The main components of manually controlled membrane testing equipment include feed pumps, membrane tanks, material tanks, and their control systems. The manually controlled membrane testing equipment 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 rectangle with a special flow channel design, 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. Microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes can be installed. Suitable for membrane testing research and filtration experiments with small amounts of feed liquid;

6. Adopting a 60L (coil) material tank, which can be connected to a temperature control circulation device for temperature control;

7. The equipment is equipped with an electronic digital pressure gauge with an accuracy of 0.4% FS, ensuring the accuracy of data and overcoming the defect of low accuracy of mechanical pressure gauges;

8. The membrane cell adopts a two parallel four string structure, where two sets of membrane cells are measured simultaneously or separately. Different membranes can be installed simultaneously, grouped or tested simultaneously to ensure consistency in feed flow rate and state.
