Geometric parameters influencing production of O/W emulsions using flat metallic membranes and scale-up

► Impeller design and liquid height have important influence on droplet size. ► The optimal ratio between the continuous phase height and the tank diameter is equal to 1.0. ► Baffles do not improve membrane emulsification performance. ► Impeller tip speed is the scale-up parameter in stirred tank membrane emulsification.
