Does Reverse Osmosis Remove Sodium from Softened Water?

You may be concerned about the salt in your drinking water if you have high blood pressure or are at risk.

The typical American eats 3,436 mg of salt per day, significantly more than the US Department of Health and Human Services’ recommendation of 2,300 mg. cooking accounts for around 5% of your salt consumption.

Installing a sodium-removal water filter might help you reduce your salt intake.

Does Reverse Osmosis Remove Sodium from Softened water?

Yes. Installing a reverse osmosis drinking water network to work with your water softener is the complete approach to remove salt from soft water—along with a plethora of other impurities like chlorine and lead.


The pressure employed in the system must be greater than the osmotic pressure to drive water through the membrane. This is because the holes in the membrane are big enough for water molecules to get through but not large enough for sodium ions or many other pollutants.

On the other side of the membrane, freshwater has been stripped of the vast bulk of sodium.

Does Ozone Treatment Remove Sodium from Softened Water?

There are various alternative water treatment options available, with ozone water purification being one of the more intriguing. This procedure isn’t new; it’s been utilized for over a century in several parts of Europe and Asia.

Let’s look into ozone and see how it works like a water filter so you can make an educated decision.

Ozone disinfects water effectively and safely against a wide range of dangerous biological pollutants. In addition, because ozone immediately returns to its oxygen state after disinfection, no associated taste or odour is imparted to the drinking water.

Another significant benefit is that ozone water treatment does not require electricity, allowing water to be treated even during power outages.

There are two drawbacks to ozone use.

To begin with, by-products such as bromate and formaldehyde might be produced, which must be carefully monitored to avoid adverse health consequences.

Second, ozone is ineffective in removing minerals and dissolved salts thus, and it should be used in conjunction with other water treatment procedures.

By filling a compressed air chamber with UV light, an Ozone Generator creates O3. The resulting ozone is then transported through a diffuser, producing ozone-saturated bubbles.

Any organic molecules in the water are drawn to the third oxygen molecule in O3, oxidizing them. An ozone water purification system is usually combined with an activated carbon filter system to offer highly clean and pure drinking water.

How Does Reverse Osmosis Remove Sodium?


It’s easier to grasp reverse osmosis if you first understand osmosis. Osmosis is a natural process that occurs all around us and plays a crucial role in how our bodies work. Imagine two liquids on either side of a membrane to understand osmosis.

Different levels of dissolved material are present in certain liquids. Therefore, the dissolved material concentration on one side of the membrane is high. In contrast, the dissolved substance concentration on the opposite side of the membrane is low.

Osmosis is a process in which a liquid with a low concentration of dissolved chemicals flows over a membrane to a solution with a high concentration of dissolved substances. This flow will continue until there is an equal amount of liquid and dissolved material on both sides of the membrane. Osmotic pressure is the power that causes this flow.

The natural process of reverse osmosis is the polar opposite of this. Desalination is the omitting salt from saltwater and is a good example of reverse osmosis in action. When reverse osmosis is used to desalinate water, saltwater is pumped through a semipermeable membrane under high pressure.

What are the Filters to Remove Sodium From soft Water?

Although there are many different water filters and purification systems, only a few of them can eliminate sodium from drinking water.


Sodium and other pollutants, like arsenic, are not filtered by activated carbon filters, employed in carafe-style and faucet-mounted filters, which account for a large share of the retail filter market.

Knowing what impurities a filter removes can aid the user in selecting a filtering system that matches their needs.

Reverse Osmosis filter

These systems are piped in and permanently connected to a water line. The water is filtered before being supplied through the tap at the sink.

Reverse osmosis works by passing water through a membrane strainer, which filters out all but water particles. A carbon pre-filter traps the organic debris and chlorine that might otherwise harm the membrane.

The cleaned water flows to the faucet; the rest, together with the contaminants, goes down the drain.

Reverse osmosis systems are more expensive than most other filter systems available on the market, and they need their filters replaced in the low three figures.

However, sodium, arsenic, barium, hard metals (such as aluminium), and other contaminants are removed by these methods. Their waste-to-water ratio is high.

Dual Stage filter

Dual-stage filters remove salt, chlorine, and heavy metals by filtration and ion exchange, but they leave trace minerals like potassium in the water, beneficial to the human body.

Water flows through two carbon filters before entering a tube attached to the facet return line. Filters of this sort can be mounted beneath the sink or on the counter.

Dual-stage filters are simple to operate and maintain, but they must be installed by a competent plumber. Although, the size and the quality will differ among manufacturers, dual-stage filters cost in the low three digits.

Distillation filtration

Boiling the water produces steam, then put into a separate cooling box by a fan. The distilled water process removes microbial contaminants, heavy metals (lead, aluminium, copper, and arsenic), pesticides, salt, and a range of other pollutants.

The downside of distillation is that all minerals, even beneficial, are filtered out. In addition, this method requires more energy in the form of electricity to boil the water, and the entire process can take up to 6 or 7 hours.

Everything from small-batch processors the size of a coffee maker to gigantic under-sink continuous flow devices is used in distillation. Each day, a small batch processor with a capacity of five quarts may create four gallons of water.

A large continuous flow machine creates 10 gallons of water each day with a four-gallon storage container. The system’s price varies based on how much water is needed each day and can vary from a few hundred dollars to over $1,000.


The sodium level of softened water does not impact most people, but it is vital to be aware of the choices available to remove the salt from softened water or use one of the finest salt-free water systems. Installing a reverse-osmosis system to supply filtered, pure water is typical.

Not only will salt be removed from your drinking water using this solution, but you’ll also have peace of mind knowing that many other toxins will be eliminated as well. Microbes like giardia and salmonella, nitrates, and PFAS are among them.
