Abstract: Textile industry wastewater is one of the most important hazardous wastewater species threatening the environment and public health. Textile wastewater with a high proportion of dyestuffs accumulates in the receiving environment, disrupts the aesthetic appearance of the waters and reduces the light penetration. Reduction of light penetration and dissolved oxygen leads to a decrease in the living organism population and restricts the use of water resources. It is also known that certain types of dyestuffs have toxic properties. Textile wastewaters containing even very small amounts of dyestuffs have high dispersion rates and can spread to largely water bodies and threaten the environment and human health, when discharged without treatment. While adsorption, filtration and chemical processes are preferred for color removal, biological activated sludge systems are used for COD removal from colored wastewaters, generally. Today, nanotextile membrane processes are used for more efficient treatment. However, compared to other treatment methods, it can be concluded that electrocoagulation (EC) processes are more suitable for color and COD removal from textile industry wastewater. Electrocoagulation, which has a wide application area in wastewater treatment, makes a major contribution to the economy of concentrated waste discharging industries. Moreover, these processes can greatly reduce the pollutant load. In the studies carried out by the electrocoagulation process of textile industry wastewater, up to 100% color removal was determined. In addition, high levels of chromium, COD and turbidity removal efficiencies were observed from tannery industry wastewater with high Cr content by EC process.
