It is described a vessel (101, 401), comprising: an internal space (109, 409) for harbouring plural arrangements (113) for filtering water (251); a port (111, 411) at a bottom side for allowing entry of air (123, 423) into the internal space (109, 409) partially filled with water during a procedure for cleaning the plural arrangements (113, 413) for filtering water; an air distribution structure (121, 421) enclosing the port (111, 411) and adapted to distribute air (123, 423) introduced via the port for reaching the plural arrangements (113, 413) for filtering water across a larger area than, in particular five times, a cross sectional area of the port (111, 411). |
