反渗透膜元件透过系数的试验与数学求解

Experimental and mathematical method for permeability coefficients of reverse osmosis membrane elements

明确了反渗透膜元件两透过系数求解所需的函数形式、幂项数、试验组数、试验点位、变量归一、回归分析及回归效果检验等一系列试验与数学过程,并给出了某支膜元件两透过系数求解的试验数据及其计算实例。

A series of testing and mathematical method for the both of water and salinity permeability coefficients of the reverse osmosis （RO） membrane elements, such as the function form, the items number of power, the group number of tests, the test points, the normalized variables, regression analysis and examination of regression effect, etc. were described. The experimental data and calculation process for permeability coefficients of one RO membrane element were depicted.
