这种方法需要用高压泵使海水通过一种不能渗透盐的薄膜，从而淡化海水。
This employs high-pressure pumps to force the water from brine through a membrane that is impermeable to salt.
结合反渗透海水淡化高压泵的能耗状况，合理选择了万吨级反渗透海水淡化高压泵的泵型，提出了一种轴向吸入节段式高压多级泵的新型结构型式。
Considering the energy consumption of the HP-pump for SWRO, a reasonable type of high pressure pump was selected, and a new structure of the axial suction segment multistage pump was proposed.
