The process comprises treating the liquor with 250to 430 mg/l chlorine which removes 20 to 70 percent of the color and produces achlorine residual in the liquor. The chlorine-treated liquor is mixed with a small volume ofuntreated thermal conditioning liquor to remove the chlorine residual, and thedechlorinated mixture is returned to the treatment plant influent for additionaltreatment.
