Özet:

A quarter of the world’s population lives in places where water is physically scare, and globally one in three people endure this water shortage. Unsustainable levels of consumption have led to local water scarcity and have significantly impacted freshwater ecosystems. Meeting the increasing water demands caused by population growth and industry development reduces the available water resources. In many arid and semi-arid areas, it is difficult to provide the large amounts of water needed for industrial, agricultural, recreational and drinking applications. With proper treatment, the recovered wastewater can meet various water quality requirements. Depending on the level of treatment, recycled water can be used in many applications to meet many water demands, such as agricultural and landscape irrigation, industrial processes, toilet flushing, or groundwater basin regeneratio. Although populations continues to increase, the overall water balance must be kept in check. More people mean more fresh water, which means more wastewater. The awareness that water recycling is the only solution that can be given to the worls’s growing water needs is increasing every day. In this study, the water potential in the world and in Turkey, the importance of water recovery, the recovery techniques of wastewater, some studies on the reuse of treated wastewater, and the public opinion on the reuse of treated wastewater are included. Studies have shown that the recovery of wastewater is possible with various treatment methods, but more studies are needed on the reuse of treated wastewater.
