The daily output of China's 121 seawater desalination projects reached more than 1 million tonnes in total by the end of 2015, according to an official report released on Wednesday.
The report on seawater utilization in 2015 issued by the State Oceanic Administration (SOA) said China's daily output represented less than 1.25 percent of the world's daily production volume, which totaled 86.55 million tonnes as of the end of 2015.
Of China's desalinated water, 67.14 percent has been used for industrial purposes, and the rest for residential use, said the report.
Lei Bo, an SOA official, said China is trying to expand financial sources for seawater desalination projects and aims to use desalinated seawater on a large scale by 2020.
