Effect of inlet water temperature on reverse osmosis membrane
Reverse osmosis system has strict requirements for water intake, if the water quality of the water is not qualified, it will cause pollution or damage to the reverse osmosis membrane, which will affect the water quality and normal work of the equipment.
What are the main effects of water inlet temperature on the performance of reverse osmosis membrane?
With the improvement of water requirements, the performance advantages of reverse osmosis membranes have also been recognized by more users. In the process of application, there will be many external factors that affect the performance and application of reverse osmosis membrane. With the increase of inlet temperature, the viscosity of water molecules decreases, and the movement speed increases, the water yield of reverse osmosis membrane will increase, and the desalting rate will decrease slightly. Under normal circumstances, the inlet temperature range of reverse osmosis membrane is 5 to 45 degrees, too low temperature will increase the risk of freezing the system, and the water production is too low, and the economic performance is relatively poor.
Therefore, it is not recommended to start the reverse osmosis system when the water temperature is below 5C. When it is higher than 45C, the water production of the reverse osmosis membrane is too large, and there is a risk of pollution.
Reverse osmosis membranes are widely used in municipal tap water treatment, single-stage seawater desalination and brackish water desalination. Chemical process and wastewater treatment. Adapted to the industry's widest operating and cleaning PH range, with extremely high compaction resistance, the highest temperature up to 45 degrees, extremely wear-resistant, in very harsh conditions of use, showing a longer and more stable trouse-free operation performance than other brands.
