| Abstract: | This paper reports on the flocculation of iron, aluminium and humates from Scottish river water by the three major salts in sea water. The molarities of the salts required to precipitate the maximum amounts of Fe, Al and humates decrease in the order: NaCl, MgCl2, CaCl2. The maximum amounts of a species precipitated by the salts are shown to increase in the same order. Chemical and electrostatic interactions are both involved in the flocculation process. |
