Nutrient and energy recovery technologies
Mathematical models have become very important tools for technology design, optimizing performance, and process troubleshooting as they are both time and cost efficient. Although a number of models of waste and wastewater treatment facilities have been developed and applied extensively, these state-of-the-art models lack the inclusion of key fundamental physico-chemical processes that play a major role for nutrient and energy recovery. Critical elements to be dealt with include accurate descriptions of acid-base reactions, slow precipitation kinetics, liquid-gas exchange, and ion pairing in the complex mixture of chemical entities that the recovery systems in place deal with. Moreover, nutrient recovery models should provide information on the physicochemical characteristics (e.g. purity, particle diameter, density, etc.) of the recovered products under varying conditions (input composition, pH, temperature, reagents, etc.) in order to determine and control their fertilizer properties.
Nutrient management and pollution
Models are useful tools to evaluate environmental impacts associated with nutrient management in cropping systems and to predict them correctly. Moreover, models can be used to predict the risks of heavy metal or microbial contamination in food production.
SeLow is specialized in modelling and optimization of waste (water) treatment systems, resource recovery technologies, and nutrient dynamics in the environment. The modelling work is based on a detailed chemical solution speciation, combined with physicochemical and biological reaction kinetics.
