1.雙級反滲透：

      原水(shui)(shui)（自來水(shui)(shui)、地表水(shui)(shui)、地下(xia)水(shui)(shui)）加壓送(song)(song)至(zhi)預處理(li)系(xi)統(tong)(tong)粗過(guo)濾，再進入精密過(guo)濾器過(guo)濾后，通(tong)過(guo)一(yi)級(ji)高壓泵加壓送(song)(song)至(zhi)一(yi)級(ji)反(fan)(fan)滲(shen)透系(xi)統(tong)(tong)，該系(xi)統(tong)(tong)產(chan)出的(de)水(shui)(shui)再由二(er)(er)級(ji)高壓泵加壓送(song)(song)至(zhi)二(er)(er)級(ji)反(fan)(fan)滲(shen)透系(xi)統(tong)(tong)，生產(chan)出產(chan)品(pin)水(shui)(shui)，稱(cheng)為雙級(ji)反(fan)(fan)滲(shen)透。
