摘要： A self-regulating FO system is disclosed comprising a container containing a source water supply, a forward osmosis membrane element located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, an osmotic pump element also located within the container comprising an area of osmotic membranes, an osmotic agent inlet and a drink outlet, and an osmotic agent tank located above the container. The osmotic agent tank comprises a feed tube connected to an outlet located on the bottom of the osmotic agent tank. The feed tube communicates with the osmotic agent inlet of the forward osmosis membrane unit and the osmotic agent inlet of the osmotic pump element. A return tube communicates with the drink outlet of the osmotic pump element and a port near the top of the osmotic agent tank.

摘要： A forward osmosis water transfer system is disclosed which recycles water from an incoming wastewater stream into an outgoing dilute process brine stream. The system includes a saturated brine stream, a first portion of which is diverted to form a saturated process brine stream and a second portion of which is diverted to at least one forward osmosis membrane. The at least one forward osmosis membrane moves water from the incoming wastewater stream into the incoming diverted saturated brine stream thereby creating an outgoing concentrated wastewater stream and the outgoing dilute process brine stream.
