A method for flocculating finely divided particles suspended in nonpolar liquids, thereby facilitating the removal of these particles by sedimentation or filtration, by treating the contaminated nonpolar liquids with from about 0.01% to about 5% by weight of a flocculant comprising a water soluble organic compound having a cationic quaternary nitrogen or ammonium group. The flocculants useful in the method of the invention are desirably miscible or dispersible in the nonpolar liquid, and a carrier solvent or surfactant may be used to improve dispersibility of the flocculant.
