In winter, how will the properties of Мембрана зворотного осмосу film change?
With the coming of winter
The temperature is getting lower and lower, the water production of
Мембрана зворотного осмосу elements gradually decreases, but the desalting rate increases
What are the reasons for the change?
As the temperature of the water molecules decreases, the viscosity increases and the diffusivity decreases, resulting in lower water yield and at the same time, as the temperature decreases, the permeability of the solute decreases and the desalting rate increases
So, how should the Мембрани element be cured?Мембрани maintenance during system operation
1. The ambient temperature of the reverse osmosis system should be greater than 5°C
2. Increase the inlet water temperature or pressure
3. When the raw water temperature is below 10°C, it is recommended to use the raw water heater to heat the raw water to 20-25°0
Мембрани maintenance during system outage
1. Keep the temperature between 5-45°C
2. Low temperature is conducive to the preservation of membrane elements, but it should be prevented
System freezing
Unused Мембрани element curing
1. Dry film elements, the storage place must be cold and dry without direct sunlight, the ambient temperature should be lower than 45°C
2. Wet
Мембрани elements, it is necessary to pay attention to the storage environment temperature should be greater than 5 ° C, less than 45 ° C
3. If the
Мембрани element is frozen, in order to prevent the diaphragm scratch, the ice should be slowly melted at room temperature, and then pressurized after the complete absence of ice
Winter maintenance of reverse osmosis equipment
1. If installed indoors, ensure that the room temperature is not lower than 0 ° C, and heat the equipment if necessary
2. If the water inlet pipe is frozen and can not supply water or the water supply is small, do not forcibly start the reverse osmosis equipment to work, be sure to comply with the water requirements of the
Мембрана зворотного осмосу element, do not blindly pressurize
3. If it is installed outdoors, anti-freezing measures must be taken, and the water treatment equipment should be stopped when the temperature is lower than 0°C
