%X The textile industry uses high amount of water and generates wastewater that requires effective wastewater treatment technologies. Textile industry in Turkey is an advanced industry particularly in Bursa. During the dying process of fabrics and the fibres a lot of water, synthetic dyes and various chemicals are used, and consequently wastewater is produced that contains complex pollutants with different chemical structure. In particular, dyes that have high water solubility and low fixation rates hydrolyse before they are fully fixed, which results in high amount of waste dye. Decreased light permeability due to the colour caused by the waste dye prevents photosynthetic activities and oxygen depletion occurs. Furthermore, the presence of toxic and mutagenic dyes in water bodies adversely affect aquatic life. Releasing them into the sewage system without treatment can cause problems in biological processes of urban wastewater treatment plants. Therefore, there is a need for innovative, cost effective and efficient wastewater treatment technologies for the treatment of wastewater containing dyes before they are released to the water systems. Electrocoagulation is known to be an effective method especially in colour removal from textile industry wastewaters. In this study, as an effective method for colour removal from waters electrocoagulation was applied to a disperse dye (Disperse Blue 79), which is in a colloid form in a dye solution, and to a reactive dye (Reactive Yellow 160), which has an anionic character and is dissolved in water. After a 10 minutes experiment period with 0.1 A current intensity %92.45 color removal rate was obtained for Disperse Blue 79 whereas for the Reactive yellow 160 color removal rate was only %54.84. Study results shows the importance of dye type in color removal with electrocoagulation method
