Abstract
Demulsification is one of the continuous problems in wastewater treatment and this
emulsion was found during petroleum and petrochemicals industries. This process
carried out demulsification of kerosene/water emulsion in electrical cell which contains
two horizontal Al screens (anode) and horizontal Al square plate (cathode) at the cell
bottom. Electro-coagulation is carried out in an electrolytic cell with Al anode, the
anodically dissolved AI+++ neutralize the negative charge present on the colloidal
particle (or kerosene DROPlets) with a consequent destabilization of the colloidal solution
or the emulsion.
Demulsification of oily waste water by electrocoagulation takes place within 30 min.
The present work shows that the removal percentage increases with decreasing initial
concentration of kerosene, decreasing NaCI concentration, decreasing temperature of
emulsion, increasing current density and the maximum removal percentage within pH
range 6-7.
Key words; demulsification, kerosene, electrocoagulation
