A model for the simulation of the SHARON process: pH as a key factor

By Albert Magrí Aloy, Lluis Corominas, Helio López, Elena Campos Pozuelo, Marilos Balaguer, Jesús Colprim and Xavier Flotats Ripoll


The SHARON process permits the partial nitrification of wastewaters with high ammonium content and coupled with the Anammox process represents a more sustainable alternative for N removal than a typical nitrification-denitrification. A mathematical model describing a continuously aerated SHARON reactor for the treatment of landfill leachate is presented. Haldane kinetics are used in both steps of the nitrification since ammonium-oxidizing and nitrite-oxidizing organisms are inhibited by their own substrates. Special attention is given to pH because it is a key factor, implementing an algorithm for its calculation. A preliminary calibration of the model using synthetic feed is presented.Postprint (published version
