On the first day of the Aquatech Amsterdam, Allied Waters, BLUE-tec, KWR and Royal HaskoningDHV signed a collaboration agreement for the further development of CoRe Water, a new technology concept that can radically change the treatment of municipal waste water.
The four parties believe it is time for a fundamentally rethought of the current treatment process that are designed to meet effluent standards. Resource recovery should not be a side-line, but the central trust of a production process.
The objective of the agreement is for parties to develop a process that aims to recover a maximum amount of energy and resources from waste water, and to radically cut emissions of greenhouse gases and pharmaceutical residues.

Concentration as first step
CoRe Water stands for an innovative concept: Concentration and Reuse. ‘As a first step, we will concentrate municipal wastewater by a factor of 20 applying forward osmosis,’ says Lex van Dijk, director of BLUE-tec.
The separation results in very clean water of a ‘demi’ water quality which is suitable for reuse in a number of applications. The concentrated stream (1 part of the 20) is then biologically treated – first anaerobically, then aerobically.
Danny Traksel, Business Developer at Royal HaskoningDHV explains: ‘In this way we can recover the maximum amount of energy and valuable components, while making the removal of pharmaceutical residues manageable. We also take huge steps towards limiting greenhouse gas emissions.’
Making the leap
The key technique applied is Forward Osmosis, a relatively new and promising technology which is now beginning to break through in water practice.
‘More than ten years ago, we started researching Forward Osmosis on a small scale and, little by little, we made progress’, says Emile Cornelissen, senior scientist at KWR. ‘Now, I look forward to making the leap to water practice with our partners’.
Van Dijk concludes: ‘With CoRe Water we’re now truly making the step from WWTP to water factory!’
