The development of a mathematical model for the bioextraction of the critical raw material magnesium from mine waste using acidithiobacillus caldus by Raeburn, Yael

“…Using the previously de-termined mineral reactor conditions (0.5% solids loading, τ1 = 14.6 days, pHi = 1), complete extraction of magnesium was achieved at a stock reactor mean residence time (τs) ≥ 10.4 days, establishing an optimal threshold at Vs : 1.4V1. This set-up achieved the same performance as the CSTR with acid in the feed while eliminating the need for synthetic acid. pH control was achieved using a PI controller for the rate of acid addition, for which ITAE tuning parameters were optimised for both disturbance (Kc = 40.7 mol−1.L, τI = 12 h) and set-point changes (Kc = 20 mol−1.L, τI = 326 h). …”

Experimental evaluation of the effect of thermal heat and pressure pre-treatment on primary sludge anaerobic digestion by Mwidu, Aaron

“…The AD model of Sötemann et al. (2005) also comprises a stoichiometric section that is sequential to the part which calculates sludge breakdown (i.e., BPO utilized) via hydrolysis kinetics. This stoichiometric section is used to calculate the changes in H2CO3* Alk., FSA, partial pressure of the biogas and digester pH from the concentration and composition of the BPO utilized. …”
