b,23a,23b), so as to kill any micro-organisms trapped on the filters. Backwashing means (18,19,28,19) are provided for backwashing each filter in succession whilst fluid flowing along the passage is filtered by the other filter. In this manner micro-organisms are unable to pass through the apparatus untreated.
