Ceramic membrane filtration system (BNCM19-6-M) is an automatic production equipment, which is composed of six 19 core membrane modules. Each membrane module contains 19 membrane elements, which can be used for the production of concentration, separation, purification, clarification and other processes of feed solution. This set of equipment can be replaced with 5nm-1500nm Ceramic membrane elements, membrane element model: JDM30-19-4-1200. The main components of the system include feed pump, circulating pump, Ceramic membrane components, backwash system, control cabinet and system pipeline, circulating tank, cleaning tank, etc.

1. Host

The system adopts an integrated structural design and a pry mounted structure, with no sanitary dead corners on the surface of the equipment that meets GMP requirements;

The system is equipped with a security filter to prevent damage to the membrane core caused by the mixing of foreign materials;

The system is equipped with pressure, temperature and other instruments, which can achieve online monitoring;

The system is equipped with instruments such as flow, pressure, liquid level, temperature, etc., which can achieve online monitoring of various parameters, system protection, and alarm;

The system is equipped with a CIP online cleaning system, which can achieve one click cleaning of the system. The batch cleaning time of the system does not exceed 2 hours (depending on the specific project situation);

The main equipment, except for the sealing parts, is made of SUS304 stainless steel material;

Adopting automatic argon filling protection, single sided welding, double sided forming, all welds polished, smooth and flat, the internal and external surfaces of the pipeline are of excellent quality, clean and hygienic, safe and reliable.

2. Membrane components, membrane components

The membrane filtration system adopts Bona high-quality Ceramic membrane element with strong anti pollution ability, stable flux and easy cleaning.

3. Pump body

The feed pump adopts a domestically produced high-quality multi-stage vertical centrifugal pump, which uses a frequency converter to start control and provide pressure and external circulation flow for the membrane components. The pump provides high pressure, small volume, and reliable and stable performance.

The circulation pump adopts domestic high-quality horizontal stainless steel centrifugal pump, and the frequency converter startup control provides pressure and internal circulation flow rate (membrane surface flow rate) for the membrane components. It adopts a double end mechanical seal without oil seal, which will not cause material pollution due to seal wear. This pump provides high flow rate, stable and reliable operation, and strong corrosion resistance.

4. Tank body

The system needs to be equipped with one 600L cleaning solution tank, with reserved pipelines, valves, reserved holes, etc. designed according to production and automation control needs.

5. Seals

Based on years of relevant engineering experience and pilot tests conducted by Bona Company, sanitary grade VMQ materials are used for sealing between system pipelines and valves, and PTFE+EPDM is used for sealing membrane components, which are acid and alkali resistant and can ensure the sealing stability and safety of the system.

6. Safety devices

The system monitors all safety related parameters in real-time operation, and takes corresponding actions or automatically shuts down protection and beeps alarms according to different situations. The alarm information accurately records the fault location and cause, and the alarm records can be traced. The system is equipped with an emergency stop button, which stops the system immediately when pressed, and enters standby mode when reset.

7. Self-control process

The system displays real-time working pressure, flow rate, temperature, liquid level, pump operation status, valve switch status, operation mode, operation status, alarm information, etc; The circulation pump and feed pump are controlled by a frequency converter, and the operating frequency can be set and displayed to control the flow rate and membrane pressure difference of the circulating materials in the system, ensuring a membrane surface flow rate of 3-5 m/s required for membrane filtration. The equipment operation history can be traced and the data should be stored for at least 24 months.

8. Equipment cleaning

During the production process, the membrane itself will generate pollution, thereby reducing membrane flux. To restore membrane flux, it is necessary to clean the membrane. The system is equipped with a cleaning tank, and the cleaning process takes 1-2 hours depending on the membrane contamination and utility conditions.

One circulating pump, one feeding pump, one slag discharge pump, six sets of membrane components, 114 membrane components, one cleaning tank, two material tanks, one thick liquid flow meter, one night cleaning flow meter, three pressure sensors, one temperature sensor, three liquid level sensors, a unified set of recoil system, one control system, two security filters, and several equipment racks, valves, connecting clamps and their connections.

Advantages of Ceramic membrane filtration system:

The membrane surface is not prone to concentration polarization and membrane surface pollution, and the attenuation of membrane transmission rate is slow;

Using pressure as the driving force for membrane separation, the separation device is simple, easy to operate, and easy to achieve automation;

The separation process has no phase change and significant energy saving, and can be achieved within the accuracy range of 5nm~1000nm (precision outside the range needs to be customized);

Resistant to strong acids and alkalis, the cleaning process is simple and convenient, and can be subjected to high intensity frequent backwash cleaning and high concentration, long-term chemical cleaning;

Widely applicable, widely used in fields such as chemical, food, medicine, environmental protection, biotechnology, energy engineering, etc;
