Because of low pressure required, even manual pumping can filter water successfully to achieve the potable water quality. 因為水力過(guò)濾器所要求的壓力小，在受災區域沒(méi)有電力供應的情況下，通過(guò)手動(dòng)水泵實(shí)現正常過(guò)濾，保證受災人員的飲用水安全。
Barrett said she shares LalibertZ's concern about potable water, and also is excited about the many scientific experiments that are under way on the space station. 巴瑞特說(shuō)，她和拉利伯特同樣關(guān)切飲用水安全，并對即將在太空站所進(jìn)行的諸多科學(xué)計畫(huà)倍感興奮。
