The main components of the automatic control diaphragm testing system include the feed pump, membrane tank, material tank, and its control system. The automatic control membrane testing system produced by Shandong Bona Biotechnology Group Co., Ltd. can be replaced with microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, and seawater/brackish water desalination membranes, suitable for various membrane testing and research, filtration and separation of small amounts of materials, teaching demonstrations, and experimental research. Widely used in fields such as biology, pharmaceuticals, food, chemicals, environmental protection, etc., for process experiments such as concentration, separation, purification, clarification, and sterilization of feed liquids. Circular or square membrane cells of different sizes can be customized according to experimental requirements.

1. The internal and external surface quality of the pipeline is excellent, and the entire set of equipment materials come into contact with the pipeline without any welding points, ensuring the equipment's pressure resistance and corrosion resistance performance. Easy to operate, clean and hygienic, safe and reliable;

2. The pump adopts a pressure sensing system and a frequency conversion control system, which can adjust the pressure and flow rate through frequency conversion. It can set the ideal pressure and achieve automatic overpressure protection, making the use process very safe;

3. The membrane tank is designed as a square, with a special flow channel design and a water distributor, which can ensure stable and consistent pressure and flow rate at each point of the membrane;

4. Design according to fluid dynamics to ensure tangential flow and turbulence in the membrane pool, and ensure the reliability and stability of test data;

5. Can install microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes;

6. Adopting a 20L material tank, it can be connected to a high and low temperature circulation device for temperature control;

7. The equipment is equipped with an electronic digital pressure gauge with an accuracy of 0.4% FS, which can accurately record testing high and low pressure data, ensuring data accuracy and overcoming the defect of low accuracy of mechanical pressure gauges. The pressure gauge can be directly connected to a computer for data recording;

8. The membrane cell adopts a two string and two membrane cell structure, which can simultaneously install different membranes for simultaneous testing to ensure consistency in feed flow rate and state;

9. Online testing of inlet temperature, inlet pressure, concentrated water pressure, inlet conductivity, produced water conductivity, produced water flow rate, concentrated water flow rate, water tank pH, etc. The required data for the measurement project should be transmitted to the supporting computer system, and the conversion should be completed by the built-in calculation software in the computer; It can achieve unmanned monitoring and automatic operation.
