What is Reverse Osmosis?  

Reverse osmosis is a process of filtration that removes impurities from water by using pressure to force it through a semipermeable membrane. The water forced from the more concentrated side of the RO membrane to the less concentrated side is referred to as the permeate. The wastewater that is left over, containing all of the filtered out contaminants, is called the brine. 

A semipermeable membrane has small pores which act as a barrier to impurities but allow water molecules to flow through. In osmosis, water becomes more concentrated on one side of the membrane as it seeks to achieve equilibrium. However, in reverse osmosis the process is reversed and contaminants are prevented from entering the less concentrated side of the membrane. For example, when pressure is applied to a volume of saltwater during reverse osmosis, the salt is forced back and only clean water flows through.

How does a Reverse Osmosis system work?  

Reverse osmosis systems are used to remove sediment, chlorine, and dissolved solids from water. A prefilter removes large particles before the water is forced through a semi-permeable membrane. The water then passes through a postfilter to remove any remaining impurities before being dispensed from a dedicated faucet. 

Stages of RO systems

RO systems typically have 3, 4, or 5 stages of filtration. The first 2 stages for our Aqua Chill Reverse Osmosis system includes a sediment filter and carbon filter.  Technically, the first 2 stages are a pretreatment before flowing into the RO membrane which is stage 3 filtration.  

Different types of filtration systems exist, each of which contains one or more of the following filters: 

    • A sediment filter, which reduces particles like dirt, dust, and rust.   
    • A carbon filter, which reduces volatile organic compounds (VOCs), chlorine, and other contaminants that give water a bad taste or odor.   
    • A semi-permeable membrane, which removes up to 98% of total dissolved solids (TDS).

1. When water enters an RO system for the first time, it passes through a process called prefiltration. This usually includes using a carbon filter and sediment filter to remove any sediment or chlorine that could clog or damage the RO membrane. 

2. After that, water passes through the reverse osmosis membrane where dissolved particles smaller than what can be seen with an electron microscope are taken out.  

3. After the water has been filtered, it flows into the storage tank where it will be kept until it is needed. The reverse osmosis system will continue to filter the water until the storage tank is full and then it will shut off.  

4. As soon as you turn on your kitchen sink faucet, water flows from the storage tank through another postfilter to disinfect drinking water before it reaches your faucet.

What are the benefits of having an RO storage tank  

Reverse osmosis water is stored in an RO storage tank so you have a plentiful supply whenever you need it. A reverse osmosis system produces water slowly, at a rate of two to three ounces per minute. If you were to turn on your faucet and try to fill a glass of water at the actual membrane production rate, you would have to wait at least 5 minutes for it to fill. However, with a storage tank, your glass fills instantly.

What does a reverse osmosis system do?  

Reverse osmosis systems are designed to remove dissolved solids, like arsenic and fluoride, from water using an RO membrane. In addition to the RO membrane, these systems also include sediment and carbon filtration for broad-spectrum reduction. The carbon filters in an RO system help to remove chlorine, bad taste, and odors from water, while the sediment filter removes dirt and debris. 

A reverse osmosis system eliminates …  

    • PFOA’S? Yes, Eliminate that pesky chemical.  
    • Fluoride? An RO system can help with that.   
    • Salt? Yep, it’s on the list.   
    • Sediment? You bet.   
    • Chlorine? Absolutely.   
    • Arsenic? Yes, indeed.   
    • VOCs? Yes, indeedy.   
    • Herbicides and pesticides? The RO system can handle those, too.  
    • What about the other contaminants? The ones I listed are some of the most popular ones that get treated with an RO system, but the system can also remove a ton of other contaminants.  
    • Bacteria and viruses in your water? No way. If your water comes from a city treatment plant, then it should already be microbiologically safe. Reverse osmosis will remove bacteria.  

What are Reverse osmosis system benefits? 

RO systems are extremely effective at filtration, removing 98% of all dissolved solids. This makes for healthier drinking water overall. Water distillers also reduce TDS levels, but are less efficient than RO systems.  

    • Harmful dissolved contaminants are lowered with this system   
    • Sodium is also reduced, leaving you with safer water to drink   
    • It not only improves the taste of your water, but gets rid of any unwanted odors   
    • It’s more environmentally friendly than relying on bottled water   
    • Installation and maintenance are easy, and it doesn’t take up much space

Does water waste through reverse osmosis?  

A reverse osmosis system eliminates water contaminants that other filters may leave behind. As water flows through the system, it is split into two streams. One stream carries filtered water to a sink faucet, while the other stream takes removed salts, pollutants, and minerals to the drain.  

The brine, or “wastewater,” from a reverse osmosis system carries rejected contaminants to the drain. For every gallon of water produced, 2-3 gallons exit the drain. However, this wastewater serves a purpose; it helps clean the water, just like how dishwashers and washing machines use water to clean dishes and clothes respectively. Nevertheless, it is crucial that we minimize the amount of water sent to the drain and increase the efficiency of the RO system in order to care for the environment.  

Here are some tips to help reduce wastewater in an RO system:  

    • Ensure that your system is properly maintained and that all elements are functioning as they should be. This will help to minimize the amount of wastewater produced.  
    • Be mindful of the water input and adjust accordingly. Too much water input can lead to increased wastewater output.  
    • Try to use only the amount of water necessary for your specific needs. Excess water usage will result in more wastewater being produced.  
    • Monitor the effluent closely and make changes as needed. This will help to keep wastewater production at a minimum.  

How RO Systems Benefit the Environment?  

Reverse osmosis systems can have a positive impact on the environment in several ways. RO systems can help to reduce water consumption, lower energy use, and reduce the amount of wastewater produced.  

Lowering water consumption is perhaps the most obvious way that RO systems can benefit the environment. By using an RO system, you can reduce your water consumption by up to 50%. This can have a significant impact on water resources in areas where water is scarce.  

In addition to reducing water consumption, RO systems can also help to lower energy use. Running an RO system takes less energy than boiling water or using other methods of purification. This means that using an RO system can help to save energy and lower your carbon footprint.  

RO systems can also help to reduce the amount of wastewater produced. When you use an RO system, very little wastewater is produced because most of the water is purified and used again. This means that there is less water waste overall, which can be beneficial for the environment.  

After the water you use runs down the drain in your home, chemicals and other pollutants need to be gotten rid of before it can be recycled. Wastewater is either taken to a water treatment plant where it is diluted so it will be simpler to treat or else it is sent to riverbeds where nature filters it through the hydrologic cycle.  

A reverse osmosis system can help to make waste treatment more efficient. The reverse osmosis water that is drained from your home is typically already free of chemicals, as they have been removed during the carbon filtration stage. The leftover brine water has just a slightly higher concentration of dissolved inorganics. RO systems can help to speed up the recycling process because no new chemicals are introduced into the water supply after RO water drains from your house.

Bottle water or Reverse Osmosis? Which is better for you?  

Reverse osmosis and bottled water each have their own benefits. However, depending on your needs, one may be better suited for you than the other. Here we will compare the two methods of water purification to help you decide which is right for you.  

Reverse osmosis forces water through a semipermeable membrane, leaving contaminants behind. This results in clean, safe drinking water. However, the process also removes beneficial minerals from the water, making it less refreshing to drink.  

Bottled water is another option for clean drinking water. While it is not as “pure” as reverse osmosis water, it does still go through a filtration process. In addition, bottled water usually has minerals added back in, giving it a more natural taste.   

Many people don’t realize how much water goes into making a single bottle of water. It takes quite a bit of water to purify the water through reverse osmosis, and even more water is used in the production of the bottle itself. Petroleum is also used in the process, which can be harmful to the environment. A reverse osmosis system doesn’t have as high of a cost to the environment and provides water that tastes just as refreshing.  

Reverse osmosis has many benefits, one of which is that it produces purified water in your home. There is no need to buy bottled water, which is expensive and wasteful. A reverse osmosis system produces bottled water quality hydration in the comfort of your kitchen. You can even fill stainless steel water bottles with RO water and store them in your fridge, so you can enjoy all the conveniences of bottled water without the disposable single-use plastic bottles and weekly grocery runs.  

So, which should you choose? If you are looking for pure drinking water with no additives, reverse osmosis is the way to go. However, if you want water that tastes more natural and has added minerals, bottled water may be a better option for you.  

Is RO water good for you? A Closer Look at the Pros and Cons

Every day, we are inundated with choices to make. Some of these are small and have little consequence, like what to wear or what to eat. Others are much more significant, like whether or not to get a particular medical treatment. But whether big or small, all decisions require us to weigh the pros and cons before making a choice.  

The quality of our drinking water is important to many of us. For example, when choosing between RO water and tap water, which is better for you? RO water is filtered using reverse osmosis technology, while tap water goes through municipal filters. Let’s compare the pros and cons of each option to help you make an informed decision. 

Reverse osmosis is an effective way to remove dissolved contaminants from water. By filtering the water before it enters your body, reverse osmosis can help keep you healthy and free from harmful contaminants. Although reverse osmosis removes beneficial minerals like calcium and magnesium from water, the resulting water is still safe to drink.  

Our bodies are made up of 70-80% water, which hydrates and lubricates our joints and aids organ function. You don’t need minerals to do those things – you would have to drink excessive amounts of water for your body to absorb enough mineral content to make a significant difference. Food is the primary source of essential nutrients, not water. If you want more minerals, eat your fruits and veggies.  

The EPA recommends that the amount of TDS in water not exceed 500 parts per million. However, a large number of Americans have TDS levels that exceed this limit. As a result, they could potentially benefit from using an RO system.  

Where to use a Reverse Osmosis system 

Under the sink is a great place for your reverse osmosis system. This is because it is out of the way and can be easily installed. Plus, a point-of-use RO system could also be mounted in a cabinet or remotely in the garage or basement.  

Adding an under-sink reverse osmosis system to your refrigerator is an easy way to improve the quality of your ice and drinks. This type of system eliminates minerals from water, resulting in clearer ice and more refreshing beverages.  

In most cases, reverse osmosis is not necessary to treat water for an entire house. Although an RO system can remove specific contaminants, such as saltwater intrusion in a well or high levels of silica, using this method may be excessive unless your water contains a certain pollutant.  

Although an RO system is not capable of pressurizing water for an entire house, there are other ways to achieve this. In some cases, a whole-house RO system may be necessary. In this instance, a large booster pump, such as a Grundfos or Davey, can provide adequate water pressure. In addition to the pump and storage tank, a UV system is also needed to disinfect the water once it leaves the tank.  

Homeowners need to consider several factors when buying a reverse osmosis system for their entire house. If the water quality is bad enough that it requires whole-house RO, other water quality issues will probably have to be fixed before the water gets to the RO membrane. Hard water will cause scale build-up on the membrane, which reduces performance and causes it to fail sooner. Contaminants like iron can also damage the membrane, so they must be removed from the water before it goes through the RO system.  

Are you concerned about the quality of your water? If you think it may require whole house reverse osmosis to treat, be sure to check out our guide. You can also find out more about how water booster pumps work.  

What is the best way to filter shower water? If you have a small storage tank, reverse osmosis may not be the best option. A simpler solution is usually to focus on removing chloramines from the water, which can be done with a whole-house catalytic carbon filter. 

Unfiltered water can often be the source of an lackluster shower. Soap typically doesn’t create a rich lather in water with a high mineral content, and hard water can leave hair feeling limp and dull. Installing an ion exchange water softener will eliminate these contaminants.  

You only need an RO system for your pool if the water contains a contaminant that cannot be removed by any other filtration system. Otherwise, other systems will do a better job of providing clean pool water. 

Reverse osmosis can be beneficial for agriculture. RO water can be ideal for greenhouses or small gardens. Hydroponic farming necessitates pure water to be successful. By using RO water, farmers can control their plants’ nutrient intake better. 

Do you get your drinking water from a private well? If so, then an RO system is an excellent way to ensure that the water flowing to your tap is safe. A reverse osmosis system can remove difficult contaminants often found in well water, like nitrates.  

Do Businesses use reverse osmosis? Absolutely.   

Reverse osmosis systems are very common in commercial and industrial settings because they allow drain water to be recycled back into the feed supply. This process is also great for removing paints, dyes, and other industrial contaminants.  

Are you looking to create an optimal environment for your aquarium? If so, reverse osmosis (RO) is the perfect solution. RO systems strip all minerals from the water and allow you to add back in the exact amount of salt needed with a demineralizing filter. This combination of reverse osmosis and deionization (RO/DI) creates highly pure water that closely resembles the natural habitat of your fish.  

Do RVs have RO systems? Yes, they can be very helpful for those whose RV adventures take them into more remote, wilderness locations. A reverse osmosis system can remove harmful bacteria and particulate matter from water. Storage tanks are difficult to attach to RVs because drain hookups aren’t located at campsites, but it is possible to find a workaround.

Reverse osmosis system or a water softener?  

When it comes to choosing between a reverse osmosis system and a water softener, there are pros and cons to each option. A reverse osmosis system will remove impurities from your water, but it can also remove some of the beneficial minerals. A water softener will not remove impurities, but it will make your water feel softer and can extend the life of your appliances.   

There are a few key differences between a reverse osmosis system and a water softener – the most notable being that water softeners do not filter out harmful contaminants. Instead, they target calcium and magnesium in order to soften hard water and make household tasks like laundry and showering more manageable.  

Hard water is a common issue that homeowners face. While reverse osmosis can soften water, it’s not recommended for hard water (above 7 grains). This is because it puts strain on the RO membrane and shortens its lifespan. If you have hard water, using a water softener is a better option.  

Reverse osmosis systems can actually benefit from water softeners. Installing a water softener before the RO system can actually remove iron from the water that would otherwise stain your shower, clothes, and toilet orange. Not to mention, it can also clog the RO membrane. However, an RO system can remove sodium added by the water softener.  

What is the lifespan of a reverse osmosis system?

Reverse osmosis systems have a longevity of approximately 10-15 years. However, the RO membrane and filters need to be swapped out periodically. Prefiltration and post-filtration should take place every 6 months to 1 year, while the RO membrane may need replacement every 2-4 years depending on water conditions.
