As the water supply network ages, drinking water is prone to deterioration in ageing and rusted pipes. The emergence of home RO reverse osmosis membrane makes this problem solved, so how to choose a high-quality home RO reverse osmosis membrane?

1. Appearance

When choosing a Residential RO membrane you should first look at the membrane to see if it is intact and fresh to avoid external factors that may cause the RO membrane to be incomplete. In addition to the eye, you can also smell the smell, due to production and external environmental factors, deteriorating membranes will have a strange smell that can be smelled directly.


2. Desalination rate and salt permeation rate

Desalination rate refers to the percentage of soluble impurities removed from the feed water of the system by the RO membrane. Salt permeability refers to the percentage of soluble impurities in the feed water that pass through the membrane. The desalination rate of a domestic RO membrane element is determined when it is manufactured and shaped. The desalination rate depends on the density of the ultra-thin desalination layer on the surface of the membrane element, the denser the desalination layer the higher the desalination rate and the lower the water yield. Therefore, when choosing a home RO membrane, the desalination rate and salt permeation rate should be carefully examined.


3. Water yield and permeate flow rate

Water yield, also known as water flux, refers to the capacity of a household RO membrane, i.e. the amount of water per unit of time through the membrane, usually expressed in tonnes, hours or gallons. The permeate flow rate is also an important indicator of the amount of water produced by a domestic RO membrane. If the permeate flow rate of the home RO membrane is too high, it will lead to a faster flow of water perpendicular to the membrane surface and increase membrane contamination.


4. Recovery rate

Recovery rate refers to the percentage of the feed water in the membrane system that is converted into produced water or permeate. The recovery rate of a domestic RO membrane system is determined at the time of design and is based on the preset feed water quality. The higher the recovery rate, the longer the service life and vice versa.


When choosing a RO membrane for your home, you can choose a quality membrane by first looking at the shape and then measuring the performance to bring quality drinking water to yourself and your family. Reverse osmosis membranes are becoming more and more popular and loved by users. For more information about reverse osmosis membranes, please contact us!
