Development and application of innovative technologies for drinking water quality assurance in China

Abstract

The continuously deteriorating quality of source water is threatening the safety of drinking water in China. Various efforts have been made to update water treatment processes to decrease the pollution problems of drinking water, such as protection of drinking water sources, enhancement of conventional treatment processes, and development of new or advanced treatment technologies. This paper reviews a variety of protection and remediation methods for drinking water sources, development and application of drinking water treatment technologies, new technologies for special pollutants removal from groundwater, and the latest research progress on water distribution systems in China. treatment plant improvement is the key to ensure the quality of drinking water. There have been many researches on innovative treatment technologies in China and they have been applied in quite a number of water treatment plants. These innovations include key technique development and combination of technologies in the scope of economic optimization. On the basis of water quality from the plant, the distribution system is also important. This paper describes the latest development in the above respects.
