Abstract
A novel separator assembly for a spiral flow reverse osmosis apparatus is provided. In one embodiment, the separator assembly comprises a central core element comprising at least one permeate exhaust conduit and at least one concentrate exhaust conduit. Each exhaust conduit defines an exhaust channel and one or more openings allowing fluid communication between an exterior surface of the exhaust conduit and the exhaust channel, said exhaust conduits independently defining a cavity between said conduits. The cavity is configured to accommodate a first portion of a membrane stack assembly comprising at least one feed carrier layer, at least one permeate carrier layer, and at least one membrane layer. A first portion of the membrane stack assembly is disposed within the cavity, and a second portion of the membrane stack assembly is wound around the central core element and forms a multilayer membrane assembly disposed around the central core element.
