RO membrane plays a very important role in pure water equipment for tap water production. Without it, the equipment would not have a good water purification effect, so they all complement each other. How long does it usually need to be replaced after use?

The frequency of replacing RO membranes in pure water equipment for tap water production is around 2 years. RO reverse osmosis water purification equipment 1. It is a separate water supply, with purified water supplied for consumption and concentrated water used for cleaning; Ultrafiltration water purifiers are generally used for cleaning tap water; 2. When the water quality of tap water is relatively high, it can also be used as ultra pure water equipment for domestic water use.

Under normal conditions, it is sufficient to replace it once every 1 to 2 years, but it also depends on the condition of the water body. During the required application period, if the water body of the pure water equipment meets the regulations, it does not need to be replaced. If the water body decreases, it must be replaced immediately. There are also some key reasons, such as the uncertainty of the replacement time for the RO membrane's service life, which may be changed due to the quality of the RO reverse osmosis permeate water body. Generally speaking, the permeate water body meets the regulations, which means that the preparation treatment of the pure water equipment is stable, so it can achieve the required service life of the RO membrane. If the early preparation treatment has significant fluctuations, the service life of ROro reverse osmosis membranes will be shorter.

It is difficult to have a standardized answer to this question. In general, the RO membrane in ultra pure water purification equipment is replaced every 1-2 years. However, the detailed situation must also be determined based on the condition of the water producing body. Within the required application period, if the water producing body of the pure water equipment meets the regulations, it does not need to be replaced. If the water body decreases, it must be replaced immediately. The key reason is that the service life (replacement time) of the RO membrane is uncertain and may change due to the quality of the RO reverse osmosis permeate water body. Generally speaking, if the permeate water body meets the regulations, that is, the preparation treatment of the pure water equipment is stable, then the required service life of the RO membrane can be achieved. If the pre-treatment fluctuates greatly and the water seepage of the RO reverse osmosis device decreases, it will seriously endanger the characteristics and service life of the RO membrane, thereby endangering the final water production. At this moment, the RO membrane must be replaced immediately.

RO membrane components are key components of pure water equipment system software, which can soften the device to remove residues on the surface of RO membrane throughout the application process. However, they must be replaced after a period of application. The service life of RO membranes depends on many factors, such as organic chemical reliability, physical reliability, cleaning power, source water quality, preparation treatment, cleaning frequency, actual operation, and manipulation of water bodies. RO membranes can generally be used for 3-5 years under normal working conditions. However, analysis should be conducted based on detailed information. For example, if the quality of the source water is too low and there is a lot of residue, the killing power of the RO membrane will be higher, and the service life of the RO reverse osmosis membrane will be reduced. On the contrary, if the quality of the raw water is very good and the operator performs moderate maintenance on it every day, organic chemical cleaning is generally carried out every 6 months (cleaning must be done every quarter if it exceeds 2 years). It is not impossible to apply RO membrane for 6-8 years.
