In the process of using reverse osmosis pure water equipment, the water production is decreasing rapidly. What's going on? What should we do in this situation? In this situation, it is necessary to first identify the cause and take remedial measures according to the situation.

Jingde Rui has listed relevant solutions, hoping to be helpful to everyone.

1、 Analysis of the reasons for the decrease in water production of reverse osmosis pure water equipment

1. Compaction of membrane components;

2. Reduce the number of membrane components;

3. The working temperature decreases;

4. The pressure difference increases during the operation of the reverse osmosis equipment;

5. Metal oxides and dirt adhere to the surface of the membrane;

6. Low voltage operation;

7. Oil mixing;

8. Run at a high recovery rate.

2、 Solution to the decrease in water production of reverse osmosis pure water equipment

When operating under conditions where the pressure is higher than the reference pressure, compact the membrane components and choose to replace them;

2. Operate normally according to the designed number of membrane components;

3. Operate at the design temperature of 25 ℃;

4. Improve the operation and management of water treatment equipment, improve reverse osmosis water quality, and clean membrane components.

5. Daily low-pressure flushing;

6. Conduct debugging and operation according to the design reference pressure standard;

7. Note that oil cannot enter the water supply system to replace membrane components;

When the recovery rate exceeds 75%, the amount of concentrated water decreases, and the concentration ratio of water in the membrane components will increase, leading to a serious decrease in feed water quality. As the osmotic pressure of the feedwater increases, the volume of permeated water decreases. In severe cases, salt deposits will settle on the surface of the membrane.
