Reverse Osmosis Purifier Vs. Ionization – Which One is Better?

We are all quite familiar with the type of water supply systems around us, be it private or public.

It needs some additional treatment ensuring a standard water quality for drinking and other purposes too.

Here we will mostly deal with the difference between Reverses Osmosis Purifiers and Ionization (ion exchange method).

IONIZATION

It’s a process that ensures the removal of inorganic compounds, this softening hard water. Here, how sodium ion (Na+) are exchanged for every magnesium ion (Mg2+) or calcium ion (Ca2+) using resin beads. The product formed reacts again with NaCl regenerating the resin. It does not guarantee to remove the bacteria or particles. But this method increases the pH value of water helping in the separation of acidic and alkaline components.

REVERSE OSMOSIS

Osmosis refers to the transfer of solvent molecules from low concentration to high concentration through a semi-permeable membrane. Reverse Osmosis is just the opposite of it. Solvent molecules move from high level to low level through the semi-permeable membrane but under an external pressure higher than the osmotic pressure.

DIFFERENCES

  1.    Economic method

Reverse osmosis requires the application of external pressure. The equipment used for this works on electricity ensuring removal of foreign particles around 90 to 99%.

Resin Beads, on the other hand, gets regenerated and also balances the acidic and alkaline components. This makes ionization a good option if one looks at the situation economically.

  1.    Mineral removal

Healthy water is not directly proportional to the level of filtration. RO water purifier filters out every microparticle, making the solid count almost zero. This also means that water is left dead. The mineral content of water also falls to zero. Consumption of demineralized water leads to different deficiencies and dilution if your mineral intake is not sufficient.

On the other hand, Ionization enhances the mineral content of drinking water. It involves the addition of electrolytes which enable a better hydration capacity. This can act as a mineral supplement in your daily diet, filling the requirements of your body. Also, water is in liquid form, so mineral absorption is quicker if compared with food intake. Thus ionized water is a great way to maintain your body’s electrolyte and mineral balance.

  1.    Space requirement

RO systems consist of large units taking a lot of kitchen space, but water ionizers consume very less space as compared to RO systems. It generally comes in the form of the small jug so it can fit in your refrigerator.

  1.    The quantity of water involved

A lot of water is wasted in the RO system. Due to a high-pressure requirement, a large amount of water is being pumped through the system causing a lot of waste generation which consists of the dissolved particles along with a large amount of water. There are technologies which claim to have reduced this wastage to 0%, but they are costly enough to choose an alternate path.

Water ionizers, on the other hand, not only add minerals to the water but also has zero wastewater generation which again makes it a better choice over the RO system.

  1.    pH value

RO systems remove all the solid particles making water acidic for consumption. While ionization ensures a healthy and balanced pH.

Water purifiers these days have combined RO and Ionization in an economical way making it a non-zero sum game.
