Abstract
Stable suspensions can be made from acidic metal salt solutions and finely divided acid-insoluble solid particles that have a particle size of less than twenty-five microns, preferably less than ten microns, and most preferably, about one micron. These suspensions can be used to treat surface waters to remove organic materials therefrom. The suspension forms a floc that includes the solid particles and organic materials, which floc rapidly settles out of solution, leaving purified water as the supernatant liquid.
