A normal flow filtration system having a housing with one or more filters contained within a bowl and attached to the outlet of the system. Liquid enters the bowl, contacts the surfaces of the one or more filters. Impurities are trapped in the filter and the filtered liquid flows through to the outlet. Parameter(s) such as flow rate, transmembrane pressure drop and/or time are measured and when met, filtration ceases. A backflushing occurs through the filter(s) so as to remove the impurities from the filter. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the filter(s) can be used to provide a lateral washing of the filter(s). The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is then restarted.

The invention relates to a device (10) for separating a heterogeneous mixture of matter into at least one retentate and one filtrate, comprising a housing (12) which is subdivided into a chamber for the heterogeneous mixture (20) of matter having at least one feed (14) and a filtrate chamber (21) having at least one outlet (16), a filter unit (22) which comprises at least one filter element (24), wherein the filter unit (22) is arranged in the chamber for the heterogeneous mixture (20) of matter, and a rinsing system (46, 47, 50, 50′) for cleaning the filter unit (22),
wherein the rinsing system (46, 47, 50, 50′) has at least one rinsing port (46, 47) which is constructed so as to introduce a stream, oriented tangentially to the shell surface (54), of a first washing medium into the chamber for the heterogeneous mixture (20) of matter. The invention further relates to a method for cleaning a filter unit.
