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, it is made from hydrophilic-modified PVDF raw materials, which provides built-in hydrophilic properties and eliminates the need for on-site hydrophilic treatment.
How should the PVDF membrane be stored if it is not used immediately?
If the membrane is not put into use immediately after installation, or if it needs to be parked, it must be kept immersed in water or kept wet at all times.
How does the diaphragm aeration system achieve self-cleaning of the membrane?
The system uses perforated aeration. The bubbles from aeration and the water flow work together to make the membrane vibrate fully, achieving self-cleaning.
What is the recommended intermittent operation mode for the self-priming pump?
The recommended mode is to have the self-priming pump suck for 10 to 12 minutes and then stop for 2 to 3 minutes to prevent clogging of the membrane pores.
When is the best time to put the PVDF membrane into operation for the first time?
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.
