Abstract
A filtering unit includes a filtering component having inner and outer walls arranged around each other so as to define an inner space between the inner wall and the outer wall, a filtering mesh partitioning the inner space into a pre-filter chamber and a post-filter chamber, at least said pre-filter chamber being circumferentially compartmented in sectors, a divider arranged coaxially with the filtering component and having distinct distribution columns, and a rotary backwashing distributor having a shutter provided with a discharge opening, the rotary backwashing distributor being mounted to rotate so that said discharge opening is periodically and selectively put into communication with each distribution column, whereby each distribution column periodically and selectively establishes communication between the discharge opening and respective ones of the sectors. The rotary backwashing distributor is in direct contact with the divider.
