ABSTRACT:
The present invention is directed to methods and apparatus for purifying water wherein a highly dispersed, hydrophobic flocculant is produced in situ. In the preferred methods, a dispersion of a water-insoluble, metallic soap is produced in situ by the reaction of an aqueous solution of a water-soluble, multivalent metal salt with an aqueous solution of a water-soluble, alkali soap. The apparatus of the present invention includes a first mixing chamber for producing in situ an aqueous dispersion of a hydrophobic flocculant. The apparatus further includes a second mixing chamber in fluid communication with the first chamber and a flocculation/separation basin. The hydrophobic flocculant is evenly dispersing within the contaminated water by introduction into the second chamber through a high pressure pump and sparger. As the hydrophobic flocculant forms in the flocculation/separation basin, it entrains other impurities, thus producing purified water which is withdrawn from the basin through a clean water outlet.
