Color removal by coagulation process by use of alum and ferrous sulfate was > 99 % and COD removal is approximately 70 %. A solvent or detergent is generally used to conduct stain removal and many of these are available over the counter. The WSM process is being examined with funding from Calgon Carbon and an alternative cheaper process is being investigated which gives better color removal. The FO process removed COD at a higher rate (59%) than O 3 (33%) while color removal was similar (89% and 91%, respectively). Results obtained were in the range of 86 to 95% removal for caustic extract effluent and whole mill effluent. Before treatment Currently, breakpoint chlorination is used at the water treatment plant to control the color problem. The amount of ozone can vary depending on a number of factors: how much color was removed in the biological process, the type of dye used, where ozone is applied in the process, etc. Hair color removal is sometimes necessary. Hair coloring is very popular today, with over 75% of women coloring their hair and a growing percentage of men following suit.
