METHOD FOR FLOCCULATING FINELY DIVIDED SOLIDS SUSPENDED IN NONPOLAR LIQUIDS

A method for flocculating finely divided particles suspended in nonpola r liquids, thereby facilitating the removal of these particles by sedimentatio n 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...

Beschreibung
Zusammenfassung:	A method for flocculating finely divided particles suspended in nonpola r liquids, thereby facilitating the removal of these particles by sedimentatio n 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 compou nd 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.
