What is Reverse Osmosis?
Reverse Osmosis is a process used to remove impurities from the water by pushing them through the permeate membrane. When the water passes through the very thin layers of the membrane, it filters out contaminations.
This process removes many dissolved contaminations and chemicals while pushing the water through the very thin layer of permeate membrane. The permeate membrane filters out all the impurities which are larger than the water molecules.
Reverse Osmosis is used to purify the water from more than 1000 contaminations, eliminating all the odors, gases, and TDS from the water.
How does the Reverse Osmosis System work?
The Reverse Osmosis system filters out any contaminants like chloride, dust, viruses, etc from water.
This system consists of the main 3 stages of filtration to provide you with healthy drinking water. These three main stages consist of pre-filters, RO membranes, and post-filters.
Water flows through pre-filters to remove the large contaminants, sand, and dust before going into the membrane.
In the next stage, the water passes through the thin layers of the RO membrane, which removes all the particles that are larger than 000.1 microns. Basically eliminating all the particles except for water.
In the post-filtering, the purified water passes through a carbon-based layer that removes any bad taste and odor from the water, making the water contaminants-free and pure.
Several systems follow these 3 main purification filtration processes in 7 stages. Let us see how the Reverse Osmosis system works step-by-step in 7 stages.
- Sediment Filter– Water passes through the sediment filter and removes large particles like rust, dust, sand, etc. so that the water can be sent through a permeate filter.
- Carbon Filter– This filter eliminates chemicals like chlorine from the water making it safe to pass through permeate membranes.
- Carbon Block Filter– The water passes through the carbon block filter to remove all the pesticides, fertilizers, and insects which are too small to spot with human eyes.
- Reverse Osmosis Membrane– This is the main stage of the Reverse Osmosis system. The Reverse Osmosis membrane has small holes, when the water passes through this membrane it removes all the molecules which are larger than 000.1 microns.
- Removal of Impure Water– In this stage, the impure water is discarded by the system via a separate pipe so that it doesn’t enter the next filter.
- Remineralization– This process is skipped in some of the Reverse Osmosis systems. Remineralization adds extra minerals back into the water, these minerals can be calcium, potassium, etc. Not only does it make the water healthy but it makes the water taste better.
- UV Light Filters– This filter is optional. Ultraviolet light removes all the microorganisms which somehow manage to pass through the permeate membrane and gives you highly purified water.
There are many other optional customizations you can choose for your Reverse Osmosis system.
- Some of the systems come with a water storage tank. Without the water tank, you will get the water filtered in real-time. But if you want to get a system that occupies less space in your home, then you should opt for the tankless system.
- Remineralization filters are also customizable in some systems. You can choose the minerals you want to have in your water and you can get a remineralization filter based on your needs.
- Some of the systems come with high-pressure pumps to have fast-flowing water on your tap.
- There are some systems that come with lead-free faucets if you do not wish to use the same faucet in your sink. Using the lead-free faucet will reduce the risk of contamination and chemicals coming into the water because of the surface of the faucet.
What to look for when buying the Reverse Osmosis System?
There are several points that can help in choosing which RO system is best for your requirement. It is necessary to first identify your requirements with the Reverse Osmosis System.
Firstly you will have to find answers to the questions like,
The RO System with or without Tank
It is necessary to identify if you need an RO system that occupies less space in your home. Several systems come without the tank and are compact in design. If you want to purchase a system with a tank, it is necessary to make sure what kind of tank size you will need. These tanks come in capacity from 3 gallons to 14 gallons.
Installation
First, you will need to figure out if you wish to buy a system that needs a plumber to make it work or, do you want something like a do-it-yourself (DIY) installation. Based on this you can choose a system with easy installation and customer support.
Customizable system
Several brands offer customizable systems via which you can get a system that meets your needs perfectly. While choosing a customizable system it is necessary to identify the factors like water source, filters, space, etc
Your needs for the system
Before choosing a system, it is necessary to decide for what purposes do you want to use the Reverse Osmosis system. Do you want the system for drinking? Attaching it to the refrigerator? For your aquarium?, or Do you want a system just for your kitchen or your whole home?
After identifying answers to these questions, there are several other points that should be considered before buying the Reverse Osmosis System, let’s see what are those:
The Lifespan of Filters and Filter Stages
When it comes to filters there are certain different filters with different lifespans with each system. You have to choose a system with filters, which has more lifespan and capacity. There are several filters that come with a limited lifespan becoming a reason for continuous expenses on the filters.
The stages of the filter identify the purification of the water. Any system with more than 6 to 7 stages is an idle system to choose to get highly purified water. There are certain systems that come at a reasonably cheap price but filter change becomes a hassle. Before buying a system you will have to check on the process of filter change and the cost of these replacement filters.
Water wastage
So many RO systems have a high ratio of water waste to purified water. When you choose a system with less water waste, you decrease your water bill significantly. Wastewater is one of the setbacks of the Reverse Osmosis System. There are systems that produce wastewater up to 25 gallons to purify 1 gallon of water. This wastewater contains a high amount of contaminants making the water useless. So, it is necessary to look for a system that has a minimum ratio of water waste to purified water.
The Flow of the water
Even the most expensive RO filters have low water flow compared to the non-RO filters. Some systems fill your cup in 12 seconds whereas some systems take more than a minute to fill up your cup. The reason for low flows can be because of different reasons like water source, flow pump, etc.
Capacity of the system
Before you choose the water filter to install in your whole house, you will have to identify the need for water quantity in a day. Some systems have the capacity of producing 75-90 gallons of pure water in a day whereas some systems have the capacity to produce 12 gallons of pure water in a day. Identify your usage capacity and choose a system that matches it perfectly.
Remineralization
The Reverse Osmosis system purifies water of any impurities, but sometimes some consumers face health challenges due to demineralized water. If you are keen on having minerals in your water always choose a system that uses mineral filters to remineralize your water.
Size of the System
There are several sizes available in the market for RO systems. Some systems occupy very little space whereas some RO systems fill up your under-sink space with their set-up. If you are looking for a system that requires less space but still works in seven stages of purification, you will have to choose a system with advanced technology. Sometimes the systems which require less space are made with advanced technology costs higher than any regular systems.
Different components of the Reverse Osmosis system
Pre-filters
Pre-filtering is the first and important stage of the reverse osmosis system. Pre-filters remove large contaminants from water before the water enters the RO membrane. Without the pre-filter, the lifespan of the RO membrane can be really short.
RO membrane
When the water passes through the RO membrane it removes all the chemicals, viruses, bacteria, etc. RO membrane generally removes contaminants that are larger than 0.0001 microns.
Post-filters
Post-filters are the filters situated between your storage tank and your tap. It removes carbon or any other substances in the water ensuring better-tasting pure water.
Storage tank
Certain RO systems have storage tanks among their components. Once the water is purified in the RO system, the purified water is stored in this tank. Some people choose not to install storage tank in order to save space.
Shut-off Valve
Without the shut-off valve, your kitchen would probably flood. A shut-off valve is usually automatic, making sure to stop the water from filling inside the storage tank once it’s full.
Faucet
Most of the companies producing RO systems suggest switching your old faucet with a new one. Switching your current faucet with the one which comes with the system can eliminate the risk of lead in your purified water.
UV light
UV light is usually considered one of the most important post-filters. UV light kills remaining microorganisms that somehow found their way through the RO membrane.
Water pressure pump
If the input of the water is low then the output is going to a low water flow. Installing a water pump helps in increasing the water flow hence water filtering capacity.
Permeate pump
A Non-electric permeate pump ensures that the water wastage is less. Making the water waste as minimal as possible
Electric pump
Like the permeate pump, an electric pump ensures that the minimum amount goes down the drain. It has the same work as the permeate pump, the only difference is that the permeate pump is non-electric.
Advantages and Disadvantages of Reverse Osmosis System
A reverse Osmosis System doesn’t come cheap. Now the main question is if the Reverse Osmosis system is really worth spending your money on it.
Let us see the pros and cons of the RO System.
Advantages
Easy Installation
Almost all RO systems come with an instructional manual and instructional videos to help you set up the system in your kitchen or basement.
Gives amazingly purified water
The RO system removes 99.9% of the water contaminants and chemicals in the water, giving you odorless and tasty purified water.
Less expensive than bottled water in the long run
Some RO filters cost a fortune while some are way cheaper. RO systems are a one-time investment, after that, you will just need to change filters after their expiry. Overall in a long span of time, the cost of having an RO system is less than purchasing bottled water.
Easy access to mineral water at all time
If you purchase an RO system with remineralization filters, you can have healthy and pure mineral water at all times in your tap.
Disadvantages
Expensive than a regular filter
The Reverse Osmosis filter costs more than the regular filter.
Requires Filter change every few months
While the system gives purified water, it also requires timely filter changes which can be a little frustrating for people.
Removes minerals from water
If there’s no remineralization filter installed in the system, the purified water will have no minerals at all.
Water Wastage
One biggest drawback of the RO system is water waste. The lowest water waste ratio in some RO systems is 1:1 to 1:3 in the latest systems.
Installation and Maintenance of the Reverse Osmosis Filtration System
Some people prefer to hire a plumber for the installation of the system although it is fairly easy to install by yourself, so many companies provide instruction manuals and instructional videos to make the installation hassle-free and quick.
The installation process takes up to 1-2 hours. Here are the steps to guide you for installation.
Choosing the space for installation.
First, you will have to decide on the place you want to install the system. Most of the time people install the system under the kitchen sink to get purified water from the kitchen sink tap. You can also put it in your basement and get the pipe through the floor to tap.
Disconnect the current water faucet and turn off the cold water line.
Before you begin to install your system, make sure to disconnect the cold water line. Also, do not forget to disconnect the water pipe which is connected to your tap.
Connect the system with a waterline.
After disconnecting the waterline with your sink’s tap, now it’s time to connect the system with the waterline.
Connect the drain line.
Once you are done connecting the waterline with the system, you would want to connect your drain line with your waste pipe. Make sure to fasten it properly so it won’t leak.
Install the faucet which came with the system.
It is advised to use the tap which came with the system. Usually, the tap which comes with the system is lead-free, connecting your system to the old tap does not guarantee clean and pure water. You can remove your current tap and install the new faucet in its place or you can drill a new hole to install the new process.
Set the system in place.
After making sure that the previous steps are followed perfectly, set the system in place of your desired location.
Install the tank.
If your system includes the water tank, connect the tank to the filters and the tank’s line to the tap. In some systems the water tank comes connected to the filters, when it does, make sure that the lines are tightly connected and connect the line of the tank to the water faucet.
Plug the system.
If your system works on electricity make sure to plug in your system to the electric outlet after you are done installing the system.
System check.
Once you’re done turn on the valve slowly and check if any pipe or line is leaking, if anything leaks, secure those lines.
Flush the water tank after installation.
Almost every Reverse Osmosis system provider advises filling and emptying the tank after installing it. This can be different with each system. For some systems, it is advised to flush the tank more than once.
Check the manual guide for your system. If you have a tankless system, it is advised to let the water flow from the tap as long as it is advised in the system’s manual instructions.
Maintenance points to consider after installing the system
You will have to maintain changing the filters from time to time based on your water source and usage. On average these filters need to be changed every 6 months to 12 months. The RO membrane filters should be replaced every 2 to 3 years.
Some of the system models come with transparent filter cases, you would just have to keep an eye on the need for filter changes at intervals and change the filter when required.
Some faucets come with LED light indicators when the system needs attention or filter change. Make sure to keep a watch on the colors of the tap to change the filters at the required time.
Frequently Asked Questions (FAQ)
Q. How does the Reverse Osmosis System work?
