Improving inlet water quality for washing machine by using electrochemical application

Nowadays the accessibility to clean water is important because of this reason the economical, social and technological challenges attract attention in worldwide. While the human population is increasing, the consumptions of water sources are increasing, too. The water softening technologies are developed with the purpose of obtaining usable water in different areas. The scope of water usage is large and it is divergent from developing country to developed country. In the industrial, agricultural and domestic areas are common usage areas for water.When the technologies are reviewed, different driving forces such as the difference in concentration, temperature, pressure and electrical potential are effective on the separating process. Thermal, membrane and electrochemical process are commonly used in the water treatment area. The new technologies are investigated and for eliminating the disadvantages of present technologies the hybrid ones are developed. Sometimes two or more driving forces are used in these hybrid technologies.As a new developed technology in water treatment area, the membrane capacitive deionization technology is used as a modified type of capacitive deionization. The porous carbon electrodes are used in capacitive deionization technology. The impurities are adsorbed in the electrodes when the electrical potential is applied to the system. The positive voltage is applied to the system in the adsorption step and for the reproducibility of sytem the negative voltage is applied to the system so that the desorption process is actualized. Adding ion selective membrane to the capacitive deionization system give advantage in terms of ion removing efficiency. There is no chemical waste in system and it does not require high temperature or pressure conditions in process step. In these respects the membrane capacitive deionization system has advantages. The used water quality in industrial applications such as textile, chemical, white good industries is important, too. The performance of household appliances are affected by inlet water quality. The water plays different role in washing process so the different methods for improving used water quality are tried to be used. The most effective water parameter for washing process is hardness ions because of attracting on detergent so reducing the cleaning performance. The purpose of this work is learning the effect of improved water quality on the natural and chemical sources consumption in washing machine process.
