| Abstract: | The conception and isolated mechanism of nanofiltration are introduced. A process is designed by using nanofiltration to treat circulating cooling water of a power plant aiming at the raw water quality. Operation parameters of pretreatment and membrane are also designed. On the basis of this, taking original water of 30 000 m3/d as an example,the investment and cost of nanofiltration membrane process are analysed. The economic efficiency of the project is compared. The results show that it is a kind of economic, feasible circulating cooling water treatment technique. |
