Abstract: The present disclosure relates to antiscale dispersant compositions. The compositions may include various components. The compositions may be used in connection with gray and/or black water processing in a coal gasification system. The compositions are useful for inhibiting the deposition of various materials, such as calcium carbonate, calcium phosphate, iron, aluminum, silicate, calcium sulfate, and any suspended solids in the water.
