The ninth-level membrane separation experimental machine can be equipped with microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane elements. It can perform single-stage filtration or multiple-stage continuous simultaneous filtration. 

2. At the same time, ceramic membrane filtration, ultrafiltration, nanofiltration membranes, and reverse osmosis membranes can be activated simultaneously to complete the clarification and filtration of the product solution, including staged ultrafiltration and nanofiltration for concentration and desalination, alcohol removal, reverse osmosis concentration, and the collection of the product solution in segments according to molecular weight. The entire process is continuous and controllable within the same time period. 

3. The concentrated liquid and the clear liquid are collected separately. 

4. The pressure sensing system is adopted, allowing for the setting of the maximum pressure. In case of overpressure, automatic protection is activated, ensuring a safe and reliable operation during use. 

5. Equipped with a variable frequency control system, it can adjust the pressure and flow rate by varying the frequency. 

6. The organic membrane elements are made with imported membrane components. The types of membrane components included are: one 200nm ceramic membrane element, one 500nm ceramic membrane element, one 100000D ultrafiltration membrane element, one 50000D ultrafiltration membrane element, one 10000D ultrafiltration membrane element, one 5000D ultrafiltration membrane element, one 800D nanofiltration membrane element, one 500D nanofiltration membrane element, one 200D nanofiltration membrane element, and one reverse osmosis membrane element. 

7. The organic membrane components comply with the FDA, 3-A, and USDA hygiene standards. 

8. By precisely configuring the pump's flow range according to the membrane surface flow rate of the sanitary membrane elements, it is possible to ensure that the experimental parameters selected for the equipment can be directly applied to industrial production. 

9. The power supply for the equipment is controlled by two switches. When the low-voltage power is in operation, it can fully ensure the safety of both the equipment and personnel. 

10. The membrane housing is designed based on fluid dynamics, ensuring the flow velocity on the membrane surface and guaranteeing the stability and reliability of the test data. 

11. Equipped with an automatic overpressure protection function, it will automatically shut down in case of overpressure, ensuring safety during use. 

12. Equipped with a temperature control module, it automatically shuts down when the temperature exceeds the limit, ensuring the stability of the materials during the experiment; it can set high and low temperature alarms and automatically start or stop; it can also be set with a timed start and stop function. 

13. It can be equipped with other types of organic microfiltration, ultrafiltration, nanofiltration and reverse osmosis membrane elements. 

14. All stainless steel welding is carried out using automatic argon gas protection, with single-sided welding and double-sided forming.
