There’s no denying that having a reverse osmosis filtration system at home (or even at your workplace) can greatly benefit everyone using it, since it’s one of the best and most recommended filtration systems for drinking water. However, like many other filtration systems, these also need to be cleaned in order to ensure that your water will continue to be purified.
In general, you’ll need to clean your RO system between 3 to 12 months, or when the system’s normalized flux has decreased, even by a small amount, or if the normalized salt content of your system has increased. Cleaning your RO system might take some time, which would usually take between four to eight hours, depending on how foul-smelling the system has become. Also remember to clean your system using RO-filtered water or soft water to further its longevity.
Normally, you start cleaning with a low-flow recirculation to remove clogs and dirt collected inside the system, then slowly apply the manufacturer-approved cleaning solution for an hour. Should there be any changes with the pH levels, this must be readjusted until the system achieves the recommended 0.5 pH.
Remember, on the other hand, that one slight mistake in cleaning can greatly affect your system’s filtration capabilities, thus you must always stick to the manual to avoid mistakes. Also exercise care in handling the parts, and keep in mind to use only the mildest chemicals when you clean your RO filtration system.
