Aeration removes iron, manganese, CO,. As can be seen from Fig. A solvent or detergent is generally used to conduct stain removal and many of these are available over the counter. The raw water is rich in natural organic material producing correspondingly high color levels. Permanent hair color works two ways: it deposits new pigment molecules and it breaks down existing molecules. Removal of color-bearing organic material resulting from kraft effluents was shown to be an important economic consideration in surface water treatment. However, this results in the formation of disinfection by-products.

Color removal by coagulation process by use of alum and ferrous sulfate was > 99 % and COD removal is approximately 70 %. Advantages of Electrocoagulation process for color removal in water treatment plant, they are using Electro Chemical (Electrocoagulation) process to remove the Color, COD, BOD and electrical conductivity by 80-90% in COD/BOD aspect and 20-35 % in Electrical Conductivity side.. Physico-chemical treatment, Coagulation and flocculation are traditional methods for the treatment of polluted … Figure 2: Need to go for chemical color removal process after biological treatment for complete removal of color. However, if there is the need for hair color removal much before the stipulated time, there are many hair color removal products in the market. Following are some important water treatment methods employed for removing color, taste and odor. The removal rates of cations and color were very rapid during the initial stages of the stage-wise process. Before treatment Furthermore, a tremendous reduction of removal performance was recorded for color fromthe 2500 mg/L to the 3000 mg/L dose. Coagulation-flocculation has received considerable attention for yielding high pollutant removal, especially color removal. This is a challenging process which requires the right products, good information and realistic expectations.
