Die RO-(Umkehrosmose)Anlage (10) hat ein Permeatsammelrohr (48), das an einem Ende mit einem Verteilungssystem für das Permeat verbunden ist, das wenigstens eine Einrichtung zur Reinigung und/oder Desinfektion (32)aufweist. Das Permeatsammelrohr (48), die Reinigungs- und/oder Desinfektionseinrichtung (32) und eine Zirkulationspumpe (27) sind in einem Zirkulationskreis angeordnet.Reverse osmosis plant (60) that is couplable with at least one load, preferably dialysis apparatus to supply high-purity permeate, comprises a raw water supply line (9) that supplies raw water to a filter module (10), whose primary chamber is separated from secondary chamber by semi-permeable membrane. The raw water supply line comprises permeate collecting pipe that is connected with distribution system for permeate, a permeate supply line with at least one connection, and a permeate-return line. The permeate-distribution system comprises at least one device for cleaning and/or disinfecting.

The permeate-distribution system comprises at least one device for cleaning and/or disinfecting, where a concentrate discharge pipe leads away the filter module from the primary chamber. The permeate collecting pipe, the cleaning- and/or disinfecting device and a circulating pump (27) are arranged in a circulating circuit.
