SUEZ AG-400,34LF is a high desalination rate, anti-fouling reverse osmosis membrane with high desalination rate, which can effectively remove divalent ions and organic matter in the water, ensuring that the effluent water quality meets high purity standards. The membrane adopts special antibacterial and anti-fouling technology, which effectively reduces the pollution and fouling on the membrane surface, prolongs the service life of the membrane, and reduces the operating cost. Below, the blue film water treatment will introduce to you the cause of its damage.
Some of the reasons why reverse osmosis membranes are damaged:
1.Physical damage: Improper handling during installation or cleaning may cause physical damage to SUEZ AG-400, 34LF reverse osmosis membrane elements, such as scratches, deformation or rupture. In addition, collisions or falls can occur during transport, resulting in damage to the membrane elements.
2.Chemical contamination: Chemicals in the feed water may react with the membrane material, resulting in degraded or damaged membrane performance. For example, chemicals such as residual chlorine, ozone, sulfate, etc. in the feed water may oxidize the membrane material and reduce the desalination performance of the membrane.
3.Biological contamination: Microorganisms in the influent water may grow and multiply on the membrane surface, forming a biofilm and reducing the flux of the membrane. In severe cases, microbial metabolites may corrode the membrane material, resulting in membrane damage.
4.Fouling: Divalent ions such as calcium and magnesium in the feed water may form insoluble carbonate scale on the surface of SUEZ AG-400,34LF reverse osmosis membranes, resulting in a decrease in membrane flux. Long-term accumulation, the scale layer may cause physical damage to the membrane.
5.Corrosion: Acidic or alkaline substances in the influent water may corrode the membrane material, resulting in degraded or damaged membrane performance. In particular, reverse osmosis membranes can tolerate a maximum pH of 11, beyond which damage can be caused to the membrane.
6.Oxidation: Reverse osmosis membranes that are exposed to air for long periods of time may be affected by oxidation, resulting in a decrease in the performance of the membrane.
7.Temperature and pressure: SUEZ AG-400, 34LF reverse osmosis membranes have their recommended operating temperature and pressure ranges. Outside of this range, damage to the membrane may occur.
8.Aging: Over time, reverse osmosis membranes may deteriorate, resulting in a decrease in membrane performance.
In order to prevent damage to the reverse osmosis membrane, the operation should be carried out in strict accordance with the operating procedures, and the membrane elements should be cleaned and replaced regularly to ensure that the influent water quality meets the requirements. At the same time, the operation status of the membrane should be checked regularly, and problems should be dealt with in time to ensure the long-term stable operation of the membrane.
