纯净水设备能否长久正常运行
重要的是维护，设备维护的细心，设备就得心应手。所以，在纯净水设备的运行时应该注意不要损坏机器。在纯净水设备的操作中应该注意
The most important thing for the long-term normal operation of purified water equipment is maintenance. Careful maintenance of equipment makes it easy to operate. Therefore, attention should be paid not to damage the machine during the operation of purified water equipment. Attention should be paid to the operation of purified water equipment
1.防止滤料进入反渗透装置：选择合适的过滤器出水装置，防止过滤器漏砂漏活性炭；选择合适的活性炭，防止使用过程中脱粉。
1. Prevent filter material from entering the reverse osmosis device: Select a suitable filter outlet device to prevent filter sand leakage and activated carbon leakage; Choose appropriate activated carbon to prevent powder removal during use.
2.以自来水为水源的大型纯净水设备最好设立独立的供水系统，这样既可以保证供水系统的稳定运行，又可以减少RO系统启停时对全厂供水管网造成的瞬间冲击。当RO装置直接从原水管网上取水时，应设置高低压保护设施，因为大多数自来水管网压力波动较大。
2. It is best to establish an independent water supply system for large-scale purified water equipment that uses tap water as the source of water. This can ensure the stable operation of the water supply system and reduce the instantaneous impact on the entire plant water supply network caused by the start and stop of the RO system. When the RO device directly draws water from the raw water pipeline network, high and low pressure protection facilities should be installed, as most tap water pipelines have significant pressure fluctuations.
3.首先应考虑药剂与药剂之间的兼容性，其次应考虑药剂与膜材料的兼容性。例如，RO系统中经常同时使用混凝剂，助凝剂，杀菌剂，还原剂和阻垢剂。由于天然水中的胶体一般带负电荷，所以通常使用带正电荷的阳离子型混凝剂。为了防止R0装置结垢，RO的进水端几乎都考虑了投加阻垢剂的措施，这些阻垢剂几乎都是带有负电荷的。因此，应避免阳离子型混凝剂与阴离子型的阻垢剂发生反应，防止反应生成的胶体化合物在膜面沉积。
3. Firstly, the compatibility between reagents should be considered, and secondly, the compatibility between reagents and membrane materials should be considered. For example, in RO systems, coagulants, coagulants, fungicides, reducers, and scale inhibitors are often used simultaneously. Due to the negative charge of colloids in natural water, cationic coagulants with positive charges are usually used. In order to prevent scaling of the R0 device, measures have been taken to add scale inhibitors at the inlet of RO, which are almost all negatively charged. Therefore, the reaction between cationic coagulants and anionic scale inhibitors should be avoided to prevent the deposition of colloidal compounds generated by the reaction on the membrane surface.
