Continuous biorefinery process intensification: lignocellulosic biomass pretreatment, syngas microbubble mass transfer, CFD hydrodynamics, and membrane CSTRs.
Resolve the pressure-volume scaling paradox in stirred bioreactors: liquid head hydrostatic gradients (ρgh), bubble expansion, pCO2 accumulation, and P/V.
Compare bioreactor sparger types: drilled hole pipe, sintered frit & microsparger. Learn orifice velocity limits, dual-sparging, and kLa scale-up rules.
Derive fed-batch exponential feeding rates, suppress acetate overflow, and implement closed-loop DO-stat/pH-stat PAT control for high-density fermentations.
Hydrodynamic guide to gas hold-up and gassed power draw in aerated bioreactors. Michel-Miller correlations, impeller cavity regimes, and motor sizing formulas.
Predict and optimize volumetric mass transfer coefficient (kLa) in high-density bioreactors. Derivations of Van ‘t Riet correlations and dynamic gassing-out.
Decentralized wastewater treatment systems are increasingly vital in regions where centralized municipal sewer infrastructure is economically unfeasible, geographically challenging, or operationally unreliable. Rather than relying…
