How to Use a Water Ionizer With Reverse Osmosis

Posted by Alkaline Water Plus on

Water Ionizers and Reverse Osmosis [RO]

A water ionizer will work with reverse osmosis, RO, but you will need to understand a few things about water ionizers & RO in order to make it work.

When you hook a water ionizer up to a source that has no or few minerals [such as an RO unit] you are then going to have to make sure you are always providing enough minerals.

Re-Mineralization is the Key to Good Ionization with Reverse Osmosis Water

Using a water ionizer without the right amount of minerals will affect the range of pH you’ll be able to get. The higher pH you want, the more minerals you’ll need to add. For this reason you should probably have several remineralizers on hand.

How do You Install a Re-Mineralizer into the Reverse Osmosis System Set-up?

The way to do that is to cut the line between the membrane and the automatic shut-off valve, so that you can insert it where the slowest flow-rate of RO water will be [to get the maximum amount of minerals possible]. Here is a detailed diagram of where you would place it:

Where you see the single “Remineralizer” in the diagram, I usually suggest to put 2 or three remineralizers there. The reason is that RO water is so void of minerals it will benefit from the longer duration of sitting in a bed of minerals to give it enough time to pick up the needed minerals.  Once your water has dissolved a sufficient amount of minerals it won’t continue to dissolve them, so it won’t overload your water with minerals by doing this.

How Long will a Remineralizer Last?

It depends on your source water as to how many gallons will be re-mineralized properly. If you’re using a reverse osmosis system, then one remineralizer should last about a thousand gallons [same as the water ionizer filter], but three remineralizers [as suggested in the paragraph above, are likely to last a year or two.

You should periodically test the pH of your ionized water and replace [or add to] the in-line remineralizers if need-be.

Periodically Test Your Ionized Water

Anyone using RO should periodically test their ionized water [every month or so]. If the pH starts dropping during that time, I suggest that you add in another remineralizer. You don’t necessarily have to remove the old one if you think there are still minerals in it, but after two years it would very likely be used up. I suggest that you write the date on each remineralizer that you install to keep track of it.

Which is Better: Letting the Water Ionizer Filter Water for You or Filtering with Reverse Osmosis Remineralized Water?

It is sometimes necessary to use water ionizer with reverse osmosis. For instance, if your water is way too hard [over 300 ppm of calcium hardness], or if you are using a sodium/potassium exchange water softener you would need use reverse osmosis to remove the dissolved calcium, sodium or potassium [which before RO used to be impossible to filter].

However, if you don’t HAVE TO use reverse osmosis, I suggest not to, but the choice is completely yours. Sometimes using RO gives you better filtration at less cost, so there is that, but it wastes water and isn’t particularly for beginners. The use of the water ionizer’s filters are very effective in removing chemicals and toxins. If you have difficult water, there are prefilter systems that are designed and can even be customized for your water to work in many cases even better than reverse osmosis. In this case you are invited to take us up on our free water-test/analysis offer.

What Kind of Remineralizer Filter is Best?

It’s best to use an in-line remin filter, or a few, when you have a water ionizer with reverse osmosis, so that it forces the water to go from one end to the other of a longer distance before re-entering the system. It’s also best to use a blend of calcium and carbon. I prefer to use calcite and coconut-shell carbon for the best results. The reason this works better than straight calcium is that the carbon keeps the calcium from fusing together and so keeps the surface area for remineralization the highest possible.
