Water Science and Technology Special Issue on


Water Resource Recovery Modelling (WRRMod21)

 

Our society is transitioning fast into the digital age, spurred by development of cheap and new sensing technology, breakthroughs in computing, and development of efficient algorithms for optimization. This transition is also visible in the field of wastewater treatment and is driving new model developments, especially by exploiting the large data sets available with many utilities.

The 7th Water Resource Recovery Modelling 2021 Seminar was held in Arosa, Switzerland. The WRRMod series is designed to share and discuss cutting-edge advances and innovative practices in the modelling of Water Resource Recovery Facilities (WRRF). The seminar offers a unique opportunity for practitioners, utilities, engineers, and researchers to get together and critically discuss pioneering modelling concepts and practices.

WRRMod2021 featured a strong session on the hot topic of ‘data-driven models and digitalization’ and exhibited sessions on modelling of new process units (e.g., aerobic granular sludge), modelling of the nitrogen cycle, and integrated/plant-wide modelling.

In this Special Issue on the Water Resource Recovery modelling published in Water Science & Technology journal, six relevant studies that highlight recent promising model developments were selected.
