What Is Reverse Osmosis Water and How Does It Work?

Reverse osmosis water (RO) is a multi stage filtration system used to remove contaminants and other harmful chemicals from the water. However, since the RO filtration process is very efficient, it also removes mineral content from the water.

Overall, the RO system is great at making drinking water from dirty or contaminated water, but it also removes several good things from the water that are beneficial to our health.

Because of this, RO water is often remineralized to add back many of the minerals removed, turning it from regular drinking water into healthy water.

The Production and Treatment Process of Reverse Osmosis

Purified Water - How it Works

The RO purification process involves running water across a filtration process to get purified water. The process requires high pressure to push the water through a semipermeable membrane to remove contaminants, harmful chemicals, and bacteria.

When the water goes through the permeable membrane by applying pressure, it removes viruses, bacteria, and chemicals with high efficiency. The membrane efficiently removes toxic chemicals and reduces the total dissolved solids in the water, improving taste and smell.

The purification process results in contaminant-free water, which many brands of bottled water then use to add minerals to make their brand unique.

Since RO purified water removes dissolved solids from the water, it’s important to add some minerals back into the RO water to improve the water quality after the water purification process.

There are many different ways to get the most out of your own water by using different remineralization methods. Here are a few:

  • Mineral Drops

  • Himalayan Salt

  • Alkaline Water Filter Pitcher

  • Mineral Stones

  • Trace Mineral Drops

  • Mineral Cartridge

Any of these methods can turn regular bottled water into healthy water. They’re all great ways to improve RO water.

Additionally, you can easily add mineral stones, mineral drops, or Himalayan salt to one gallon of water to have a huge supply of mineralized water at your disposal.

Benefits of Drinking Reverse Osmosis Bottled Water

Even though the reverse osmosis purification process removes many minerals and beneficial things from the water, RO water still offers many benefits on its own.

Improved Taste

The reverse osmosis filtration system removes bacteria, viruses, and chemicals from the water. These contaminants negatively impact the water’s good taste and odor.

RO purified water offers a better taste than unfiltered or tap water, while also being safer to drink.

Healthier Option

Because reverse osmosis removes all contaminants from the water, it significantly improves your safety when drinking water.

It allows anyone to stay hydrated by drinking water from a safer and healthier source.

Better for Cooking

RO purified water can add a refreshing taste and great smell to your food.

A good reverse osmosis filtration system also allows you to use tap water to cook, speeding up the cooking process with higher volumes of water than a regular filter.

Environmental Friendliness

Using a filtration process like reverse osmosis is an environmentally friendly way to get purified water.

You can either have a filter installed under your sink to use tap water or use refillable water bottles instead of plastic bottles to reduce waste.

Does All Bottled Water Use Reverse Osmosis?

Not every bottled water can be called reverse osmosis bottled water. There are many different types of bottled water, like:

  • Spring water

  • Mineral water

  • Purified water

  • Distilled water

These different bottled water types can significantly vary depending on their source. For instance, spring water is naturally pure, requiring little to no filtration before you can drink it. There are also many different purification processes other than reverse osmosis, like ozonation, distillation, or micron filtration.

Reverse Osmosis vs. Spring Water

Spring water is naturally filtered by running underground across the earth’s surface. It often requires little to no treatment since the underground can remove more impurities than many purification methods.

However, reverse osmosis is a process that purifies dirty or contaminated water. It’s a treatment process to use on dirty or contaminated water, unlike spring water, which is already purified water.

Additionally, reverse osmosis removes many minerals and other healthy things from the water. Meanwhile, spring water is naturally infused with many minerals and other things that improve our health.

Reverse Osmosis vs. Mineral Water

Mineral water, much like spring water, also comes from underground sources running through caves and other systems. The water is naturally infused with many minerals, like calcium, magnesium, and potassium.

The purified water running underground also passes through many minerals that get infused into the water, with at least 250 parts per million (ppm) of dissolved minerals and trace elements. This is why the water has a unique and distinct refreshing taste.

In comparison, RO water is also purified, but the filtration process completely removes minerals from the water. So unless you remineralize RO water, using reverse osmosis to purify water from mineral deposits is counterproductive.

Reverse Osmosis vs. Distilled Water

Distilling water results in water similar to that produced by reverse osmosis.

The process of distillation involves heating up the water to its boiling point. Then, when the water evaporates, the steam is collected in another container, where condensation turns it back into water. Meanwhile, the solids and impurities are left behind since the steam won’t carry the solids.

As a result of distillation, the water has a higher quality and a higher purity level than RO water.

Reverse osmosis purified water results in similar purity levels but uses a semipermeable membrane to filter impurities and solids instead.

Reverse Osmosis vs. Tap Water

Tap water comes from a municipal water source, which is treated with many chemicals to remove impurities and neutralize toxins.

However, municipal water might still contain many undesirable solids and chemical traces of the products used to sterilize the water. In many cases, tap water lacks minerals, making it one of the worst and most inconsistent sources of water.

Many of the chemical traces remaining in the water also make it taste and smell bad. Because of this, tap water is often not the best option for drinking or cooking.

By combining reverse osmosis technology with tap water, we can remove whatever else is left from other contaminants that the chemicals couldn’t remove, as well as the chemicals left in the water. The resulting RO significantly improves tap water’s quality.

Reverse Osmosis vs. Alkaline Water

When the water is alkaline, it means it has a higher pH level than regular water from other sources. For water to be considered alkaline, it must have a pH level of 7.5 or higher.

Not all natural sources of water are equal. In places where acid rains are frequent, the natural pH of water can be considerably lower than average, resulting in acidic water instead of alkaline.

By using reverse osmosis, purified water can have its pH level lowered due to the removal of solids from the water. Although many impurities cause water to be less alkaline, reverse osmosis also removes minerals, which increase alkalinity.

Reverse Osmosis vs. Ozonated Water

Ozonated water uses a type of UV filtration system to create ozone gas from oxygen and then infuse it into the water to sterilize it. The process has a huge downside, which is its initial cost for expensive equipment.

The ozone sterilization is extremely efficient at killing viruses and bacteria present in water, but it doesn’t remove solids from it like the other methods. This means that ozonated water can keep a lot of its original minerals, but also other solids that bring impurities with them.

Ozonated water is a great option for sterilization of other things like fruits, vegetables, work surfaces, tools, and equipment. However, because it can contain other unwanted substances, it’s often not the best option for drinking water.

RO water, on the other hand, is great for drinking because the process removes solids and other things like viruses and bacteria.
