TL;DR: In this paper, the breaking of O/W emulsions of commercial soluble oils using CaCl 2 and AlCl 3 as coagulants is reported and the results show good agreement with the electric double layer theory and the Schulze-Hardy rule.

TL;DR: The effect of pH and crossflow velocity on the ultrafiltration of a model metalworking o/w emulsion was studied in this article, where a vegetable oil as the base oil and a mixture of anionic and non-ionic surfactants as emulsifiers were used.

TL;DR: In this article, the esterification kinetics of lactic acid with methanol without addition of catalyst and catalyzed by ion-exchange resins are presented, and the effect of catalyst type, stirrer speed, catalyst size, catalyst loading, initial reactant ratio, and temperature on reaction kinetics is evaluated.

TL;DR: In this paper, small amounts of a coagulant salt (CaCl 2, in the concentration range 0.01-0.5 M) were added to promote emulsion destabilization and to improve centrifugation.

TL;DR: In this article, an integrated membrane process for producing apple juice and apple juice aroma concentrates is proposed, which involves the following operations: a membrane reactor to clarify the raw apple juice, reverse osmosis (RO) to preconcentrate the juice up to 25°Brix, pervaporation (PV) to recover and concentrate aroma compounds, and a final evaporation step to concentrate apple juice upto 72° Brix.
