CoRe Water: from evolution to a revolution in municipal water treatment

Forward Osmosis (FO) does not as yet offer any ready-made solutions, but it does present prospects

The development of a new modular and adaptive physical-chemical concept for the treatment of wastewater remains a big challenge, as shown in the recently completed CoRe Water project within the TKI Water Technology programme. The implemented technology using spiral-wound Forward Osmosis (FO) membranes is susceptible to fouling and clogging and consumes lots of energy. This further understanding is helpful in ultimately arriving at the right form of FO implementation that will make the treatment of our wastewater future-proof.

A wide range of societal developments are confronting the Water Authorities with several challenges related to wastewater. Climate change, the energy transition, the circular economy, increased urbanisation and stricter quality requirements for surface water call for a series of smart solutions. This transition to the way we will be handling our wastewater in the future is being shaped among others by improving effluent quality, cutting greenhouse gas emissions, and recovering valuable resources, water and energy from wastewater. Closely linked to this is the development of the CoRe Water concept, as an innovative, adaptive and modular physical-chemical treatment concept. The concept’s aim is to separate pre-treated wastewater into a clean water fraction and a strongly concentrated wastewater stream.
