Problems with reverse osmosis membrane equipment during use:

Compared with other desalination devices, such as evaporators, electrodialysis, and beds, reverse osmosis membrane equipment has unique characteristics and advantages, and the work of reverse osmosis localization has been paid more and more attention. With the increasing use of reverse osmosis technology, the problems have become more and more serious.

The above problems are mainly caused by the following reasons:

1.A full set of imported equipment due to the difference in raw water quality, lack of technical demonstration and process modification, copying and copying, is not suitable for China's actual situation. Therefore, the reverse osmosis water must be pretreated according to the difference of raw water quality to meet the requirements of the equipment for the influent water quality.

2.Some enterprises with poor technical ability do not understand the rational selection of the membrane components of the reverse osmosis device and the reasonable arrangement of the membrane components, which cause some membrane components to operate under abnormal conditions.

3.domestic film quality is not off. The quality of the film directly affects the removal rate of salt and other impurities. The Filmtec composite film produced by Dow Chemical Company of the United States can stabilize the rejection rate above 90.

4.operation management is not strict. When the system is running, the pressure should be within the range of the working pressure of the membrane to prevent super-strength, overload operation, causing gas-induced damage to the membrane, resulting in leakage. When the reverse osmosis system runs for a period of time, when the water production decreases sharply, the water quality deteriorates or the pressure difference increases, the membrane needs to be cleaned. At this time, the machine should be converted into a cleaning state, so that the system can be cleaned by itself, and the membrane can be recovered. The function.

Membrane is the key in reverse osmosis membrane equipment, and reverse osmosis technology has been widely used due to its special advantages. The cleaning problem of reverse osmosis water purification equipment may cause losses to many users with weak technical strength. Therefore, to manage the reverse osmosis membrane equipment, serious problems can be avoided.
