China MBR Membrane Bioreactor for Wastewater Treatment - Quality Suppliers and Factory-Direct 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
Q: Does the reinforced composite PVDF membrane require on-site hydrophilic treatment?
No, it is made from hydrophilic-modified PVDF raw materials, which gives the membrane inherent hydrophilic properties and eliminates the need for on-site hydrophilic treatment.
Q: How should the PVDF membrane be stored if it is not used immediately after installation?
If the membrane is not put into use immediately or needs to be parked for a certain period, it must be kept immersed in water or maintained in a wet condition at all times.
Q: How does the self-cleaning system of the membrane operate?
The system utilizes perforated aeration. The bubbles generated from aeration and the water flow work together to vibrate the membrane fully, which achieves effective self-cleaning.
Q: What is the recommended operation cycle for the self-priming pump?
It is recommended to run in an intermittent operation mode where the self-priming pump sucks for 10 to 12 minutes and then stops 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?
The membrane should only be put into operation when the microbiological culture in the biochemical pool achieves good activity and the viscosity of the water is low.
