Development of mathematical models for sedimentation processes, primary sludge fermentation, two-stage nitrification, acid-base processes, precipitation processes, sulphurogenesis and filtration. The group has developed global models that incorporate the main physical, chemical and biological processes that take place in a WWTP, both in water and sludge lines. These models are: Biological Nutrient Removal Model No. 1 (BNRM1) and Biological Nutrient Removal Model No. 2 (BNRM2). The latter model is implemented in the DESASS software.
