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，雷火平台（中国）股份有限公司官网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，定期对雷火平台（中国）股份有限公司官网膜元件进行清洗，提高其运行稳定性.并有效的延长雷火平台（中国）股份有限公司官网膜的使用寿命，从而降低运行成本，接下来雷火平台（中国）股份有限公司官网一起了解一下雷火平台（中国）股份有限公司官网膜污染的情况有哪几种：

1、 胶体污堵

 辨别是否为胶体污染，需要测定原水SDI值,在膜分离的过程中，金属离子的浓缩及溶液PH值得变化，都有可能是金属氢氧化物沉积，最初的表现是脱盐率轻微降低，并逐渐增大，最后便是压降升高，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第一段，通常的故障原因是：进水中含铁和铝，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的腐蚀产物。

3、结垢

   结垢是微溶或难溶盐类沉积在膜的表面，一般出现在预处理较差且回收率较高的系统中，常常发生在RO系统的最后一段，然后逐渐向前一段扩散。辨别方法：查看系统的浓水侧是否有结垢，取出最后一支膜元件称重，存在严重结垢的膜元件一般比较重，分析原水水质数据。

4、胶体污堵

   在膜分离的过程中，金属离子的浓缩及溶液PH值得变化，都有可能是金属氢氧化物沉积，最初的表现是脱盐率轻微降低，并逐渐增大，最后便是压降升高，产水量变低。

3、颗粒污堵

   颗粒污堵的情况多为精密过滤器出现问题，从而导致过滤不彻底，引起膜污染。

   以上便是关于怎么查看中小型不锈钢RO纯水设备雷火平台（中国）股份有限公司官网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辨别污染状况，采取正确的解决措施，有效恢复雷火平台（中国）股份有限公司官网膜的性能，确保中小型不锈钢RO纯水设备产水合格。

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 about the reverse osmosis membrane pollution with what kind of things are:

1. Colloid fouling

In the process of membrane separation, the concentration of metal ions and the change of solution PH value may be the deposition of metal hydroxide. The initial performance is that the desalination rate slightly decreases and gradually increases, and finally the pressure drop increases and the water yield becomes lower.

2. Metal oxide fouling

Metal oxide fouling occurs mainly in the first stage, and the usual fault causes are: iron and aluminum in the water, H2S in the water, and air entering the water, resulting in corrosion products produced by sulfide salts, pipes, pressure vessels and other components.

3, scaling

Scaling is the deposition of micro-soluble or insoluble salts on the surface of the membrane. It usually occurs in the system with poor pretreatment and high recovery rate. It usually occurs in the last section of the RO system, and then gradually diffused in the previous section. Identification method: check whether there is scaling on the concentrated water side of the system, take out the last membrane element and weigh it. The membrane element with serious scaling is generally heavy, and analyze the raw water quality data.

4. Colloid fouling

In the process of membrane separation, the concentration of metal ions and the change of PH value of solution may be the deposition of metal hydroxide. The initial performance is that the desalination rate slightly decreases and gradually increases, and finally the pressure drop increases and the water yield decreases.

3. Particle fouling

Particle fouling is often caused by the problem of fine filter, which leads to incomplete filtration and membrane pollution.

The above is about how to view the small and medium-sized stainless steel RO pure water equipment reverse osmosis membrane pollution situation related answer, the user can through the actual situation of the above content to identify the pollution situation, take the correct solution measures, effectively restore the performance of reverse osmosis membrane, ensure the small and medium-sized stainless steel RO pure water equipment water production qualified.
