In recent years, people's requirements for water quality are getting higher and higher, in order to meet people's needs, reverse osmosis ultrapure water system was born, and to meet the public's recognition, in order to ensure the performance and stability of reverse osmosis membrane treatment, at the same time, it is necessary to do a good job of maintenance, equipment maintenance is in order to make the effluent water quality more stable, so we have sorted out the following maintenance methods, please come to understand.
1. Avoid frequent power on/off.
When the equipment is in normal operation, it is necessary to contact the water source first, and the pipeline of the equipment is inspected to see if there is water leakage, and the power supply is connected after the inspection is normal. After deactivation, turn off the power before disconnecting the water source. During the operation of the reverse osmosis equipment, it is necessary to avoid frequent disconnection of the water source in the power box as much as possible. The equipment adopts automatic control device, and frequent disconnection will affect the normal operation of the equipment and reduce the service life of the equipment.
2. Check the service life of the filter element.
In the process of long-term use, the reverse osmosis ultrapure water system needs to check the filter element regularly and replace the filter element regularly according to the regulations, so as to ensure the effluent quality of the equipment. If the quality of the pure water deteriorates after several months of continuous use, the pure water can be discharged according to the actual situation, and the equipment will automatically carry out the backwashing function.
Third, the water supply system needs to be independent.
The source water of tap water has an independent water supply system in the reverse osmosis water treatment equipment, which can ensure the stable operation of the water supply system, and at the same time reduce the huge pressure caused by the RO membrane on the water supply network of the whole plant. When the RO membrane takes water directly from the source water pipeline, a high and low pressure protection device should be set up to reduce the spillover caused by excessive pressure in the pipe network.
Fourth, do a good job of daily maintenance work, reverse osmosis ultrapure water system needs to do a good job of daily maintenance in the process of operation, so as to ensure the normal operation of the equipment. The water treatment equipment should be inspected regularly, and the reverse osmosis membrane should also be cleaned and discharged, so as to avoid the reverse osmosis membrane being blocked. In addition, the reverse osmosis membrane should be replaced in time to avoid affecting the effluent quality due to aging. 
The above are a few ways about the maintenance of reverse osmosis ultrapure water system, I hope it can help you.
