Abstract:
A method for purifying a water process stream whereby a precipitating agent is added to the water process stream to elevate the process stream pH to at least 10.5 to drop out precipitates which form separated solids comprising at least one of calcium precipitate, magnesium precipitate, barium precipitate, strontium precipitate, and silica precipitate. The separated solids are then coagulated and removed from the water process stream so as to yield a purified water process stream.
