Stable suspensions of solids in metal salt solutions for use in water treatment

摘要: 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 ten most preferably, about one micron. These used to treat surface waters remove organic materials therefrom. The suspension forms floc includes the materials, which rapidly settles out solution, leaving purified water as supernatant liquid.
