反渗透设备讲解反渗透纯净水设备停运保护

由于生产的波动,反渗透纯净水设备不可避免地要经常停运,短期或长期停用时必须采取保护措施,不适当地处理会导致膜性能下降且不可恢复。

Due to the fluctuation of the production, RO pure water equipment inevitably will often outage, short-term or long-term disabled must take measures to protect, inappropriate treatment may result in irreversible decline and film properties.

短期保存适用于停运15d以下的系统,可采用每1~3d低压冲洗的方法来保护反渗透纯净水设备。实践发现,水温20℃以上时,反渗透纯净水设备中的水存放3d就会发臭变质,纯净水生产设备 大型反渗透设备 小型反渗透设备有大量细菌繁殖。因此,建议水温高于20℃时,每2d或1d低压冲洗一次,水温低于20℃时,可以每3d低压冲洗一次,每次冲洗完后需关闭净水设备反渗透装置上所有进出口阀门。

The short-term 15d service applies to preserve the system below, can be used for every 1 ~ 3D low pressure washing method to protect RO pure water equipment. In practice, the above the water temperature is 20 ℃, RO pure water equipment in the water storing 3D will odor, pure water production equipment for large reverse osmosis equipment for small reverse osmosis equipment, a large number of bacteria. Therefore, suggested that the water temperature is higher than 20 ℃, every 2D or 1D low pressure washing once, the water temperature is below 20 ℃, can each 3D low pressure washing once, each time after washing the need to close the water purification equipment, reverse osmosis device all the import and export of valves.

长期停用保护适用于停运15d以上的系统,这时必须用保护液(杀菌剂)充入净水设备反渗透装置进行保护。常用杀菌剂配方(复合膜)为甲醛10(质量分数)、异噻唑啉酮20mg/L、亚硫酸氢钠1(质量分数)。

The long-term shutdown protection applies to stop the system above 15d, then we must use protective liquid (disinfectant) into the water purification equipment, reverse osmosis equipment protection. Common Fungicides formula (film) formaldehyde 10 (mass fraction), isothiazolone 20mg/L, sodium bisulfite 1 (mass fraction).
