What is Reverse Osmosis?
Reverse Osmosis is a water treatment process that removes contaminants from unfiltered water sources by applying pressure to force water molecules through a semipermeable membrane. In general, water flows from a slightly more concentrated side of the reverse osmosis membrane to less intensive side to produce clean drinking water.
The clean water produced after the filtration process is known as permeate, while the concentrated water left over is known as brine or waste.
A semipermeable membrane consists of small pores that effectively block contaminants while allowing water molecules to pass through. In the osmosis system, water is more concentrated while it passes through the membrane to acquire equilibrium on both sides. However, the reverse osmosis system entirely blocks the contaminants to enter the less concentrated side of the layer.
How Does a Reverse Osmosis System Work?
Basically, a reverse osmosis system eliminates chlorine and sediment from the water with a pre-filtration technology before it forces water through a semipermeable membrane to get rid of dissolved solids. After water comes out of the membrane, it passes through a post-filtration system that refines the water before it enters the faucet. Depending upon the pre-filters and post-filters of the product, RO systems may have several stages of the filtration process.
Stages of Reverse Osmosis System
In general, a reverse osmosis system consists of three major phases — pre-treatment, reserve osmosis, and post-treatment. However, few reverse osmosis systems also include several additional stages for extra purification. With every stage, water passes through the different treatment process before it comes out of the faucet for consumption. In this section, we’ll explain the purpose of each stage of filtration in RO systems:
First, the contaminated water is pre-filtered with a sediment filter in order to eliminate larger particles in the water, including calcium carbonate and rust. The sediment filter also acts as a shield to the filter that comes after it, as it removes harmful contaminants that could possibly affect them. Keep in mind that this filter should be replaced every six months, as this is the first thing that comes in contact with the contaminated water.
Carbon Filter with Activated Carbon
After the sediment filtration, the water has to go through another pre-filter process with a carbon filter. The activated carbon effectively filters organic chemicals, chlorine, and oils that can degrade the composite membrane used in reverse osmosis filters. If these contaminants pass through this process, it will damage the pores on the membrane, making it highly ineffective.
Reverse Osmosis Membrane
In the reverse osmosis stage, most of the contaminants are eliminated from the water. This process effectively removes organic as well as inorganic compounds, including arsenic, lead, fluoride, cysts, and copper. Most importantly, it reduces Total Dissolved Solids (TDS), which contains inorganic salts such as sodium, calcium, and magnesium.
Although the water becomes highly pure once it passes through the reverse osmosis membrane, it still remains slightly acidic. Therefore, a remineralizing filter is used to balance the pH level and improve the aftertaste by introducing healthy minerals, such as magnesium and calcium in the water.
Once the water passes through the major purification stages, this is the process of storing it. This is the final stage of the purification process in most reverse osmosis systems. However, a few systems might include additional stages for further purification.
UV Filter (Optional)
This additional UV filter effectively destroys microorganisms and harmful bacteria to protect against biological contaminants. This additional UV rays destroy illness-causing microorganisms and produce highly purified water.
Color Changing Resin Deionization Filter (Optional)
This additional filter removes the remaining TDS from the membrane filtered water. While the RO system removes the larger particles, there are still some TDS left in the water.
Final Carbon Filter
This stage is also known as the ‘polishing’ filter. In this stage, the final carbon removes the unpleasant taste and odors from the water. It also eliminates the rubber particles from the storage tank that may have been dissolved in water during the RO stage.
Reverse Osmosis Water Benefits
Effectively Removes Waterborne Contaminants
Reverse Osmosis systems are 99% efficient when it comes to eliminating waterborne contaminants and pollutants to produce safe and clean drinking water. The semipermeable membranes processes and isolates bacteria, viruses, ions, and heavy metals from water.
Produces Odor-Free Water
While regular filtration systems are ineffective in removing odor from water, Reverse Osmosis systems remove the aftertaste and improve the taste of water. RO systems are equipped with activated carbon filters that attract the odor-causing contaminants and filters them out to produce purified water.
Removes Inorganic Molecules
While most of the regular filters use carbon cartridges that do not remove inorganic compounds, Reverse Osmosis systems are highly effective in removing inorganic molecules with its high-performance membrane.
Extremely Easy to Maintain
The benefit of having a reverse osmosis system over a regular filtration system is low maintenance. While the ordinary filters require frequent washing and rinsing, RO systems are regularly washed by the system itself. This innovative concept makes RO systems convenient for household purposes.
Long-Lasting and Economical
Reverse Osmosis systems usually last longer than regular water filters. As the system itself washes and rinses the membranes of RO, it can easily last for a couple of years. Additionally, it is also relatively economical as this system requires minimal maintenance compared to typical filtration systems.
Option for UV Radiation
UV Radiation is hands down the most effective way to disinfect water. While regular filters do not use UV technology, some RO models have UV lamps that whip out bacteria and viruses.
Things to Consider While Buying a Reverse Osmosis System
While Reverse Osmosis systems are highly effective in purifying water, they may vary when it comes to efficiency. With so many options in the market, it might be a tough call to choose the right one for you. Here are a few things you need to consider while buying a reverse osmosis system.
If you’re planning to use a reverse osmosis system to purify water that comes from a treatment plant, an entry-level system will be sufficient for you.
However, if you’re planning to use the system to treat well water, which has a high concentration of contaminants, you will require a high-quality reverse osmosis system that includes a UV light sterilizer.
Stages of Filtration
Most reverse osmosis systems have three stages of filtration. However, some system features additional filtration stages for high performance. For most applications, the RO system with four-stage filtration technology is more than sufficient. However, if you’re willing to filter well water that contains high levels of sediments, a five-stage reverse osmosis system is highly recommended for additional pre-filtration to get rid of the residues.
Budget is probably the most obvious thing you need to consider while buying a reverse osmosis system. Before purchasing a system, we recommend you to consider both initial costs as well as the maintenance cost. The initial cost is the price of the system, whereas the maintenance cost involves filter replacements and faulty parts. If the unit requires frequent replacement, it will be costlier in the long run.
Due to technological differences, the reverse osmosis system has variation in rejection ratios. The pre-filtration and post-filtration usually determine the effectiveness of the entire system. While most manufacturing companies claim that their RO system can effectively remove 99% of contaminants, you can measure the effectiveness of the filter using the TDS meter. You can also check the quality of the filter by checking if the RO system is certified by a renowned institution.
The water flow rate is another significant thing you need to consider while investing in a reverse osmosis system. Each system will have a different flow rate that will determine how much water the system can purify on average. This usually depends on several factors, including water temperature and water pressure. It is crucial to keep in mind that a system with 50 GPD-rated (GDP - Gallons Per Day) will be sufficient for a common household, but a family of 8 to 10 will require a system that offers twice the GDP rating with 90 to 100.
Reverse osmosis systems comprise of multiple filters, each responsible for removing specific contaminants. This water treatment system removes copper, lead, sand, fluoride, magnesium, and VOCs from the unfiltered water to produce safe drinking water. Additionally, it also removes odors and bad taste from water.
While the reverse osmosis system whips out harmful pollutants, it also removes some essential elements from water. It removes magnesium and calcium, which are particularly beneficial for your bones. However, the filtration device itself does not bring any risk to your health.
During the process of filtering water, the RO system separates the waste and contaminants that are present in water. So, the wastewater is probably the most obvious environmental impact of the RO system. Not only that, for every two gallons of filtered water, about eight gallons go into the water waste system. So, an extensive amount of water goes to waste during the filtration process of RO systems. However, if you use the wasted water for other general purposes, this impact is easily solvable.
A unit can virtually last forever if you use it diligently with regular maintenance. However, you may require to replace the filters frequently to get the optimum output of the RO systems.
Reverse osmosis system and water distillers are two different appliances with a different mechanism, but with similar end results. While RO systems use a semi-permeable membrane to filter water, distiller boils the water then condenses its steam to purify it. However, they both serve the similar purpose of producing highly pure drinking water.
Well, that’s all about the best reverse osmosis systems in the market today. To wrap things up, all these RO systems are engineered to deliver fresh, clean, and safe water, whether you choose to use it at your home or the office. No matter which of these products suit your preference the best, all these RO systems are high-end units that guarantee highly purified water for consumption. But if you still are confused whether you need whole house reverse osmosis system, we recommend you read this article written on Do I need a whole house reverse osmosis system, might it change your mind.
