- Abstract: Estrogens are endocrine-disrupting chemicals (EDCs) that enter waterbodies via wastewater. Because of this, some countries are creating legislation aimed at developing processes to degrade EDCs in wastewater-treatment plants. Estrone and estradiol are the estrogens found in high concentrations in waterbodies. Some processes in literature suggest using the enzyme laccase to degrade EDCs. This work mathematically models EDCs degradation by laccase in an enzymatic membrane reactor (EMR). The models were built from the mass balances of EDCs and active enzymes in EMR, including Michaelis Menten kinetics and a parameter coupling the enzyme activation, deactivation, and loss by the outflow. Experimental data from literature were used in the models' regressions. The experiments considered three experimental conditions to evaluate two process parameters: EMR residence time and O2 pulse frequency. The models' assessment considered the following statistical tests: Student's t to evaluate the parameters' significance; Akaike Information Criteria to select the best models; and R2 to evaluate the models' fit. Results show the best assessed kinetic models were able to represent degradation in an EMR, and the best operation conditions were a residence time of 4 h and an O2 pulse frequency of 0.5 h. The methods and mathematical models presented in this manuscript can contribute to wastewater plant design for reducing contamination by EDCs in waterbodies.
