APPARATUS AND METHOD FOR DIRECT OCEAN OUTFALLS USING FORWARD OSMOSIS WITH DOUBLE ACTIVE LAYER

摘要

The present invention uses the seawater as the osmotic pressure inducing solution to induce osmotic pressure between the raw water and the seawater, so that the separated treated water is discharged into the seawater, so that a separate induction solution for inducing osmotic pressure is not required and the induction solution and the treated water The present invention relates to a marine discharge apparatus and method using a double active layer forward osmosis membrane, which does not require a separation process. The marine discharge apparatus using a double active layer forward osmosis membrane according to the present invention is a raw water chamber for storing raw water, which is a filtration target, and a lower portion of the raw water chamber. In addition to being suspended in the sea, and comprises an osmosis membrane for separating the raw water into concentrated water and treated water through the osmotic pressure between the raw water and sea water, the treated water separated by the forward osmosis membrane is discharged to the ocean , The forward osmosis membrane, the osmosis membrane frame of the porous material, the upper and lower portions respectively provided on the upper and lower osmosis membrane frame Layer, the active layer and the bottom is constituted by the osmosis membrane comprising a support layer provided in the frame, the upper active layer, the active layer and the lower supporting layer is characterized by comprising a non-cellulose-based polymer.
