Abstract:
The discreteness of three detection indexes about RO membrane elements is analyzed. The concept of the optimization of installation position of membrane elements with different detection indexes in system flow is proposed. The total differentiation-integer computing method(TDCM) for the optimization of membrane element position is described. The effectiveness of for reducing permeable salt rate via the optimization of element position is determined. And the stability of total differentiation-integer method for the optimization program of element position is verified while the operation parameters, such as feed water temperature,etc. are changing.
