Reverse Osmosis Membrane Cleaning
Even the best reverse osmosis system has to be well maintained to function properly. Only when a system is in good condition can it process water efficiently and remove its contaminants. One essential maintenance step is cleaning a system’s ro membrane, which is a reasonable alternative to cost-intensive replacements.
Membrane cleaning requires knowledge of when and how you have to clean and what chemicals you have to use. The right cleaner depends on the type of fouling/scaling the membrane has been exposed to.
In this blog post we are going to shed some light on those aspects and provide step-by-step instructions on how to clean your ro membrane at home.
When to Clean
Since it’s difficult to clean overly fouled reverse osmosis membranes and to prevent irreversible damage, it is crucial to stay on a strict schedule and clean them at an early stage of fouling.
The easiest way to find out when to clean is by monitoring water pressure before and after the system. If the differential pressure increases by more than 10%, it’s time to get active. The need for higher feed pressure to maintain water flow and decrease of flux are also clear indicators that your membrane needs to be looked after.
Of course cleaning frequency varies between different models from different manufacturers and also depends on the level of water contamination these are subjected to, but on average every ro membrane should be cleaned once about every 3 to 12 months. It is also helpful to take a look at the instructions provided or to get in touch with the manufacturer for further information.
How to Clean
The following instructions created by best-ro-system.com lead you through the process of cleaning an ro membrane. Please be aware that the necessary steps to clean a membrane without causing any damage to the system might vary from one manufacturer to another. This is especially the case for countertop systems.
By the way, we also have instructions on how to clean and sanitize an entire reverse osmosis system.
Time to get Started
You now have all the necessary information you need to clean the membrane of your reverse osmosis water filter system. You should be able to figure out how and when to clean and what chemicals to use in which sequence.
Remember: It is essential to follow the manufacturer’s specifications precisely to not cause any damage to your system. If you are unsure about your next step, seek professional assistance to avoid mistakes.
