How do I know if my RO membrane needs replacing?
Most of the RO membrane manufacturer recommends that you need to change the membrane every one or two years but that is not the case. You can easily figure out the exact time of RO membrane replacement on your own. I will share with you simple step by step calculation in this section.
- Check the TDS of your RO feed or Inlet water(R1) & RO permeate(R2) water every month and note it down.
- Substract the RO permeate water from RO feed water. Note down it as R3
- Divide the R3 value by R1 value and multiplying it by 100. You get the rejection percentage(R) capacity of your RO membrane.
- If R value is greater than 90% then you don’t required to change the RO membrane. You only need to change the RO membrane when R value is less than 90%
Let’s take one example to understand it clearly.
RO feed water is 500 ppm & you get the permeate water with TDS of 20.
In this example,
- R1 = 500ppm & R2 = 20 ppm
- R1-R2= 500-20= 480 ppm(This is R3 value)
- R3/R1= 480/500*100= 96% (This is R value)
Here, R value is greater than 90% means your RO membrane is working fine and you don’t need membrane replacement.

When the market is filled with different filters to choose from, it can definitely be hard to find one that you like best and that works for your needs.
The Konvio Neer is the best RO membrane in India you can find, probably anywhere else. It is a perfect choice even for high TDS water up to 3000 ppm.
Frequently Asked Questions(FAQ’s)
What is RO GPD?
GPD stands for gallons per day. 1 gpd is equals to 3.79 liters per day.
What is the life of RO membrane?
Normally, the RO membrane lasts up to 2 years. It depends upon the TDS & water quality of inlet water.
Can We use RO reject water?
You can use RO reject water only in some of the activities like cleaning, flushing & gardening. RO reject water contains a huge amount of impurities & hardness so you need to check suitability & compatibility with the application where you want to use it.
