Color Removal from Dye Wastewater: A Review
Decolorization of waste waters containing dye impurities is also important, as color is prominently visible which affects the water transparency ethics requiring the wastewater to be treated. The color removal process for dye wastes consists of either concentrating the color into sludge or the complete

Colour Removal. Removing Colour from Wastewater. Employing water treatment methods which effectively remove colour from water and wastewater, can not only help to avoid fines, but can also save money by allowing wastewater to be reused during manufacturing processes. natural tannins along with synthetic chemical dyes. In order for the
DYE WASTEWATER TREATMENT: REMOVAL OF REACTIVE DYES USING
Synthetic waste were studied in order to determine the effectiveness of various inorganic and organic coagulants for removal of color of the dye-stuff from the water. It was hoped that use of pure dye solutions would make it possible to obtain information about the color removal efficiency of coagulants for individual dye.
Dye removal reached higher than 97% after 5 min. With the current density of 25 Am 鈭?, this amount of dye removal was achieved at a longer time (13 min). At 15 Am 鈭? current density, dye removal remained below 75% at all electrocoagulation times. The experiment was rerun with aluminum used as anode.

Biosorption of Reactive Dyes: A Review
Development of treatment technologies to alleviate water pollution has been a challenging and demanding task for researchers. Furthermore, synthetic dyes fabricated of complex aromatic structures turned out to be a great hazard as they impart color to water reservoirs making them abhorrent for human use. Reactive dyes being water soluble prove difficult to be eliminated by conventional
2008) and others. Chemical, biological and physical methods for dye removal are discussed in detail as below. 1.1.4.1 Chemical Methods Breakdown of bonds which aid in decolorization and degradation of dyes is the basic step in removing color and toxicity of dyes. Examples of some chemical methods are
