On a regular basis, it is very important to sanitize the RO systems to keep it from becoming infected with a wide range of bacteria and other water-borne diseases.
Based on the universal health rule, drinking water from a filter that has not been disinfected causes over ten times the number of diseases as drinking water from a conventional faucet. Keeping your reverse osmosis system clean is very important so that you and your family don't get sick from bacteria in the RO system.
According to the manufacturer's recommendations, you should sterilize your reverse osmosis system every six months or so. Sani Systems for Reverse Osmosis Units is the only EPA and NSF approved reverse osmosis sanitizer that has been shown to eliminate 99.99 percent of potentially hazardous germs.
When it comes to drinking water in the house, a Reverse Osmosis Systems provide clean, filtered water. However, the reverse osmosis systems' maintenance is very crucial.
We've put up a short guide that will walk you through how to sanitize the RO system as well as give clear and concise answers to the most frequently asked questions on sanitizing RO systems..
How To Sanitize RO System
To sanitize your RO system, you need to get these four items ready:
-
Reverse Osmosis Sanitizer
-
A good chemical cleaner
-
A pair of gloves
-
Eye protection
Now that these items are ready, it's time to go through the step-by-step process of how to sanitize your RO system the proper way.
NOTE: Hand-washing is highly recommended. Since the reverse osmosis system generates such pure water, you want to avoid contaminating any portion of your system. Finally, make sure the environment is clean and dust-free, and then think about wearing gloves that are clean.
Step 1: Turn Off, Disconnect And Drain The Tank
Under this step, we’re going to do three important things.
1. The Water Supply Pipe To Your Ro Unit Should Be Turned Off.
In order to avoid water flowing out into your floor, be certain that there is no water running to the reverse osmosis system before turning it on. This can be achieved by turning off the water supply line of the RO.
2. Disconnect Any Lines That Are Connected To The Refrigerator.
If you are using reverse osmosis water in your refrigerator to make incredibly clear ice, be sure that it is turned off before you begin the process.
3. Drain The Tank By Opening The Faucet On The System.
You want to make certain that you completely drain the system of water. The action of turning on the faucet will also depressurize the storage tank. Leave the faucet open until all of the water has been drained, and then close it.
Step 2: Remove The Pre-Filters, Reconnect The Filter, And Apply The Sanitizing Solution.
In this step, we’re going to carry out three operations that involve the reverse osmosis filters. So be very careful here with the filter. In general, you can find your ideal Reverse Osmosis Replacement Filters here.
1. Remove All Pre-Filters As Well As The Membrane From The System.
Remove the filters from all of the filter housings by opening them all up. Except for the postfilter, there should be no filters or membranes inline with your system throughout the sanitization process.
If you are swapping them for new ones, the old filters should be thrown away at this stage.
2. Reattach The Filter Housings To The Rest Of The System.
With the exception of the pre-filter housing, all of the housings on the system should be replaced.
3. Fill The Pre-Filter With The Sanitizing Solution.
We suggest that you use the Sani-System sanitization solution, which has been approved by the National Sanitation Foundation. It is the only RO sanitization solution recognized by the Environmental Protection Agency, and it requires no measurement or mixing.
It does not include any chlorine and will effectively destroy any bacteria that may be forming in your aquarium. Reconnect the pre-filter housing to the rest of the system.
Step 3: Turn On The Water Supply, Wait A Few Minutes, And Then Flush.
At this stage, we also need to take a few actions to perfect the reverse osmosis system sanitation process.
1. Turn On The Water Supply Again.
Allow for the filling of the storage tank with water. Activate the RO faucet until water begins to flow out, indicating that the tank has been completely filled. Close the water supply valve.
2. Allow The Solution To Settle For A While.
This may vary depending on the type of sanitization solution you are employing. It is necessary to wait for at least one minute if you are using the Sani-System.
3.Completely Flush The Entire System.
Reverse osmosis systems must be allowed to flush themselves by opening the faucet. Wait for approximately five minutes. Pour more water into the tank and flush it once more to ensure that all traces of the disinfectant solution have been flushed out of the tank for the second time.
Step 4. Disconnect All Water Supplies, Replace Filters, And Reconnect.
This is the final step to sanitizing your RO system in order to prevent bacteria in your RO system.
1. Drain the system by disconnecting the water supply. 2.
To begin, turn off the water supply and turn on the faucet. Wait until all of the water has been drained from the system and the tank has completely depressurized before continuing.
2. Replace all of your RO system's filters and membranes.
This is a perfect time to change your filters since combining system maintenance with filter replacements guarantees that your system is cleaned on a regular basis and that your filters are updated on schedule. Get Reverse Osmosis Replacement Filters here.
3. The water supply should be reconnected.
If you had unplugged any ice-maker or refrigerator connections previously, you should reconnect them now. After that, you may use your reverse osmosis system again as long as you let the water in the storage tank fill up completely first.
Why Maintain Your Reverse Osmosis System?
Maintaining your reverse osmosis system is crucial to ensuring that your system continues to function properly and that your supply of pure, clean water continues to flow freely. Maintaining your reverse osmosis system on a regular basis will help you avoid costly and unnecessary costs, keep your water pure, and keep your system running for a long time.
It is important to keep up with reverse osmosis system maintenance in order to keep it running properly and efficiently. Throughout its operation, the system's many filters experience regular wear and tear as they filter out hazardous and undesired contaminants. Replacement of the filters on a regular basis can help your RO system last for a long time. This could be up to 10-15 years!
Additionally, replacing your filters on a regular basis helps to keep costs down. If they are not maintained, the cost of replacing the filters and membranes might become prohibitively high.
The pre-filters in your reverse osmosis system safeguard the sensitive membranes by removing debris and chlorine from the water passing through them. Any quantity of chlorine that makes its way into your membrane will cause it to malfunction.
Do I Need To Sanitize My Ro System?
Yes, it is recommended that you do a system sanitization and recharge at least once a year. A specialist who works with water treatment might be able to help you with this kind of maintenance. You can also check the owner's manual for your RO system for more information. You can also check the owner's manual for your RO system for more information.
It's a good idea to fully sterilize your Reverse Osmosis System when you replace the reverse osmosis water filters, which should be done at least once every 12 months according to the manufacturer.
Most manufacturers say that you should clean your reverse osmosis system once a year, and this is usually true.
If you have trouble keeping track of time, I recommend noting a year from now on your calendar and making a note to clear up your system before that date. When you change your sediment and carbon filters, you could also choose to clean your system. These filters usually last for 12 months to a year.
Can Bacteria Grow In Ro Water?
Yes, bacteria can grow in reverse osmosis water because there are no dissolved solids in it, so they can spread. From what I've discovered, bacteria can grow in reverse osmosis water just as easily as they can in conventional tap water.
Because your reverse osmosis drinking water system is generally an enclosed system that does not let air into it, and because of that, your water may have been exposed to oxygen prior to reaching your reverse osmosis system, bacteria may be present that can continue to develop inside your system.

In the case of carbon pre-filters and post-filters, they are excellent environments for bacteria to colonize and grow. The bacteria will nestle into the holes of the carbon particles and subsequently proliferate, resulting in the formation of a colony of the bacteria in the system.
A wrinkle or crevice could also be found in any connection between a tube and fitting, or from one part of the reverse osmosis system to another. This means that bacteria could get into the system through these places.
How Often Should I Sanitize My Reverse Osmosis System?
Once a year, you should sanitize your reverse osmosis system to keep it running smoothly. There is a good chance this will kill any hazardous bacteria that may be developing in your water storage tank or on the filter components.
The RO system should be sanitized whenever you do any work on it, like changing the filter or putting in new hoses. Doing this will prevent bacteria from growing in the system.
The following advantages can be obtained from the sanitation of a RO system:
-
Biofilm, organic materials, and other substances are removed;
-
This reduces the chances of performance issues;
-
This allows the system to provide better quality water.
In the RO system, a lot of things can cause it to get clogged up. These things include changes in the water's composition and biological contamination, the build-up of debris and other substances that precipitate, and not flushing the system after it shuts down.
It's still a good idea to sanitize the RO tank at least once a year when you change the 12-monthly filter cartridges, even if it doesn't always need to be done.
If your RO system is intricate, and you don't have a lot of plumbing skills, you may need to hire a plumber to clean the entire system for you.
Does Bleach Hurt Ro Membrane?
When it comes to sanitizing your reverse osmosis drinking water system, I recommend utilizing an EPA and NSF approved non-bleach sanitizer or around 3 tablespoons of unscented household bleach to get the job done.
This is really crucial! Any reverse osmosis drinking water system must have the membrane removed before it can be sanitized, and this is especially true for commercial systems.
Yes, it does. When a reverse osmosis membrane is exposed to chlorine bleach or any other corrosive chemical, it may cause holes to form in the semi-permeable membrane material. This could cause the membrane to break down.
If holes form in the membrane, the toxins in the untreated water can find their way through the perforations and into your drinking water, contaminating your water supply.
How Long Does It Take Bacteria To Grow In Ro Water?
According to the calculations, the total specific cell growth rate, which reflects the growth potential of the entire system, is 0.07-0.08 day(-1), implying that the system will double in 9.1–10.1 days.
They may be symptomatic of the possibility of bacterial growth in RO permeate water with low levels of readily assimilable organic carbon in comparison to those recommended for biostability. According to the manufacturer, RO permeate water does not appear to be biologically stable water.
As a result, efforts to keep bacteria from growing in RO permeate water and in the distribution system must take into account how the water will be cleaned after it has been disinfected. Source: PubMed
Final Thoughts
In summary, sterilizing a reverse osmosis system is a very simple do-it-yourself project. However, depending on the quality of your water, this may be essential to guarantee that the drinking water filter's effectiveness is not jeopardized. Additionally, sanitization helps to avoid fouling and microbiological infestation. The ideal time to clean is when you replace the various filter pieces.
You should first wash your hands before starting, and then just follow the directions in your user handbook. Consult our guidelines above for reference. You may also clean the storage tank.
