High-Performance MBR Membrane Bioreactor for Wastewater Treatment from China Suppliers and Factory
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
Q: Does the reinforced composite PVDF membrane require on-site hydrophilic treatment?
No, it is made from hydrophilic-modified PVDF raw materials, which inherently provide excellent hydrophilic properties, eliminating the need for on-site hydrophilic treatment.
Q: How should the PVDF membrane be stored if not put into use immediately?
If the membrane is not used immediately after installation or needs to be paused during operation, it must be kept immersed in water or maintained in a wet condition at all times.
Q: How does the self-cleaning mechanism of the membrane work?
The diaphragm aeration system uses perforated aeration. The combination of bubbles from aeration and water flow causes the membrane to vibrate fully, achieving self-cleaning.
Q: What is the recommended operation cycle for the self-priming pump?
An intermittent operation mode is recommended: the self-priming pump should suck for 10 to 12 minutes and then stop for 2 to 3 minutes to prevent pore clogging.
Q: When is the best time to put the membrane into operation for the first time?
For initial use, the membrane should only be put into operation when the microbiological culture in the biochemical pool has achieved good activity and the viscosity is low.
