Abstract
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.
