Is Whole House RO System A Good Choice?
Reverse osmosis – which is what the “RO” in the title of our article stands for – is rapidly gaining followers around the world, and for good reasons. However, since it came to popularity, there have been a lot of myths and fake news about it. There are still people who believe that reverse osmosis for the whole house is in fact unhealthy. In this article, we’ll explain the ins and outs about whole house reverse osmosis, so that you can make up your mind about whether it’s your cup of tea (or water, in this case) or not.
What Is Whole House Reverse Osmosis System?
For years now, whole house reverse osmosis systems have been one of the most frequently chosen filtering solutions. The reason for that? First of all, whole house RO systems come in many variants, shapes and sizes. You do not have to worry about finding a whole house reverse osmosis for your needs – they are specially prepared to be installable in any house.
However, that’s not the real reason for which reverse osmosis systems are such popular. Their efficiency and effectiveness is the most important cause – they remove approximately 90-98% of pollutants from tap water, providing you with pure, healthy and clean water. Because the filters of whole house reverse osmosis systems whole house reverse osmosis system are so accurate, they are able to remove even bacteria and viruses!
Still, over the years, many myths and reservations arose around whole house RO systems. In this article, we’ll try to tackle most, if not all of them. From here you will learn, among others, how reverse osmosis works!
What Affects The Way Water Tastes?
Before we get to discussing whole house RO systems themselves, it’s good to cover some basics (trust us, this is pretty important).
First, we need to take a look at tap water. Where does it really come from? For most houses, it comes from waterworks, though many houses do have their own intakes. Regardless of which option it is for your house – one thing doesn’t change. Each water has a slightly different composition and different concentrations of particular substances. Another thing to remember is that we never deal with pure H2O – there are ALWAYS other chemicals involved. They affect the way water tastes, but also just how healthy it really is for us.
So, a simple conclusion – if it contains harmful substances, it’s going to be dangerous to drink such water (hence the need for whole house reverse osmosis systems). But you don’t need to worry about this that much, as waterworks usually have very good standards (they are controlled by many institutions, both governmental and non-governmental ones), and if not pure, this water should normally be fairly harmless. Still, the taste of your tap water will vary from place to place, from waterworks to waterworks… even the state of your pipes affects it!
However, there are some potential issues with tap water from waterworks – the main one being chlorine, used for disinfection. It gets even more complicated in the case of private intakes, which can be contaminated by a larger number of sources. So, what choices do we have to make our drinking water safe and pure?
Whole House Reverse Osmosis – Facts and Myths
Many people are still uncertain if water after reverse osmosis is good for their health. Some people claim that the water produced this way is downright dangerous. What’s the truth about water from whole house reverse osmosis?
Does whole house reverse osmosis system use more water?
The answer is – YES. This one is true, but it isn’t as bad as it sounds. First, some numbers – reverse osmosis systems normally need between 4 and 7 litres of water to produce 1 litre of “pure” water, filtrated through the osmotic membrane. This is actually how reverse osmosis systems work – they put water through a special membrane which filters it, removing every impurity. However, you need to keep in mind that in new whole house RO systems, these numbers are much lower – only around 2 to 2.5 litres of water is needed to produce 1 litre of reverse osmotic water.
Also, there is one additional factor to take into consideration. That water does not necessarily have to go to waste. Water which was “dropped” in whole house reverse osmosis can serve another purpose – it can be used for watering garden, flush the toilet, wash dishes… anything, really – and nowadays, systems allow for such efficient use of water. Therefore, if you work around it, you do not have to waste much water at all!
Is water from whole house reverse osmosis sterile?
Again – YES. Water which comes from the whole house RO system is, in fact, sterile – there is nearly nothing inside of it, except for “near-pure H2O”. Many people have reservations about this. They consider water without minerals to be “incomplete”. However, again, there is more to be considered. First of all, some of the minerals contained in water aren’t even absorbed by the human organism. Some of them are downright harmful, which we’ve already talked about. And then, finally, minerals from water make for a small fracture of minerals our organism absorbs (much more gets absorbed from food).
Plus, there are ways to accommodate the needs of people who would like their water to be enhanced with minerals after it was filtered with a whole house reverse osmosis system. In modern reverse osmosis systems for the house, it is possible to install special revitalizing cartridges, which enhance water with minerals. They can even regulate its pH indicator and redox potential. Thanks to this, the reverse osmosis system becomes a perfect source of alkaline water!
Is a whole house reverse osmosis system expensive?
Another myth – whole house RO systems used to be considered to be a fancy, expensive addition. But not anymore! Today, everyone can enjoy whole house reverse osmosis. Installation is really simple (actually, some types you can install on your own, without the help of a professional assistant). Most RO systems are compact and easy-to-install devices that do not disturb the interior of your kitchen. The best producers on the market offer customers with full assembly kits, together with an elegant spout and a practical frame that helps the user maintain order among the wires.
Forget about big, noisy machinery of the past – today, whole house RO systems can be elegant and discreet (of course, that depends on the type and your needs – higher output DOES sometimes call for a bigger frame).
Benefits of Whole House Reverse Osmosis
Okay, having covered the myths, it’s time to move onto the benefits of having a whole house reverse osmosis system. Water from a whole house RO system is perfect for:
- Saving money on water – especially those of you who can never have enough of bottled water will fall in love with their whole house reverse osmosis system. You won’t have to ever again spend a fortune on bottled water – you’ll have a steady supply of even better drinking water!
- Babies – as toddlers and kids do not have the same mineral requirements as adults, water which is deprived of minerals and “neutral” is just perfect for them. Water after reverse osmosis is the best water there is for making baby food.
- Cleaning – be it clothes, dishes, or anything else in your house – water from the reverse osmosis system is “neutral” – which means, if you previously had problems with “hard water”, which generates mineral deposits, your water is now safe to be used – as there are no minerals inside to create the residue!
- Home appliances – the aforementioned mineral residue is what damages your dishwasher and washing machine. Water created by the whole house RO system does not generate scale build-up and mineral deposits, so won’t damage your appliances.
- Fish and plants – any life you would like to sustain in your house will appreciate the use of water generated by the whole house reverse osmosis system. This water is neutral, does not contain chlorine nor dangerous minerals, and is perfect for such purposes.
Downsides to Whole House RO Systems:
Of course, there are some downsides to installing a whole house RO system. We want you to make up your mind based on facts and not just enthusiasm. Here we go with the most notable problems people report:
- Space requirement – we did mention that these days, that’s becoming less of a problem, but that doesn’t mean whole house RO systems take no space AT ALL. Of course, they require some space to be installed.
- Money cost – depending on the type, whole house reverse osmosis systems vary from fairly inexpensive to quite pricey. But yes, indeed, they are an additional expense. The choice is yours to make if it is worth it, in the end.
- Further costs down the road – as previously mentioned, the whole house reverse osmosis system does use up more water than would be the case without it, by just using tap water. However, we’ve also provided you with ideas on how to minimise these losses.
Okay, that’s it for today. Now you’ve got the basics of the whole house reverse osmosis systems – we hope these will help you make up your mind whether you’d like to invest in this filtering solution. If you’d like to learn more, check the rest of our articles!
Aqua control system provides like a magazine the most up-to-date drinking water purification methods and technologies.
Water treatment – the process of bringing contaminated water to the cleanliness state required for a given application. The composition of elementary water treatment processes is selected according to the final product. The main methods of that represent products on our website aqua control system.
Water pollution – adverse changes in the physical, chemical and bacteriological properties of water, caused by the introduction of excess inorganic substances (solid, liquid, gas), organic, radioactive or finally heat, which limit or prevent the use of water for drinking and economic purposes.
Composition of polluted waters
Water pollution is mainly caused by chemicals, bacteria and other microorganisms that are present in increased amounts of natural waters. Chemical, organic and inorganic (mineral) substances come in the form of solutions, colloidal solutions and suspensions. The chemical composition of pollutants is shaped by natural factors, e.g. the decomposition of substances from soils and rocks, the development and death of aquatic organisms, and anthropogenic factors. The most common anthropogenic surface water pollutants include pesticides, surfactants, petroleum hydrocarbons, phenols, chlorine biphenyl derivatives and heavy metals: lead (Pb), copper (Cu), chromium (Cr), cadmium (Cd), mercury (Hg) and zinc (Zn), as well as heated waters (thermal pollution), which are particularly dangerous for surface water with low flow or standing water. Most anthropogenic water pollutants are toxic to aquatic organisms. Very persistent pollutants in the aquatic environment and very difficult to undergo chemical and biochemical processes are called refractive substances.
The most pollutants end up in water together with sewage. Aqua control system show other sources of water pollution are water and land transport, the use of pesticides and fertilizers, as well as municipal and industrial waste. Waters also become polluted as a result of eutrophication. The water cycle in nature has been disturbed by man – deforestation, agriculture monoculture, improper and excessive farming, urbanization.
Division of impurities Because of its origin
natural – those that come from admixtures contained in surface and underground waters – e.g. salinity, pollution with iron compounds;
artificial – otherwise anthropogenic, i.e. related to human activity – e.g. from sewage, runoff from agricultural areas, municipal landfills. Artificial impurities can also be divided into biological (bacteria, viruses, fungi, algae) and chemical groups (oils, gasoline, greases, oil, fertilizers, pesticides, acids, alkalis).
Due to the degree of harmfulness
directly harmful – phenols (gas works, coking plants), hydrocyanic acid (gas works), sulfuric acid and sulfates, acid rain (fertilizer factories, pulp mills, artificial fiber factories),
indirectly harmful – those that lead to a reduction in the amount of oxygen in the water below the level necessary to keep aquatic organisms alive.
Due to the durability of impurities
decomposable – containing organic substances, potentially toxic, but subject to chemical transformations into simple inorganic compounds with the participation of bacteria (domestic sewage)
non-decomposable – containing substances that do not undergo major chemical changes and are not attacked by microorganisms (salts of heavy metals)
persistent – containing substances that are slightly biodegradable and remaining in the environment in a stable form for a long period (pesticides, phenols, petroleum distillation products)
Because of the source
point sources – sewage discharged in an organized way through sewage systems, mainly from industrial plants and urban agglomerations,
surface or area pollution – pollution washed off by atmospheric precipitation from urbanized areas without sewage systems and from agricultural and forest areas,
pollution from linear or banded sources – pollution of transport origin, produced by means of transport and flushed from the surface of roads or peat bogs, as well as from pipelines, gas pipelines, sewage and sewage channels.
