超纯水设备主要是经过四项过滤的：精密滤芯、活性炭滤芯、反渗透膜等。他们都是有相对寿命的，精密滤芯和活性炭滤芯实际上是对反渗透膜的保护，如果它们失效，那么反渗透膜的负荷就加重，寿命减短，如果继续开机的话，那产生的纯水水质就下降，随之就加重了反渗透膜的负担，则反渗透膜的寿命就会缩短。最终结果是加大了超纯水设备的使用成本。
Ultrapure water equipment is mainly filtered through four items: precision filter element, activated carbon filter element, reverse osmosis membrane, etc. They all have a relative life. The precision filter element and the activated carbon filter element are actually the protection of the reverse osmosis membrane. If they fail, the load of the reverse osmosis membrane will be increased and the life will be shortened. If you continue to start the machine, the quality of the pure water produced will decline, and then the load of the reverse osmosis membrane will be increased, and the life of the reverse osmosis membrane will be shortened. The final result is to increase the use cost of ultra pure water equipment.
