6.2.2.1. Prepare suitable cleaning solution with correct pH value per section 6.2.5.
Be sure that all chemicals in the solution have been fully dissolved and evenly mixed to be transparent and clear solution before it is filled into the film.
准备适当的清洗液，准确的PH值依照6.2.5节.在加入清洗液之前，确认所有的化学品已完全溶解混合均匀。
6.2.2.2. The solution is filled into the film tube by low pressure and flow of pump.
The pressure shall be low enough that no osmosis happens. The cleaning solution shall be first discharged and then circulated.
用泵的低压流量打入膜管，低压控制在无渗透液产生.清洗液先排放后循环。
6.2.2.3. The acid will be consumed when it dissolves the inorganic sediment and its
pH value shall rise by 0.5 unit. Add acid at that time until the pH value drops by 0.5..

6.2.3. Contamination of Reverse Osmosis Film Module
反渗透膜污染
6.2.3.1. After a period of normal operation， the complex polyamide reverse
osmosis film module could be contaminated by some suspends or matters difficult to dissolve in water supply such as calcium carbonate， calcium sulfate， metal oxide， silicon sediment， organic or inorganic sediments. 运行一段时期后，复合反渗透膜会受到水中悬浮物和难溶物的污染，如碳酸钙，硫酸钙，金属氧化物，硅沉积，无机物和有机物沉积物。
The character of pollutant and contaminating speed depends on the quality of the water supply. The contamination can happen quickly and needs to be monitored because the film module can be damaged in a short period of time. 污染物的性质及污染速度与给水有关.污染发生很快需监控，因为污染会在很短的一段时间损坏膜。
6.2.4. Elimination of Pollutant
污染物的去除
The pollutant can be eliminated either chemically or physically. Therefore， the RO system shall be cleaned after daily operation in physical way of low pressure
operation for 15 minutes in order to get rid of the surface dirt. But chemical cleaning must be done if any of the following happens:
污染物能够用化学或物理的方法去除.因此，RO系统每天运行后可以用物理冲洗的方法去除膜表面的沉积物。
6.2.4.1. The flow reduces by 10% of the normal flow even in normal pressure and
temperature.
在正常的压力和温度下流量降低正常值的10%。
6.2.4.2. The conductivity of the produced water has been more than double
of the original conductivity in condition that the working pressure and inlet conductivity remains the same.
在原水电导率和工作压力不变时，产品水电导率超过初期两倍时。
6.2.4.3. The difference of working pressure and the concentrated water has
been more than double of the original value. 工作压力和浓缩水超过初期两倍时。
