China MBR Membrane Bioreactor Factory: High-Quality PVDF Suppliers for Advanced Wastewater Treatment Solutions
Hydrophilic and Moisturizing Membrane
The reinforced composite PVDF membrane is made from hydrophilic - modified PVDF raw materials, giving the membrane good hydrophilic properties. There is no need for on - site hydrophilic treatment. However, if the membrane is not put into use immediately after installation, or if it needs to be parked for a certain period during use, please ensure that the membrane is immersed in water or kept in a wet condition at all times.
Maintenance of Membrane Flux and Membrane Cleaning
The diaphragm aeration system is constructed using perforated aeration. The bubbles from aeration and the water flow work together to make the membrane vibrate fully, achieving self - cleaning of the membrane. An intermittent operation mode is used, where the self - priming pump sucks for 10 to 12 minutes and then stops for 2 to 3 minutes. This can effectively prevent the clogging of the membrane pores and ensure the long - term and stable operation of the membrane separation. When used for the first time, the microbiological culture in the biochemical pool achieves good activity, and the membrane is only put into operation when the viscosity is low.
Frequently Asked Questions
Does the reinforced composite PVDF membrane require on-site hydrophilic treatment?
No, there is no need for on-site hydrophilic treatment because the membrane is manufactured using hydrophilic-modified PVDF raw materials, which inherently provide excellent hydrophilic properties.
How should the PVDF membrane be stored if not used immediately?
If the membrane is not put into use immediately after installation, or if operations are paused, you must ensure the membrane remains fully immersed in water or kept in a wet condition at all times.
How does the self-cleaning mechanism of the membrane work?
The self-cleaning process is achieved by the diaphragm aeration system using perforated aeration. The combination of bubbles from aeration and the surrounding water flow causes the membrane to vibrate fully, cleaning its surface.
What is the recommended intermittent operation mode for the self-priming pump?
To effectively prevent membrane pore clogging and ensure stable long-term operation, the self-priming pump should suck for 10 to 12 minutes and then stop for 2 to 3 minutes intermittently.
When is the best time to start operating the membrane for the first time?
For the initial startup, the membrane should only be put into operation once the microbiological culture in the biochemical pool has achieved good activity and the overall viscosity of the pool is low.
