A grey water processing device for a rail vehicle, the processing device comprising:

• a grey water container including an inlet region, an outlet region and a base defining a base side, said base being higher in said outlet region than in said inlet region;
• a grey water supply disposed in said inlet region;
• a drain disposed in said outlet region for grey water processed in said grey water container, said drain having an opening for passage of processed grey water into said drain, said opening being spaced apart from said base of said grey water container, and said drain having a pipe guided through said base of said grey water container and protruding into said grey water container;
• a slotted filter disposed between said inlet region and said outlet region, said slotted filter having at least one sliding member being movable between a lowered position touching said the base and a raised position raised from said base, and said slotted filter having at least one fixed slotted member;
• said at least one fixed slotted member and said at least one sliding member being disposed relative to each other in said grey water container to form a gap between said at least one fixed slotted member and said at least one sliding member at least in said lowered position of said at least one sliding member to cause grey water in said inlet region intended to be filtered to flow through said gap to reach said outlet region;
• said at least one sliding member having a face facing said at least one fixed slotted member and a resilient lip disposed on said face;
• said resilient lip scraping off adhesions on said face of said at least one fixed slotted member facing said at least one sliding member upon said sliding member moving from said lowered position into said raised position;
• a cleaning outflow disposed at said base side in said inlet region;
• and
• a fresh water supply disposed in said outlet region for supplying fresh water.
