Impact of Heavy Oil Sewage Components on the Performance of Coagulated Particles

Abstract:

In this paper, the relationship between the components of heavy oil wastewater and thesurface wettability of coagulation particles were studied. The effects of cations (Ca2+, Mg2+, Fe2+,Fe3+), oil content and pH on wettability of coagulated particles surface in heavy oil wastewater werestudied by measuring the contact Angle, and the possible mechanism was discussed. It was foundthat the contact Angle decreased with the increase of pH value. The change of oil content isnegatively correlated with the contact Angle. Surface wettability of coagulated particles arecorrelated with cationic concentration in sewage and standard electrode potential. When cationicconcentration is less than 500 mg/L, surface wettability is positively correlated with standardelectrode potential. When cationic concentration is more than 1000 mg/L, surface wettability ismainly related to the total amount of cationic ions in sewage.
