What Is A Reverse Osmosis Filtering System?
Reverse osmosis filtration systems work by forcing water molecules through an extremely fine membrane using water pressure. As the water passes through the screen, harmful contaminants are left behind. The purified water is then collected from the clean side of the membrane while the contaminants are flushed out of a drain.
Conventional reverse osmosis systems are comprised of a chlorine/sediment pre-filter, the reverse osmosis membrane, a carbon-activated filter and a storage tank.
These filtration systems remove inorganic material found in water which makes them a great option for places with brackish drinking water. This is especially true since this water contains dissolved minerals that are hard to eliminate using other processes.
There are six possible stages in these systems (not including the storage tank). Not every reverse osmosis system has all six stages.
The Six Stages of Reverse Osmosis Systems
- 1st Stage– the sediment stage that eliminates rust, rough particles, and sand
- 2nd Stage– the carbon stage that gets rid of chlorine and other harmful chemicals that would damage the TFC reverse osmosis membrane. Multiple carbon cycles may be required depending on the quality of the carbon and the contact time.
- 3rd Stage– the reverse osmosis stage that eliminates any dissolved solids and essentially anything bigger than a water molecule. This is when most of the purification process happens.
- 4th Stage– the remineralization stage that remineralizes the water with magnesium and calcium to balance the acidity. Since water purified by reverse osmosis is slightly acidic and has the healthy minerals stripped away this part of the process makes the water healthier and improves the taste.
- Optional treatment stage or stages- Here is where reverse osmosis systems differ. Some use UV filters to kill microorganisms. There are also deionization/nitrate/arsenic/fluoride filters that can eliminate any trace amounts of hazardous contaminants left in the purified water.
- The Final Carbon stage- This filter is also called the “polishing” filter, and it eliminates any odors or tastes that the acidic reverse osmosis water has accumulated.
Reverse Osmosis Buying Guide
One of the first things to consider searching for reverse osmosis systems is the size of your home and family. Large homes with large families may need a commercial grade system because the use more water. Smaller homes and families can get away with using a portable system or smaller permanent one.
Also, what are the plumbing requirements and how much space to you have available for the system. This two factors will really effect how many options you have. Smaller spaces may not accommodate standard-sized equipment. Does the equipment need to be installed under the sink or can it be installed elsewhere with more space?
Another question to ponder is what type of water source do you have? Is it well water or city water?
Identify the Main Contaminants that You Want to Eliminate
The Safe Drinking Water Act defines “contaminant” as any radiological, physical, biological, chemical or other matter in water. From this definition, you can see that contaminants are considered just about anything. It’s important to remember that that there are healthy “contaminants” in water as well, like minerals.
Is your water source brackish? Are you looking to eliminate more microorganisms? Are there specific contaminants that you’re looking to get rid of such as lead, chromium, rust, etc.? These are some questions to ask yourself before choosing the right reverse osmosis system for your needs.
All systems vary with the amounts and types of contaminants that they reduce or eliminate. Each home or area has problem contaminants specific to them.
Testing your water would be an excellent way to see just what is floating around in your drinking water. Different filters within these filtration systems target specific contaminants, as well.
Contaminates Removed by Reverse Osmosis Filters
Reverse osmosis or reverse osmosis systems are a popular choice for treating water to make safe for consumption. There are many reasons that untreated water could be unsafe for consumption by humans. One of the main areas of concern is the presence of various contaminates in most local water supplies. These contaminates can have a multitude of undesirable health impacts that should be avoided using filtering systems such as reverse osmosis.
Depending on where one resides, it’s a fact that there could be a high level of contaminates in the local tap water that you use for cooking or drinking. The exact nature of these contaminates will depend on your local or regional situation. For example, in the American Midwest, there is a high amount of agriculture that takes place in many areas. Because of this, it’s not unusual to experience a high level of pesticides and herbicides in the local water supply. The reason is that rainfall and natural processes result in runoff of these chemical contaminates into ponds, rivers, and underground water channels.
Other areas of the country may have naturally occurring high levels of sediment or certain chemicals, organic, or inorganic substances. In addition to chemicals and minerals, there’s also a serious risk around the presence of bacteria, viruses, and other biological threats.
It’s worthwhile to review how reverse osmosis systems work so that there is clarity on how the filter works to treat water. The name comes from the fact that in this system the flow of water is reversed and flows from a concentrated solution to one that is more dilute. And this flow of water happens through a membrane is where some of this filtering takes place. It’s important to note, however, that this membrane in this process can’t accomplish all the goals of a robust water filter. Therefore, most reverse osmosis water filter systems incorporate additional stages of filters to do the additional work.
The most popular additional filter that is used in reverse osmosis systems is carbon filtration. This is especially effective at eliminating chloramines. Chloramines are disinfectants that are added to water supplies by municipalities and water utilities to protect public health by killing or inactivating harmful organisms.
There is a long list of things in water supplies that warrant the need for a reverse osmosis system. Whether it’s sediment, biological matter, chemicals, radionuclides, arsenic, asbestos, heavy metals, and many other contaminates, both residences and businesses clearly see the need for effective water filtration to produce healthy, safe, and good tasting water for their needs.
Features and Other Considerations
Based on the contaminants that you want to eliminate and the size of your home and family, you probably have an idea of what you’re looking for in an RO system. Here are some additional considerations:
- Output of water / water pressure / gallons per day (GPD)
- Waste Water
- Tank Size
- Professional versus self-installation
- Number of filtering stages
- Difficulty of installation
Along with those considerations are various features to think about with these particular filtration systems. They are:
- Compact equipment– Some models are built compact to take up less space. Compact equipment may be necessary in apartments and RVs.
- Post Carbon– This feature removes the taste and odor from water after the filtration process. These cartridges contain burnt coconut shells. That’s what gives the water a nice taste.
- Storage Tank– This is where the water is stored after filtration. They are most useful when there is no water or time to make filtered water and allows you to drink what’s in the tank until you can filter fresh water. However, since the filtered water contains no chlorine, it does not prevent bacteria from infecting the water in the storage tank. It’s a good idea to bleach the tank twice a year to disinfect it.
- Flow Control– This helps regulate the flow of water passing through the membrane to increase its lifetime.
- Ultraviolet– A UV feature helps keep bacteria out of your water after its filtrated. Its an alternative to disinfecting your storage tank twice a year. The UV filter is put into the system after the tank and prior to the faucet to eliminate any bacteria from the tank that have migrated towards the faucet.
Some other features include; twist off filters, air gap faucet, TDS meters, rejection of impurities, and shut off.
Reverse Osmosis Installation
Reverse osmosis systems are a popular water filter type and are offered by many different manufacturers that may also have different models for purchase. Because of this popularity, these reverse osmosis systems have become extremely easy to install by most homeowners or business owners. So, there’s no need to fear the installation process. It’s always helpful to be handy, have professional tools, and some specific plumbing knowledge to help the installation activities. But, in most cases, none of these should be necessary to successfully install one of these devices.
The first you always want to do in these situations is to thoroughly read the instructions that are provided by the manufacturer of your reverse osmosis system before you start the installation. You will find information here that is specific to the model and reflects the parts and accessories that come with it. There may also be specific instructions on plumbing configurations, and you need to identify which one you have and what portion of the instructions apply to your situation. Once you’ve reviewed the instructions carefully from beginning to end, it’s time to get started with the installation.
Here, we’ll provide a general overview of the stages involved in installation:
- Turn off the cold water shut-off valve. This is your first step to make sure that water doesn’t enter the process and where you are going to be doing your work
- Next, turn on the cold water at the faucet in your sink to confirm that there is no flow and that water is out of the system
- Remove the water line from the shut-off valve
- Then, use the adapter provided by your system to connect at the cold-water line to provide the feed water to your reverse osmosis system
- Turn the cold water back on at the shut-off valve
- Position your reverse osmosis system’s filter and reservoir tank in your under-sink cabinet space
- Set up the drain line from your system’s filter to the waste line with the included saddle mechanism. You will need to drill a hole into your existing waste line and install the saddle so that the reverse osmosis system can discard its normal amount of water here.
- Use an existing opening on your sink or drill an appropriate hole into your sink area to accommodate the new water faucet for the treated water. Carefully make this hole, if one doesn’t exist. Make sure you have the right tools, use safety glasses, and make sure you have the right tools and drill bits to get the job done right.
- Install the new faucet and under the sink make sure the water line goes to the output of your reverse osmosis system
- Also, connect your reservoir tank to the filter system
- That’s it, you are done!
Here’s an excellent video that illustrates this installation process well:
We recommend after installation that you clean up your work space, put away tools, and check for leaks at all adapters and joints that you’ve created. Then, run the system for about 1 to 2 gallons to make sure the filter is ready to do its job and any sediment or other impurities are out of the system. At this point, you are ready for clean, healthy, and good tasting water from this day forward.
Reserve Osmosis System Maintenance
The beauty of reverse osmosis systems is that don’t require much maintenance to be performed. The main thing you will need to do is replace the filters at some interval and that depends on the level of usage in your home or office. It’s basically a function of how many galls of water the system has treated until you will need to replace the filters to make sure the system functions at maximum intended performance.
Here is a general overview of the filter replacement process:
- Turn off the cold water shut-off valve
- Turn off the valve at the reservoir water tank
- Open the water faucet on the sink to clear out any water in the system and relieve the pressure
- Use your filter wrench to turn the filter to unscrew it from the system housing, start with the first stage first
- Once the first stage filter is clear of the housing, remove and discard the worn filter and insert a new one
- Hand tighten the filter back onto the housing and then finish the tightening with the filter wrench
- Repeat the same steps in 4-6 for each additional stages of filters being replaced
- Finally, open your faucet for 1-2 minutes to flush out an amount of water to be ready for clean pure water again
Again, please note that these are general instructions that will give you a good overview of the process involved in replacing filters on your reverse osmosis system. You should follow the specific instructions that your manufacturer provides for your specific make and model of reverse osmosis filter.
