Abstract
The instant invention relates to a process for removing dispersed matter from water which comprises, providing a flocculated salt selected from the group consisting of iron, aluminum and Group IIA of the Periodic Table of the Elements in said water, adsorbing at least a portion of said dispersed matter on said flocculated salt, providing an oil, adsorbing said flocculated salt on said oil, and separating said dispersed matter from said water along with said flocculated salt and said oil. This process especially relates to the separation of dispersed matter, e.g., oil, from sea water, wherein said Group IIA flocculated salt is provided by adjusting the pH of said sea water with a basic material to precipitate magnesium hydroxide. Alternatively, a basic carbonate salt may be added to sea water to precipitate calcium carbonate from sea water as the flocculated salt. The pH is adjusted to at least 7 but preferably not over 10.5 so as to eliminate further treatment of the water, to meet environmental quality standards, prior to discharge. The pH of sea water is preferably adjusted by addition of lime.
