A filtering unit includes a filtering component having a pre-filter chamber circumferentially compartmented in sectors, a filtering medium and a post-filtering chamber, a divider arranged coaxially with the filtering component and having distinct distribution columns, a cover and a rotary backwashing distributor having a shutter provided with a discharge opening. The rotary backwashing distributor is mounted to rotate so that the discharge opening is periodically and selectively put into communication with each distribution column. Each distribution column periodically and selectively establishes communication between the discharge opening and respective ones of the sectors. The filtering unit further includes a dividing plate arranged between the cover and the rotary backwashing distributor, the dividing plate being detachably secured with respect to the cover and having apertures opening into the distribution columns. The shutter abuts the dividing plate at least around the discharge opening.
