2. Pump body
The feed pump uses a domestic high-quality horizontal stainless steel centrifugal pump (SS304), which uses frequency converter start control to provide pressure and external circulation flow to the membrane module. The pump provides high pressure, small volume, and reliable and stable performance.
The circulation pump uses a domestic high-quality horizontal SS304 stainless steel centrifugal pump. The frequency converter start control provides pressure and internal circulation flow (membrane surface flow rate) for the membrane module. It uses a double-end mechanical seal without an oil seal and will not cause material damage due to seal wear. pollute. The pump provides large flow, operation, stability and reliability, and strong corrosion resistance.
3. Tank body
The system is equipped with 1 cleaning tank, and is designed with reserved pipes, valves, reserved holes, etc. according to production and automation control requirements.
4. Membrane modules, membrane elements
It has been verified by small-scale and pilot-scale experiments that the membrane elements of this membrane filtration system adopt Bona's high-quality ceramic membrane elements, which have strong anti-pollution capabilities, stable flux, and are easy to clean. The equipment can be replaced with ceramic membrane elements ranging from 5nm to 1500nm.
5. Seals
Based on Bona's many years of relevant engineering experience and pilot experiments, PTEF is used as hard sealing material for system pipes, valves and other hard sealing materials, and PTFE+EPDM is used for membrane module seals, which are acid and alkali resistant, without any foreign matter falling off, and are not harmful to equipment and equipment. Any contamination brought by the product can ensure the sealing stability and safety of the system.
6. Safety device
The system monitors all safety-related parameters in real-time operation and has a self-protection function. It will respond accordingly or automatically shut down for protection according to different situations. It will buzz and alarm. The alarm information can accurately record the fault location and cause, and the alarm record can be traced. The system is equipped with an emergency stop button. When pressed, the system stops immediately. When reset, the device enters standby mode.
