Several methods of industrial waste water nanofiltration membrane fouling of industrial wastewater of nanofiltration membrane is widely applied in various fields of water treatment process, in order to make the industrial waste water of nanofiltration membrane performance is more stable, prevent the scaling is one of the more effective method, the prevention of industrial wastewater nanofiltration membrane fouling have what kind of method?
1, do a good job of raw water pretreatment, special attention should be paid to pollution index of qualified, but also should undertake sterilization, prevent microbes breeding in the device.
2, in the reverse osmosis
equipment operation, to maintain the appropriate operating pressure, in general, increased pressure will make water rate increases, but too much will make the membrane compaction.
3, in reverse osmosis equipment operation, should maintain a turbulent state of the brine side, reduce the concentration polarization of membrane surface solution, avoid some undissolved salt precipitation on the membrane surface.
4, in the reverse osmosis device is offline, short-term should undertake dosing wash, should add formaldehyde protection for a long time.
5, when the reverse osmosis equipment water rate decreased significantly, showed that membrane fouling or pollution, should carry on the chemical cleaning.
6, design enough lateral velocity and strong water flow velocity.
7, the operation data standardization.
Prevention of membrane fouling, completes the membrane maintenance work is the most reliable protection, the performance of the membrane during the users in the use of industrial waste water nanofiltration membrane must thoroughly understand the operation method, to ensure that the industrial waste water nanofiltration membrane remain the state of work, and prolong its service life.
There is a strong need for more research on , in order to be able to provide strong and conclusive evidence of their pure water treatment plant effects. However, recent studies have provided valuable insights into how the intake of may result in improved water purification unit.
Guangzhou Aomi Water Purification System Manufacture Co., Ltd. will continue to bring our industry nuances of style and approaches to water treatment systems
which are consistent with our evolving aspirations.
In conjunction with retraining and upskilling efforts, Guangzhou Aomi Water Purification System Manufacture Co., Ltd.’s workers should focus on growing unique human skills that high-tech machines are unable to replicate, such as strategic and abstract thinking, complex communications, creativity and leadership competencies.
