Reverse Osmosis Water Filtering System in Australia – What is it?
Before you purchase a reverse osmosis water filtering system, it is crucial that you know what this system is and how it works. Most people have heard about the RO system but do not know how it works or what it does exactly. This section of the review will clearly explain how the RO system works and the basics of the RO water filtration system.
A reverse osmosis system is a water purification system. It has a unique technology in which the water passes through a semi-permeable membrane. This membrane traps all contaminants and pollutants that there floating around in the water. The RO system is so potent that it even removes dissolved pollutants from the water.
These types of water filtration systems can remove microscopic contaminants from the water. They can remove particles as small as molecules, ions, and even some types of bacteria that are lethal for human health. Because RO water filtration systems are so potent and effective, they are used in the industrial production of potable water.
The RO process also can remove salt from salt water and give you fresh and clean drinking water. RO water filters are used to recycle water, for treating wastewater and even produce energy.
The Science Behind Reverse Osmosis Filtration System
To understand how a RO system works, it is essential to understand the concept of Osmosis. Osmosis is a natural process that occurs in nature. In this process, less concentrated fluids flow towards the higher concentrated fluids through a semi-permeable membrane. For example, freshwater will flow towards the saline solution when kept in a container separated by a semi-permeable membrane.
Reverse Osmosis is a similar process but only in reverse. This means the higher concentrated fluids flow towards, the lesser concentrated fluids with the application of an external force. As the stronger fluid moves towards the lesser concentrated fluid, the semi-permeable membrane traps all the contaminants, thereby filtering the water.
Things to Consider When Buying a Reverse Osmosis Water Filter
Before you buy the best reverse osmosis water filter, it may help you consider a few things. Considering these things will help you make the right choice and be happy with your purchase in the long run.
The first and most important thing to consider while buying a RO system is the space it will require. A RO water filter is not a small piece of equipment. It requires quite a bit of space. Not only will you require space for the RO system’s pre-filters and other components but also for the RO tank. So make sure you have enough space for the whole system to fit and work perfectly.
Another critical thing to consider while buying a RO system is the water pressure at your house. Most RO systems need a water pressure of at least 40 PSI. With a PSI below 40, the RO system will most likely not work. Some RO water filters come with an in-built booster pump, while others do not come with a booster pump. It is important to note that if the water pressure does not increase even with a booster pump, the RO system most likely won’t work for your household.
Another significant point to consider while buying a RO system is your water usage and the quantity of water you can access. While RO systems are very effective in filtering water, they also waste large amounts of water. Often the contaminated water is way more than the quantity of water you receive after the filtration process. In simple terms, RO systems create more wastewater than filtered water.
If you do not have an abundance of water and cannot afford to create wastewater, RO water filters may not be for you.
If you live in a city, you most likely receive your water supply from the municipal water system. If you live in a suburban area or a rural area, you most likely own a well, and the well is your primary source of water. When buying a RO water filter, carefully check the description as some RO filters are more equipped to filter well water than others.
The best thing about reverse osmosis water filters is that they are extremely good at filtering water. They remove almost all contaminants from the water. But as they remove all the pollutants, they also remove many essential minerals from the water. And water without these essential elements is not so beneficial for human health. So, when you buy a RO system, ensure that it has an alkaline re-mineralizer filter that puts back the beneficial minerals into the water.
Reverse osmosis filtration systems are generally easy to maintain. They do not require a lot of work to maintain and clean. Once in a while, you will need to check the filters and replace them if needed. RO systems have more than one filter. And sometimes, you might need to change a filter once its potency is reduced. It’s important that you keep track of every filter you change to know which one you need to change next. This also adds to the extra cost, but the good news is that it is not very often.

FAQs for the Best Reverse Osmosis Water Filter
What Contaminants Do RO Systems Remove?
Water is an essential element vital for human survival. And what’s even more important is clean and fresh water. RO systems have an important task to purify the water and remove contaminants from it that aren’t beneficial. A reverse osmosis system has many filters. Each filter is responsible for eliminating specific pollutants and contaminants.
RO systems remove lead, dirt, sand, copper, fluoride, magnesium, and many other pollutants from the water.
Are There Any Risks To My Health With The RO System?
RO systems have the crucial task of removing contaminants from the water and keeping us safe and healthy. And so, instead of harming us, reverse osmosis filtration systems actually have many health benefits. Image drinking water that is contaminated with bacteria and pollutants. You would surely fall sick. And a quality RO system saves you from all the medical bills.
But it is important to note that while they remove most contaminants from the water, they also remove beneficial minerals like calcium and magnesium. It is vital for human beings to receive these minerals from the water to stay healthy. They are essential for our bone health and much more. So, the benefits and risks of using a RO system are still under debate. However, there are no real health risks involved when using a quality RO water filter. In fact, it has many health benefits.
How Does The RO Water Filtration System Affect The Environment?
The only problem with RO systems is that they waste a lot of water. For every 2 gallons of filtered water, they produce 8 gallons of wastewater. You can, however, use this wastewater for other purposes. While this system does produce a lot of wastewater, it also prevents thousands of people from buying plastic bottled water, thus saving the environment from a lot of toxic plastic.
How Long Does A RO System Last?
A reverse osmosis system lasts for many years as long as you maintain it well. Just like anything, these systems, too, need maintenance from time-to-time. Make sure to change the filters when it is required, and you are good to go.
Is A Water Distiller Similar To A RO System?
A water distiller and a RO system use different types of devices and different processes. But the end result in both of them is the same – filtered clean water. The RO system uses a semi-permeable membrane and various filters to trap the contaminants in them. And a water distiller boils the water and then uses the condensed steam to purify the water. However, both of these water filtration systems benefit from a quality carbon filter.
Whether you live in the city or in a rural area, having a high-quality reverse osmosis water filtration system can benefit you. If you desire clean and fresh drinking water, give a reverse osmosis water filter a try. These filtration systems are some of the best and do an excellent job at removing purities from the water.
They remove 99 per cent of contaminants from the water. Yes, it may cost a bit more initially when you setting it up and changing filters. But we believe the few extra dollars you pay are worth the clean water you receive in return. We hope that the list we have provided you with above can help you choose the best reverse osmosis water filter and have access to clean, safe water.
