RO开云手机入口(China)官方网站膜为什么会损坏，如何防止RO开云手机入口(China)官方网站膜损坏
当使用中小型不锈钢RO纯水设备过程中已经发现产水情况发生了变化，比如水质或水量的降低，为了避免膜污染的情况经常的发生，我们要做的是定期更换滤芯 滤料，经常检测软化树脂是否正常运作，定期对开云手机入口(China)官方网站膜元件进行清洗，提高其运行稳定性.并有效的延长开云手机入口(China)官方网站膜的使用寿命，从而降低运行成本，接下来我们一起了解一下RO开云手机入口(China)官方网站膜污染的情况有哪几种：
1、颗粒污堵
颗粒污堵的情况多数情况为精密过滤器出现问题，从而导致过滤不彻底，引起膜污染。如果想要辨别是否为胶体污染，需要测定原水SDI值。因为在膜分离的过程中，金属离子的浓缩及溶液PH值的变化，都有可能是金属氢氧化物沉积。胶体污堵比较初的表现是脱盐率轻微降低，并且污堵会逐渐增大，比较后便是压降升高，产水量变低。
2、金属氧化物污堵
金属氧化物污堵主要发生在靠前段，通常的故障原因是：进水中含有铝和铁，导致进水中含H2S并有空气进入，产生硫化盐，管道、压力容器等部件产生腐蚀产物。
3、结垢
结垢是微溶或难溶盐类沉积在膜的表面，常常发生在RO系统的比较后一段，然后逐渐向前一段扩散，一般来说会出现在预处理较差且回收率较高的系统中，
解决方法：
分析原水水质数据，查看系统的浓水侧是否有结垢，由于存在严重结垢的膜元件一般比较重，这时可以取出比较后一支膜元件称重。
4、RO开云手机入口(China)官方网站膜消毒和保养不力导致微生物的污染
这是复合聚酰胺膜使用中普遍存在的问题,因为聚酰胺膜耐余氯性差,在使用中没有正确投加氯等消毒剂,加上用户对微生物的预防重视不够,容易导致微生物的污染。许多厂家生产的纯水微生物超标,就是消毒、保养不力造成的。
主要表现为:出厂时,RO设备没有采用消毒液保养;设备安装好后没有对整个管路和预处理设备消毒;间断运行不采取消毒和保养措施;没有定期对预处理设备和开云手机入口(China)官方网站设备消毒;保养液失效或浓度不够。
5、RO开云手机入口(China)官方网站膜余氯监测不力
如投加NaHSO3的泵失灵或药液失效,或活性炭饱和时因余氯损坏膜。
以上便是关于怎么查看RO纯水设备开云手机入口(China)官方网站膜的污染状况的相关解答，用户可通过实际情况对比上述内容分辨污染状况，采取正确的解决措施，有效恢复开云手机入口(China)官方网站膜的性能，确保中小型不锈钢RO纯水设备产水合格。

Why does RO reverse osmosis membrane damage and how to prevent RO reverse osmosis membrane damage
When using small and medium-sized stainless steel RO pure water equipment has been found in the process of water production situation has changed, such as water or water is reduced, in order to avoid the happening of membrane pollution often, we need to do is change regularly filter filter material, often test for a functioning softening resin, regularly to clean, reverse osmosis membrane element to improve the operation stability. And effectively extend the service life of reverse osmosis membrane, thus reduce the operation cost, then we know the RO reverse osmosis membrane pollution with what kind of things are:
1. Particle fouling
Particle fouling most of the situation for precision filter problems, resulting in incomplete filtration, resulting in membrane pollution. If you want to identify colloid contamination, you need to measure raw water SDI. Because in the process of membrane separation, the concentration of metal ions and the change of solution PH value may be metal hydroxide deposition. The initial appearance of colloidal fouling is that the desalination rate decreases slightly, and the fouling gradually increases, and finally the pressure drop increases and the water yield decreases.
2. Metal oxide fouling
Metal oxide fouling occurs mainly in the first stage, and the common fault causes are: the water contains aluminum and iron, which leads to the water containing H2S and air entering, producing sulfide salts, corrosion products of pipes, pressure vessels and other components.
3, scaling
Scaling is the deposition of micro-soluble or insoluble salts on the surface of the membrane, which usually occurs in the last section of the RO system and then gradually spreads to the next section. Generally speaking, scaling occurs in the system with poor pretreatment and high recovery rate.
Solution:
Analyze the raw water quality data and check whether there is scaling on the concentrated water side of the system. As the membrane elements with serious scaling are generally heavy, the last membrane element can be taken out and weighed.
4. Poor disinfection and maintenance of RO reverse osmosis membrane lead to microbial pollution
This is a common problem in the use of the composite polyamide film, because the polyamide film resistance to residual chlorine is poor, in the use of the correct addition of chlorine and other disinfectants, plus the user's attention to the prevention of microorganisms is not enough, easy to lead to microbial pollution. The pure water microorganism that a lot of manufacturer produce exceeds bid, it is disinfect, maintain weak cause.
The main performance is: when leaving the factory,RO equipment does not use disinfectant maintenance; The whole pipeline and pretreatment equipment are not sterilized after installation; Discontinue operation without taking disinfection and maintenance measures; No regular disinfection of pretreatment equipment and reverse osmosis equipment; Maintenance fluid failure or insufficient concentration.
5. Poor monitoring of residual chlorine in RO reverse osmosis membrane
Such as adding NaHSO3 pump failure or drug failure, or activated carbon saturation due to residual chlorine damage film.
The above is about how to view RO pure water equipment reverse osmosis membrane pollution status of the relevant answer, the user can through the actual situation of the above content to distinguish pollution status, take the correct solution measures, effectively restore the performance of reverse osmosis membrane, ensure small and medium-sized stainless steel RO pure water equipment water qualified.
