What is a reverse osmosis system?
The phenomenon of reverse osmosis allows us to enjoy crystal clear drinking water.
Over the years, the technology at RO systems has changed so much that now everyone is able to install a RO filter under their sink and enjoy crystal clear water free of up to 99.99% impurities such as lead, chlorine, fluoride, giardia, hormones, asbestos, sodium, bacteria, arsenic, viruses and more. RO systems are so effective that they can remove even some species of bacteria from the water. For this reason, RO systems are used for the mass production of bottled water.
Reverse osmosis filters are becoming more and more popular every year.
On the internet you can read a lot of opinions about this type of filtering, there are, of course, various myths that we will try to refute.
In the following text, we will describe:
- How reverse osmosis filters work?
- What should we focus on when choosing a filter for our household, and what parts are the most important
- Advantages and Disadvantages
- How to service the reverse osmosis system?
We hope that after reading this article, you will be able to make the best decisions for you and your family regarding shopping and choosing a specific product.
How Reverse Somosis System Works?
Reverse osmosis uses a semi-permeable membrane that passes pure water particles, retaining impurities that are too large to pass through the osmotic membrane micropores. Better quality RO systems use a process called crossflow, which allows the membrane to self-clean. The water does not flow onto the membrane, but flows “along with it,” thanks to which the impurities retained in the membrane are removed along with the contaminated water.
In some models, one can encounter situations when the polluted water goes back to the main water circuit so that it is not wasted as if it goes to the drain. This water can be used to water the plants or to wash some equipment or surface. RO requires a force that pushes water through the membrane, but tap water pressure is quite sufficient for the process to take place efficiently. RO system uses the cross filtration process as opposed to ordinary filters. This is due to the fact that in an ordinary filter, contaminants are stored, which over time affects the lower efficiency of the filter and its faster replacement. In the case of cross filtration, the contaminated water flows in one direction, and the filtered water in the other.
Reverse Osmosis System Step by Step
Reverse osmosis systems have from 5 filtration stages to about 10.
In most devices of this type, the first five steps are crucial to obtaining clean water, and filtration in them usually follows the same pattern.
- Step one – the first stage serves mainly to separate more significant impurities such as rust or stone. A 5-micron filter is usually used here.
- Step two – the first of two carbon filters that primarily serves to remove chemicals.
- Step three – second carbon filter that is much thicker than the first, the water that flows through it is now ready to pass through the RO membrane.
- Step four – is the most crucial moment because it is here that the process of reverse osmosis takes place. The filter is dense enough that elements larger than 0.0001 microns are entirely removed from the water. This also applies to heavy metals; at this point, clean water is separated, and all impurities usually end up in the water outflow.
- Step five – in most RO systems, this is the last stage of water filtration.
This is quite an important stage because chlorine, bacteria, and viruses are removed here.
Occasionally any unpleasant taste or smell is also removed.
Some devices of this type have additional filtration stages.
These are usually filters that are designed to improve the taste of water and add to its minerals, which are unfortunately retained at earlier stages.
It is recommended that you add minerals to the water that has been filtered in such detail because, without them, our body can suffer.
Reverse Osmosis System Installation
Most RO systems are designed so that anyone can install them in their household without having to call for professional help. It should be remembered that the reverse osmosis system is built so that it is kept in a kitchen bench under the sink.
If we plan to mount the device in any other place, we should carefully plan what we will do and equip ourselves with additional parts; it will save us unnecessary stress. An essential factor to keep in mind when installing a reverse osmosis system is the additional tap, which in most cases, we will have to drill ourselves. Some sinks have an additional hole that is covered, in which case it saves us drilling.
Most RO systems have an elementary connection diagram, which we will describe in a few steps below. This should not take more than 30 minutes even for someone who has not been in contact with this before.
Remember, if your reverse osmosis system has a UV lamp, connect the device to a power source.
1. Turn off the water supply valve so that you can avoid unpleasant surprises.
2. Remove the cold water feed pipe
3. Install the T-Connector; it is equipped with every reverse osmosis system
4. The time has come to install the drain connector, to do this it is necessary to drill a hole in the drain pipe. The best place to do this is the horizontal section of the drainage pipe.
5. The next step is to install the filter; you should do it in the most convenient place under the sink. Remember, however, that from time to time, filters need to be replaced, so access to it should be more comfortable.
6. Water tank; it should be mounted in a place under the cabinet so that it does not bother us, it is also important that it is on a flat surface
7. In this step, we proceed to connect all the pipes; it is very simple because the parts are usually selected in colours so that as easy as a possible assembly.
8. At this point, we should have all the pipes connected, and we can start the water cycle. It is worth checking that nothing is leaking from any position.
9. Before we can enjoy clean water, you need to fill the tank and empty it, depending on the model it maybe once and it may be several times.
I remember not to drink water until you do it.
To facilitate the installation process, even more, we present a video in which you can see precisely how a professional is dealing with everything.
How to service reverse osmosis system?
A specific feature of all water filters is that they have a specified lifetime, which means that their efficiency may decrease. This is usually due to overloading the number of contaminants in the filter. The consequence of this is the inability to stop contamination through our filter or a significant decrease in its efficiency.
For this reason, it is good to focus on regular maintenance and service of reverse osmosis systems. All activities are so simple that we can easily handle them. Also, thanks to the new preparations, they do not have to take a lot of time and absorb our attention.
Replacing cartridges is a very important step that you need to perform regularly. This is a prerequisite for proper reverse osmosis. Depending on the water quality, such activities should be carried out once every six months or once a year. A more frequent service is provided for users of their own intake. This is due to the fact that the water from the well is not pre-treated in any way, so the cartridges in the reverse osmosis system have more dirt to absorb, which causes them to lose their filtering properties faster. In the case of water coming from the mains water and mainline in the building, their condition is often so good that the reverse osmosis cartridges need to be replaced once a year because they are not so heavily loaded with pollution.
It is worth writing here about the types of cartridges that should be listed in reverse osmosis systems.
Mechanical cartridges are responsible for filtering large particles of dirt from water. Their average service life is half a year.
Carbon cartridges have a much higher durability; they can withstand about a year of regular water filtration
Depending on the number of filtration stages, other types of filter cartridges may also appear. Replacement should be following the instructions of the manufacturer of RO.
In addition to the cartridges, there is also an osmotic membrane, i.e. the heart of every reverse osmosis system. This element is very durable. Good quality osmotic membranes can work without any problems, even for about five years.
Pros and Cons of Having a Reverse Osmosis System
– Perfect for cooking – A common problem when you have hard water is the fact that the precipitating sediment is visible on food in the form of white filings.
With Reverse osmosis system, we can avoid this and enjoy healthy food without stone.
– Permanent access to freshwater– purified water collected using the supplied tap that. Thanks to this, we have the gravity of freshwater whenever we feel like it.
Thanks to this, it is not necessary to buy water packs, which translates into space-saving and eliminates the hassle of too much paste in the trash.
– Money savings – reverse osmosis systems are recommended to all those who consume large quantities of bottled water. Thanks to reverse osmosis, we can fill one bottle with water infinitely, which also helps to reduce the littering of the environment.
– Ideal for rinsing and washing – purified water thanks to the reverse osmosis system is particularly suitable for washing vegetables and fruit. It is excellent for cleaning glasses as it does not leave stains.
– Best for household appliances – it is worth using reverse osmosis water to top up your iron, steamer or coffee maker. The stone that accumulates in the equipment shortens its service life.
– Space under the sink – an important disadvantage is a free space under the sink. RO system usually consists of filters and a water tank that must stand on a stable surface in an upright position.
It is also worth remembering that reverse osmosis must be connected to the sewage drain.
– Operating costs – remember that cartridges are not eternal and need to be replaced regularly; otherwise our system will run less efficiently
– Minerals – an osmotic membrane in the process of water purification removes most of the components, including minerals. However, do not worry too much because most minerals are consumed with food anyway and if we care about water rich in minerals, we can add them on our own.
Reverse osmosis water filtering systems provide one of the best solutions for your home in terms of purity of filtered water.
In recent years, domestic reverse osmosis systems have evolved to such an extent that we are able to install, service and operate the device without professional assistance.
Thanks to the reverse osmosis system, we can afford to consume water without up to 99% of pollution, while protecting the environment, which we can owe to reducing the purchase of bottled water.
We recommend this solution to everyone who cares to live a healthy life.
