The invention relates to obtaining a nanofiber membrane by coating a hollow braided rope () with a nanofiber layer (), to the usage of said tubular nanofiber membrane as a support layer membrane, and to the fabrication of forward osmosis membrane by coating the surface thereof with thin composite film (). Particularly, a tubular nanofiber forward osmosis membrane used in water & waste water treatment and desalination processes with high water flux, low reverse salt flux, as well as a low tendency of fouling, and the manufacturing method thereof are disclosed herein.

Manufacturing of a nanofiber forward osmosis membrane with tubular shape

A method of operating osmotic membrane bioreactors (OMBRs) includes the steps of feeding the synthetic wastewater from wastewater tank to the reactor with the help of wastewater pump, and transferring of diluted draw solution through TuNFO membrane to the draw solution tank. The draw solution is diluted through passing of high flux water from the reactor into the membrane by means of osmotic force and vacuum force obtained by operating the vacuum pump at higher velocity than the force pump.
