Application of liquid extraction for treatment of wastewater from edible oils production

Abstract

The structure of an emulsion formed in wastewater from edible oils production has been investigated. The type of emulsifier has been determined and the method of emulsion destruction has been proposed, providing further quality treatment of wastewater via liquid-extraction method. The resulting equilibrium and operating lines of the process were received. The number of transfer stages has been determined. The mathematical model of liquid-extraction wastewater treatment was built. Its solution allows to predict the kinetics of wastewater extraction when implementing the technology in practice. The equipment was selected to design flowsheet of wastewater treatment using a liquid extraction.
