SUEZ AK-4040FM ultra-low pressure reverse osmosis membrane is a highly efficient water treatment membrane product that is able to operate at a lower pressure drop, which means energy savings and lower operating costs in the water treatment process. The membrane adopts advanced materials and design, has strong anti-fouling ability, and can maintain stable performance under complex working conditions. Below, the blue film water treatment will introduce to you its troubleshooting methods.
How to troubleshoot failures
1. Check the appearance of the membrane element.
First, inspect the appearance of the SUEZ AK-4040FM reverse osmosis membrane element and observe for visible breakage, deformation, or dirt. If the appearance of the membrane element is found to be abnormal, it needs to be replaced or cleaned in time.
2. Check the pressure drop of the membrane.
1.Close all valves of the membrane system to ensure that the system is closed.
2.Remove the membrane element, inspect the membrane surface for dirt and particles, and clean it with clean water if necessary.
3.A pressure gauge is used to measure the pressure difference between the inlet and outlet of the membrane element and record the data.
4.Compare the actual pressure drop with the standard pressure drop (the standard pressure drop is generally 0.).1-0.2MPa) if the actual pressure drop exceeds 1 of the standard pressure drop5 times, indicating that the membrane element has a clogging or fouling problem and needs to be cleaned or replaced.
3. Check the membrane desalination rate.
1.Influent, concentrated and fresh water samples of SUEZ AK-4040FM reverse osmosis membrane were collected and the conductivity, turbidity and other indicators were analyzed.
2.The desalination rate of the membrane is calculated by the formula: (Conductivity of inlet water - Conductivity of concentrated water) Conductivity of inlet water 100%. Under normal circumstances, the desalination rate should be above 90%.
3.If the desalination rate is less than 90%, it is possible that the membrane element is damaged or clogged with dirt and needs to be cleaned or replaced.
4. Check the installation and sealing of the membrane element.
1.Check that the membrane element is installed correctly and ensure that the seal between the membrane element and the membrane housing is good.
2.Check the membrane element connection tubing for damage, leakage or looseness.
3.Check whether the inlet and outlet valves of the membrane system are opened normally and there is no abnormal resistance.
5. Check the pretreatment system.
1.Check the operating status of the equipment of the pretreatment system, including pumps, filters, softeners, etc.
2.Collect inlet and effluent samples from the pretreatment system, and analyze the turbidity, SDI (sludge density index) and other indicators.
3.If there is an abnormality in the pretreatment system, it may affect the operation of the reverse osmosis membrane and the pretreatment system needs to be cleaned, maintained, or replaced.
6. Check the operating parameters of the membrane system.
1.Check the operating parameters of the membrane system, such as inlet pressure, temperature, pH value, etc., to ensure that it is within the normal range.
2.Adjust the operating parameters of the membrane system, such as ** rate, flow rate, etc., to achieve the best working conditions.
