When operating a wash plant, environmental regulations typically require that the effluent of the silt/clay-laden dirty wash water is contained on site. As this wash water may contain 10% ultra-fine solids, it cannot be sent back to the plant for reuse unless the silt and/or clays can be separated from most of the water.
