Tips for Cleaning a Reverse Osmosis Water Filter

Cleaning the RO water filter successfully

Reverse osmosis water filtration systems, also referred to as hyper filtration systems or RO systems are recognized to be the top water purification systems found. This is primarily owing to the wide array of contaminants of water that can be removed by the systems. Cleaning the RO water filter is considered to be vital for periodical maintenance for conferring the best ever results and avoiding serious damages

Here are some tips to clean the reverse osmosis water filter:

When you should clean the RO system

It is essential to note the values and closely monitor the RO system. Cleaning of the system is recommended highly in three specific instances. The first is when the normalized flux has been reduced, even by smaller amounts. Another instance is when normalizes salt content of filter is raised slightly and in case you notice a reduction in the rise in pressure in the pressure container. You should clean the RO system in every 3 to 12 months according to the fouling which the Reverse osmosis water filter is subjected to.

How to conduct the cleaning procedure

With the frequency of cleaning, the time needed in order to clean the RO filtration system range from 4 to 8 hours, depending on the amount of fouling that is present. It is essential that the cleaning procedure should begin with low flow circulation along with filtrated water for the removal of dirt and clogging. After this, you require introducing the cleaning solution as recommended by the manufacturer. The cleaning solution should be kept in the filtration process for a time duration of 60 minutes. If there is a change in PH above 0.5 pH units, you require adjusting the same to the targeted pH value prior to proceeding. The similar cleaning technique needs to be used in different subsequent stages. You can include an optional soak and recirculation, following the instruction of the manufacturer and ensuring that the proper pH and temperature can be maintained. It is also recommended to make application of low pressure and rising the filtered water for the removal of chemical residues from RO skid and cleaning skid.


A wide variety of tools is a prerequisite for the optimal cleaning results. Soft water or RO filtered water needs to be used for the dilution of cleaning systems and cleaning the systems. This is a prerequisite for top cleaning results and for the longevity of components present in RO water filter.

Other tools are inclusive of RO cleaning pump, RO cleaning tank along with the right cross flow velocity for scrubbing the membrane clean, an RO tank cooler or heater, RO tank mixer, RO cleaning cartridge filter, cleaning dirt that is displaced during cleaning

In addition to this, use of instrumentation monitoring pressure, flow, temperature, and tank of tank level is advisable.

Things you need to keep in mind while cleaning the reverse osmosis water filtration system

As there is involvement of dangerous chemicals and delicate parts in RO system, you need to take care of a wide number of precautions for avoiding the damage of water filter or for the creation of health hazards. First of all, it is crucial to follow the suggested dosage, chemical list, temperature, PH value and contact time guidelines. You also need to make sure for using the mildest possible chemicals as this will raise the longevity of components. You should ensure to not mix acids along with caustics and dispose of the cleaning chemicals in an adequate manner. You require rinsing the first cleaning solution in a meticulous manner prior to the introduction of the next solution.

Cleaning the RO water filter successfully is crucial. However, if you do not obtain optimal results, you should consult an expert or manufacturer for making cleaning sessions more effective.
