RO water purifier is the best choice if you want to have access to clean drinking water. But RO plant in itself requires the maintenance of various parts in the purifier system that helps in water purification. In all the devices fitted in RO, the Membrane is the most vital part of the water purifier.
What is Reverse Osmosis (RO) Membrane
RO membrane is the filter that does all the work. It is the primary system that works in the purification of the system. The sediment and carbon filters only work to prepare the water for the Reverse Osmosis membrane to be damaged. If the sediment and carbon filters are adequately maintained, only the membrane will be changed after purification around 4000 to 6000 litres of water.
But if we want to know how much the life of Membrane will last, then we need to know that life depends on various factors. The water's quality will determine whether the membrane will die early or longer. Apart from water quality input, water consumption and sediment and carbon filters' efficiency also play an essential role.
Generally, it has been observed that the Reverse Osmosis membrane lasts for about 2-3 years. However, there might be cases where membrane works for as long as five years. But remember, the water should not be challenging because it will force the Membrane to die early.
When to change RO Membrane
Now, if you are interested in checking whether to replace the RO membrane or not, then you should check the TDS of the water purified. If the TDS is going upward, then there is a high possibility that the Membrane needs to be changed.
Note that high TDS and hard water may compel you to change the membrane more frequently as compared to the standard time limit of 2-3 years.
