Reuse of wastewater for agricultural irrigation
Supervisors: Mohad Mousavi-Nezhad and Gary Bending
Wastewater reuse for agricultural irrigation is an option to deal with water scarcity and associated threats to food security. Investigations show that treated wastewater may contain micro and nano-pollutants. What is to be explored is the capacity of the soils to act as a filter for purifying wastewater from pollutants. Predicting the filtering capacity of the soils requires a firm scientific foundation for the characterization of basic mechanisms associated with reactive pollutant transport in porous media, and a robust understanding of all relevant processes and properties across the spectrum of relevant length and time scales. This project aims to develop and use machine learning algorithms that quantify the rate of interaction between the micropollutants and soil termed sorption rates.

The project brings together all aspects of the mathematical, scientific and software-design training programme provided by HetSys, as well as the richness of the inter-disciplinary expertise within the Centre. The project requires development of surrogate models to evaluate reaction rates in heterogenous soils (PX912), uncertainty quantification (PX914) and robust software engineering (PX913) to successfully achieve the desired outcomes.
This project benefits from the significant levels of inter-disciplinary expertise within the supervision team (Dr Nezhad: geostatistics, stochastic modelling techniques and model calibrations, and Prof. Gary Bending: the fundamental science related to the chemical reaction process). Since one of its key objectives is to train students to span disciplinary boundaries, HetSys provides an ideal environment for this project. A central focus will be development of modelling in the presence of uncertainty which is related to the heterogeneity of soils and also the study of interactions for multiscale transport and reaction processes. A main outcome of this project will be to develop new Research Software which is well-structured and documented, so that it will both have a long life and can be extended in future.
