SUEZ AD-365 reverse osmosis membrane is an advanced desalination membrane produced by SUEZ, which is specially designed for the efficient removal of salt and other impurities from seawater, enabling water to meet the various requirements of freshwater use. The use of advanced nanofiltration technology can provide high water quality and is suitable for large-scale desalination projects, especially those with high requirements for the quality and cost-effectiveness of produced water. Below, the blue film water treatment will introduce to you the conditions to be met by its inlet water.
Conditions to be met for water ingress:
1.Temperature: The inlet water temperature should be controlled within a certain range to meet the operating requirements of SUEZ AD-365 desalination membrane. Generally, the inlet water temperature should be between 4-45, and the optimal temperature is about 25. Temperatures that are too high or too low may affect the performance of the membrane or even cause damage to the membrane.
2.Flow rate: The inlet flow rate needs to be controlled within the appropriate range to ensure the normal operation of the SUEZ AD-365 desalination membrane. Too much or too little flow can adversely affect the performance of the membrane. Therefore, when designing an influent system, the appropriate flow rate needs to be determined based on the specifications of the membrane and the process requirements.
3.Water quality: The quality of the influent water has a significant impact on the performance of the SUEZ AD-365 desalination membrane. In order to ensure the stable operation of the membrane and prolong the service life of the membrane, the influent water should meet the following water quality requirements:
Suspended solids concentration: should be less than 20 mg l to prevent membrane clogging.
Turbidity: It should be less than 1NTU to ensure the filtration effect of the membrane.
Salinity: Seawater has a high salt content and requires proper pretreatment to reduce the salt concentration in the influent water.
Hardness: The hardness in the influent water should be controlled within a certain range to prevent calcification of the membrane.
Organic matter: The organic matter content in the influent water should be reduced as much as possible to prevent contamination of the membrane.
4.Water inlet mode: In order to ensure the uniform cleaning and effective filtration of SUEZ AD-365 desalination membrane, the water inlet mode should adopt a continuous flow mode. In addition, in order to prevent clogging and contamination of the membrane, it is necessary to clean and maintain the membrane regularly.
5.Pretreatment: In order to ensure the stable operation of the membrane and prolong the service life of the membrane, the feed water needs to be pretreated. The pretreatment process includes steps such as sanding, sterilization, coagulation, flocculation, and sedimentation to remove impurities such as suspended solids, microorganisms, and organic matter in the water.
6.Add chemicals: In the process of water intake, certain chemicals can be added as needed, such as scale inhibitors, fungicides, etc., to prevent the pollution and corrosion of the membrane.
