Our concept can radically change wastewater management; raw, municipal sewage is fed into a membrane process known as forward osmosis (FO). In the FO process the feed solution is separated by a semi-permeable membrane from the so-called draw solution; the latter is characterized by very high osmotic pressure. The filtration process takes place spontaneously without the need to apply any external pressure due to the concentration gradient existing between the low osmotic pressure feed wastewater and the high osmotic pressure draw solution and the tendency of liquids to equalize their concentration.
As a result of this process, the water flows from sewage to the draw solution which is diluted. Municipal wastewater is converted to a low volume liquid, having high concentrations of organic substances and nutrients. Then downstream processes can be applied to recover energy from sewage through the operation of a low cost and low footprint UASB reactor. The nutrient rich effluent of UASB is valorized in a struvite crystallizer that produces a slow-release fertilizer of high added value.
FORWARD-WATER participated in Water Innovation and Circularity Conference, WICC, held in Athens Greece (7-9/6/2023) with an oral presentation entitled ‘’Investigating the feasibility of combining the FO-UASB process for Energy Recovery from Concentrated Municipal Wastewater’’.
