Abstract
The application status of ultrafiltration technology in drinking water treatment plants of China was summarized. Ultrafiltration was applied in five forms:( 1) ultrafiltration-reverse osmosis( UFRO) process;( 2) shortened process with ultrafiltration as the core part;( 3) traditional process with sand filtration replaced by ultrafiltration;( 4) advanced treatment process with ultrafiltration;( 5) drinking water treatment process with ultrafiltration in rural areas. The application status,characteristics, cost,and process of ultrafiltration technology in drinking water treatment plants of China were analyzed. The existing problems in application of ultrafiltration technology as well as future development directions of ultrafiltration technology and combined ultrafiltration process were proposed.
