Experimental determination of the mixing requirements for solid suspension in pharmaceutical stirred tank reactors
… been fully studied, such as the minimum impeller agitation speed, N_{js}, to just suspend finely divided solids. In this work, N_{js} was experimentally obtained for a number of different pharmaceutically-relevant agitation systems including vessels with different types of bottoms (torispherical …

Mixing, mass transfer and energy analysis across bioreactor types in microalgal cultivation and lipid production
… surface aeration coupled with mechanical agitation as an alternative. An airlift photobioreactor was used as a base for comparison with two novel, surface aerated reactors: oscillatory baffled and wave photobioreactors. The three bioreactors were compared in terms of power input, mixing, …

Novel experimental method for the determination of the minimum agitation speed for solids suspension in flat-bottomed stirred tank reactors
Knowledge of the minimum agitation speed, Njs, required to suspend finely divided solids in vessels stirred by an impeller is a critical parameter to properly operate industrial tanks in a large number of industrial operations. The most common experimental approach to measure N_{js} is that of …

An electrochemical and leach study of the oxidative dissolution of chalcopyrite in ammoniacal solutions
… are ferric sulphate, chloride and ammoniacal systems. The ferric sulphate system does not work well under atmospheric conditions, except in combination with thermophilic microorganisms, whereas the chloride system has only recently been evaluated more seriously for heap leach processes. The …
