Abstract

"When the rapid population growth and the environmental effects it brings with it are examined, it is seen that the protection of water resources is one of the most critical issues. 97.5%of the water on earth is found in oceans, seas, and lakes. While fresh water makes up only 2.5%of this amount, 2/3 of this water is glaciers. Only 0.3%of the water covering the earth’s surface is potable water. As population and agricultural and industrial water use increase, the pressure on limited water resources is deepening. Imbalances between supply and demand create a global problem called water scarcity. Water scarcity includes water stress, water shortage or lack, and water crisis. Given that the demand for existing water resources is growing with time, it is obvious that alternative water resources must be supplied. Among these alternative water supply methods, membrane-containing processes are the most popular and have the greatest potential. Especially, membrane bioreactors (MBRs) used in the reuse of wastewater and reverse osmosis processes used in drinking and utility water from sea water take their place as promising processes in worldwide and in our country in creating an alternative water source and their use is becoming widespread. Local and national production of alternative water supply methods using membranes, the importance of which will be felt much more in the near future, is another significant issue that needs to be focused."
