Reverse osmosis membrane replacement cycle: influencing factors and quality selection

In the pursuit of quality of life today, clean water has become an indispensable part of our lives. And silently guard our drinking water safety, it is reverse osmosis membrane. So, how often do reverse osmosis membranes change? What factors affect its service life?

First of all, we have to understand that the replacement cycle of the reverse osmosis membrane is not static. It is affected by a variety of factors, including but not limited to inlet water quality, frequency of use, daily maintenance, membrane quality and pretreatment, pH, temperature, operating pressure, cleaning effect of membrane components, etc.

1.Inlet water quality: The quality of water directly affects the life of reverse osmosis membrane. If the water source contains a lot of impurities, high organic content and high hardness, it may lead to faster blockage or pollution of the element and shorten the replacement cycle. Therefore, for areas with poor inlet water quality, it is recommended to shorten the replacement cycle of the reverse osmosis membrane.

2.Frequency of use and water volume: In systems with high frequency of use and large amount of treatment water, the loss rate of the film may be accelerated, thereby shortening the service life of the membrane element. For home users, if the home population is large and the water consumption is large, then the loss rate of the reverse osmosis membrane will also accelerate accordingly. For industrial or commercial use, long time and high load operation is a serious challenge to reverse osmosis membranes.

3.Routine maintenance: Proper maintenance and regular cleaning can effectively extend the service life of reverse osmosis membrane. If abnormal conditions such as poor water quality, slow water production or water leakage are found, it is also necessary to replace the reverse osmosis membrane in time. Regular cleaning and maintenance of the reverse osmosis membrane can effectively remove dirt and impurities on the surface of the membrane and maintain its good filtration performance. At the same time, timely discovery and solution of water leakage, slow water production and other abnormal conditions can also effectively extend the service life of reverse osmosis membrane.
