Abstract
Disclosed is a method for the break-up of at least one emulsion and separation of the light and heavy phase with at least an de-emulsification rate of more than 9% in only one apparatus within less than 5 min by applying at least one time dependent electrical field. The electrical field is a high frequency singular alternating current field with an electrical field strength between 2,000 and 100,000 V/m and a frequency between 12,000 Hz and 200,000 Hz. The present invention relates furthermore to a method for the treatment of at least one emulsion by applying at least one direct current field and at least one high frequency alternating current field.
