Reverse osmosis (and other similar filtration processes) help to remove contaminants from water. They remove truly harmful things: including bacteria, chemicals, and heavy metals.
Unfortunately, they also end up removing useful minerals (like calcium and magnesium) from water.
In other words, they end up demineralizing water. We see a similar thing, albeit to a less degree, in desalination plants. They remove the ‘salt’ from the water.
But in the process, they also end up removing other desirable things like calcium and magnesium from the water. Hence the need to remineralize reverse osmosis water.
The water from which such minerals are stripped ends up with a rather low PH. It, therefore, ends up becoming a bit acidic. It can, as such, cause corrosion in the water distribution system.
But the bigger concern is with regard to the effect of such water on the human body.
Why You Should Remineralize Reverse Osmosis Water
Calcium and magnesium are among the most important minerals in our bodies. Drinking water from which they have been stripped may have adverse effects on the body.
Granted, most of our intake of those minerals is supposed to come from our food, rather than from the water.
But another complication arises: because using demineralized water to cook food may cause the said minerals to leach.
Thus, when we drink such water, we miss out on the calcium/magnesium we would have gotten from “natural” water. And when we use such water to cook, it causes the minerals in our food to leach.
So it becomes clear that using such water to drink and cook can, over time, cause serious deficiencies.
Further, the water that lacks the minerals in question has a ‘strange’ taste… Most people describe the water’s taste as “flat” and “unrefreshing”.
A question arises, as to if anything can be done about these issues. And thankfully, the answer is “yes”. There is one thing we can do, to address the issues that arise as a result of water demineralization.
What can be done is to restore the lost minerals to the water. But that has to be done while ensuring that the contaminants that were removed don’t find their way back. That is possible through a process we refer to as remineralization.
In the course of that process, the minerals that were lost are restored to the water. Only the minerals are restored: the contaminants that were removed are kept away from the water.
Water Remineralization Objectives
The main goal in remineralizing water is to restore the minerals that were lost. These may be those that were lost during reverse osmosis (or whichever other filtration process the water was subjected to).
They may also be those that were lost during desalination.
The latter aspect is important if you live at a place where your water supply comes from a desalination plant.
Desalination always leads to the loss of certain minerals from the water. Yet there are certain areas where the only water that is available comes from desalination plants.
The minerals in question (which we aim to restore) are mainly calcium and magnesium. But there are others, whose traces may also have been lost.
Those include the likes of sodium, iron, copper, manganese, selenium, and so on. In some cases, attempts are also made to restore those as well.
Upon restoring the minerals, the water becomes more beneficial to the body.
Steps to Take
- Firstly, the person consuming the water gets the minerals directly.
- Secondly, the risk of the water causing mineral leaching (when used for cooking) is done away with.
- Thirdly, the potential injury to the intestines’ mucous membranes that are associated with demineralized water usage is done away with.
At another level, once the minerals are restored to the water, the taste tends to improve. As note earlier, water that has lost the said minerals tends to have a “strange” taste. Upon restoring them, the water regains the ‘natural’ taste.
At yet another level, upon restoring the minerals, the water’s PH goes up. It becomes less acidic.
It is, therefore, less prone to causing corrosion to the water distribution system.
More critically, the water becomes more alkaline. It is, therefore, less prone to causing the harms that are may come with the use of ‘acidic’ water. Conversely, the person taking such water gets a chance to tap into the benefits that come with alkaline water use.
Water Remineralization Options
There are several ways in which you can go about restoring minerals to the water. These include the use of a mineral filter, through the use of an alkaline pitcher, and through green blends.
Others include the use of tablets and powders as well as Himalayan salts. We will now venture to examine what each of these methods entails.
How To Remineralize RO Water Using a Mineral Filter
Water usually loses minerals in the Reverse Osmosis (RO) filtration system. Therefore one of the best ways to restore them is by adding a mineral filter.
That is by adding a mineral filter to the RO system. The end result is a situation where the water would be regaining the lost minerals immediately. It would be regaining them before it leaves the RO filtration system.
Here are the steps to follow, if you want to restore minerals to your water using a mineral filter:
- Acquire a mineral filter that is compatible with your RO system. Sometimes, the vendor of your RO system may be selling these sorts of filters. So you can buy the filter from your system’s vendor and have a compatibility guarantee. If your system’s vendor doesn’t sell such filters, you would have to buy them from third-party vendors. Just ensure that what you buy works with your system: otherwise it won’t be of much help to you.
- Thread the filter to the RO system. (Before doing this, you will need to have shut down the water and released pressure). Examine the filter and the RO system’s “hooks” properly. Ensure that you thread the right end of the filter to the right “hook” in the RO system. Because the threads may be delicate, be careful while threading the filter in.
- Secure the mineral filter onto place using clips (if those are available). In most cases, the clips attach to the membranes, at very specific positions. Just ensure that you end up with a tight bond. The bond you end up with shouldn’t allow for leakages – even at high pressure.
- Restore the water supply.
Just remember that the mineral filter will tend to lose its potency with time. You, therefore, need to know when that happens and ensure that you replace it in good time.
Things To Know
It is also important to understand the extent to which the mineral filter actually restores the minerals. Some of these filters restore them at a rate that is too low.
It is important to understand what the acceptable levels of various minerals (calcium, magnesium, and so on) in water are.
Then ensure that the filter you use is capable of restoring them to such levels. You may consider testing the water, to be sure of what you are getting.
So you can test the water for the calcium and magnesium levels in it. You can also test the water for its PH level.
Just try to be sure that the filter is giving you the right results before you continue using it.
It is worth mentioning that there are some RO filtration systems that come ready-made with mineral filters.
Instead of referring to them as ‘mineral filters’, the vendors may refer to them as ‘alkalization filters’.
If you find one such RO system, there would be a slight advantage. You wouldn’t have to go through the process of installing a mineral filter manually. But you would still be needing to replace the filter cartridges as the need arises.
How To Remineralize Water Using an Alkaline Pitcher
An alkaline pitcher contains a filter at the top, which restores minerals to the water in it. It is a low-cost yet quite effective way to restore lost minerals to the water.
It helps too that this, being a pitcher, is also highly portable.
Thus, for instance, you can take it with you when going camping. Or you can travel with it if you are going to a place where you will need to filter water. (That is, a place where you will need to filter water, then restore minerals to it).
If you want to restore minerals to water using an alkaline pitcher, these are the steps to follow:
- Acquire a suitable pitcher. Before buying any pitcher, make inquiries on the results it is capable of delivering. Try to understand the extent to which it can restore the minerals to the water. Also, try to understand the extent to which it can raise water’s PH. Further, make inquiries on the pitcher’s filter life, and how easy it is to replace its filter. You may also want to establish how easy it is to acquire the pitcher’s filters, and what they cost.
- Ensure that the filter in the pitcher still has potency. Some of these pitchers have indicators, through which you can easily tell how much filter life is left in it. With others, you have to check manually. Either way, ensure that the filter in the pitcher still has potency.
- Pour water into the pitcher. The water will undergo reverse osmosis remineralization as soon as it gets into the pitcher/as soon as it goes through the filter.
- Use the water as per your needs.
The key thing is to remember that the pitcher’s capability depends on its filter’s potency. Therefore once the filter loses its potency, the pitcher loses its power to restore minerals to the water. That being the case, you need to ensure that you replace the filter’s cartridges as soon as the need arises.
How To Remineralize Water Using Green Blends
If you prefer a ‘natural/organic’ approach to restoring the lost minerals to your reverse osmosis water, consider green blends. These are made using plant extracts.
Those are plant extracts that are known to be rich in the minerals we want to restore to the water.
Some people may have doubts about this approach to restoring the minerals. But there are others who swear by it.
If you want to restore minerals to water using green blends, follow these steps:
- Acquire a green blend with a proven ability to restore minerals to the water. You can purchase the green blend online. Or you may be able to find it at a local store that deals in these types of wares. Just ensure that the blend you buy has genuine potency.
- Read through the green blend’s usage instructions, to understand how much you need to apply. While at it, try to understand how the blend works. You will then be in a position to know whether or not it makes sense.
- Measure the right quantity of the green blend for the amount of water you wish to treat. Remember, if you apply too little of the blend, you may not get proper results. On the other hand, if you apply too much of the blend, you may end up with undesirable results. In any event, applying too much would amount to wastage. So just apply the right amount of the blend for the amount of water you wish to restore minerals too.
- After applying the green blend to the water, allow enough time for the restoration of the mineral to take place.
- Proceed to use the water as per your needs. This may be in terms of drinking, cooking, watering your animals… and so on.
After choosing to use a green blend, you won’t have to worry about filter issues. But you will need to ensure that you always have enough of the green blend around.
Further, you may need to get used to the taste that the green blend may introduce into the water.
How To Remineralize Water Using Tablets
The tablets in question here typically contain mineral blends, which help to remineralize RO water.
So you simply add them to the water, in order to restore the minerals. Some of them have good efficacy. They are also easy to use: unlike the filters that are sometimes hard to install and replace.
The challenge is typically in finding tablets that actually deliver proper results.
If you want to restore minerals to water using tablets, follow these steps:
- Find electrolyte/mineral blend tablets with good capabilities. Undertake some research first, to identify the electrolyte/mineral blend tablets that actually work. Then ensure that you only buy those.
- Read through the tablets’ usage instructions carefully, to understand how they work. It is also at this point that you will know how many of the tablets you need to apply.
- Drop the right number of tablets into the water you wish to restore minerals too. Typically, you will need to have put the water into some sort of container. So it is into the container that you drop the right number of the tablets.
- Allow the tablets enough time to work. Most of them work almost instantly. But there are others where you need to wait for several minutes. Just ensure that you are patient enough.
- Proceed to use the water as per your needs. This may be for purposes of drinking, cooking, watering your animals… and so on.
After starting to use the tablets, you may consider subjecting the water to some testing. You would be doing this to understand the extent to which they are actually working.
So you test the water before applying the tablets, to see its calcium, magnesium, and PH levels.
Then you test the same things after applying the tablets, to see how well they work. You can at least do this the first time you use them. Then you can make a better decision on whether or not to continue using that particular brand of tablets.
How To Remineralize Water Using Powders
Like the tablets, the powders in question here typically contain mineral blends. They are, in other words, electrolyte blends. They provide a simple way to restore minerals to the water.
These are the steps for you to follow if you wish to restore minerals to water using powders:
- Acquire an electrolyte/mineral blend powder with proper efficacy.
- Read the powder’s usage instructions carefully, to understand the right way to use it.
- Measure the right amount of the powder for the quantity of water you want to restore minerals to.
- Mix the powder with the water, as per the usage instructions.
- Allow enough time for the powder to actually restore minerals to the water.
- Go ahead and use the water as per your needs.
Having made the decision to be treating your water using these powders, keep a couple of things in mind. First of all, ensure that you always have the powder in question available.
In other words, ensure that it never runs out. Secondly, remember to be applying it to all water before usage.
You may also consider subjecting the water to which you apply the powder to some testing. You would be doing this with the goal of understanding the water’s chemical composition.
Only then can you see the extent to which the powder is working. This is the sort of thing where objective tests can be very useful.
How To Remineralize Water Using Himalayan salts
Himalayan salt contains pretty much all the minerals that we need to restore. It is cheap and easy to use.
The only challenge you may encounter is in working out how much of it you need to use.
That is, how much you need to use to get the result you need. Another challenge you may encounter is in finding genuine Himalayan salt. It also needs to be finely ground: otherwise, it could affect your water’s taste.
After making the decision to restore minerals to water using Himalayan salt, these are the steps to follow:
- Acquire genuine, finely ground Himalayan salt.
- Measure an adequate amount of salt for the amount of water you wish to treat.
- Pour the salt into the water.
- Allow some little time for the salt to work.
- Go ahead and use the water as per your needs.
The key to note here is that we are making reference to Himalayan salt. So this is not about ordinary table salt. Ordinary table salt is unsuitable for this purpose on two accounts.
Firstly, it only contains sodium and chloride (sometimes with little iodine). Therefore it is not capable of restoring the required minerals – the likes of magnesium, calcium, and so on.
Furthermore, if you were to add table salt to your water, it would tend to affect its taste.
Further still, it is common knowledge that consuming too much table salt could cause health problems. The upshot is that you need to ensure that what you are using is Himalayan salt: not ordinary table salt.
You don’t have to make a choice between consuming contaminated water or putting water through filtration and losing essential minerals.
It is possible to have water that has undergone thorough filtration (including reverse osmosis) and which still has all minerals. That is possible through ro remineralization.
From the water remineralization methods we have explored above, you can find one that is ideal for your needs. Suppose you want a method that restores the minerals “at source” (as soon as they are lost).
In that case, you can consider buying a mineral filter and adding it to your RO system.
Or you can buy one of those modern RO remineralization systems that come ready-made with a remineralization/alkalinization filter.
If you want a portable system through which you can restore the minerals to water, consider an alkaline pitcher.
If you want a natural/organic system for restoring the minerals to your water, consider using a green blend.
And if you want an easy-to-use or very cost-effective approach to restoring the minerals, consider using an electrolyte tablet. Or consider using an electrolyte powder.
Whatever the nature of your water remineralization needs, there is a method you can use to get good results.
