What Is Reverse Osmosis Water?

Reverse osmosis water is a way to ensure your water is pure and free from impurities. It's a water treatment process using a unique membrane to filter contaminants. In the end, it leaves you with clean, refreshing H2O.

Reverse Osmosis removes things like the following:

  • Sediment particles

  • Chemicals like chlorine

  • Heavy metals

  • Bacteria and viruses

The result? Superior water quality that's safe and delicious. So, reverse osmosis is the way to go if you want a reliable and effective water filtration system.

How Does Reverse Osmosis Work?

In a reverse osmosis system, water passes through multiple stages of filtration. This is to ensure exceptional water quality. Here's a breakdown of how reverse osmosis works:

Pre-Filtration Process

In the pre-filtration process of reverse osmosis, water filters larger particles and common contaminants before reaching the reverse osmosis membrane. Let's look at the pre-filtration process.

A sediment filter captures larger particles like:

  • Dirt and sand

  • Rust and sediment

This prevents them from entering the reverse osmosis system.

After that, a carbon filter helps remove chlorine and chlorine by-products. This will improve the smell and taste of the water.

Finally, some pre-filtration systems may include other filters to target specific contaminants. For example, they have activated carbon filters for further chemical removal.

This pre-filtration stage plays a crucial role in protecting the reverse osmosis membrane and ensuring optimal performance and longevity of the system.

The Reverse Osmosis Membrane

Now, the water flows through the heart of the system. The reverse osmosis membrane.

This synthetic lining acts as a barrier, allowing water molecules to pass through it. All the while trapping dissolved solids. For example, the following:

  • Salts and heavy metals

  • Any pesticides

  • Certain bacteria and viruses

Post-Filtration Process

In the post-filtration process of reverse osmosis, the treated water undergoes additional filtration stages to enhance its quality further, beginning with carbon filtration.

Carbon filtration is a method of water treatment. It uses activated carbon to remove impurities from water.

Activated carbon, also known as activated charcoal, is a specially treated carbon form with a large surface area with microscopic pores. These pores effectively trap and absorb contaminants. It improves the following:

  • The taste of the water 

  • The water odor

  • The overall quality

During the carbon filtration, water passes through a filter containing activated carbon. As the water flows through the carbon, the following elements adhere to the surface of the carbon due to their affinity for the activated carbon's pores:

  • Organic compounds

  • Chemicals such as chlorine

  • Other chemicals

  • Some heavy metals

This results in removing these impurities, leaving behind cleaner, purer water.

Carbon filtration is commonly used with reverse osmosis to provide an additional layer of purification and enhance the overall effectiveness of the water treatment system.

Some reverse osmosis systems may also include a polishing filter, much like a final carbon filter, designed to provide an extra level of purification. 

Any remaining particulates or impurities that might have bypassed the reverse osmosis membrane are captured in the fine filtration stage, ensuring the cleanest water possible.

The post-filtration process is essential to achieve the treated water's desired taste, clarity, and purity. It provides you with a refreshing and enjoyable drinking experience.

Storage and Usage

Once the water has undergone the reverse osmosis process, it is stored in a dedicated tank for convenient access. When you turn on the faucet, the treated water flows.

Before hitting your container, it goes through one last carbon filter. I know, they’ve really outdone themselves with all the filtration, but hey, they only had you in mind. This ensures that the water you use for drinking, cooking, or any other purpose is pure, clean, and ready to quench your thirst.

What Does Reverse Osmosis Remove?

Reverse osmosis filtration is impressively thorough. It eliminates a wide range of contaminants that may be present in your water supply. Here are some of the most common impurities removed by a reverse osmosis system:

Sediments in Your Water Supply

Sediments in your water supply refer to small particles, such as dirt, sand, rust, or debris, that can be present in the water. These sediments can affect the following:

  • Water clarity

  • The taste of the water

  • Clog pipes

  • Even damage appliances

Proper filtration, including pre-filtration in a reverse osmosis system, helps remove sediments and improve water quality.

Chemicals Such as Chlorine

Chlorine in water refers to the chemical compound chlorine (Cl2), often added to public water supplies as a disinfectant. It is used to kill or inactivate harmful microorganisms, including bacteria and viruses, that can be present in the water.

Chlorine is crucial in ensuring drinking water is safe and free from waterborne diseases. However, it can also contribute to a distinct taste and odor in the water, which some people may find undesirable.

That's where reverse osmosis filtration comes in. By passing through the pre-filtration and carbon filtration stages, chlorine is effectively removed. This results in water being free from contaminants while tasting and smelling better.

Say goodbye to that chlorine aftertaste and enjoy refreshing, clean water!

Heavy Metals

Heavy metals in water are metallic elements with a high density and can be toxic to human health when present in excessive amounts. These metals can enter water sources through the following:

  • Natural processes

  • Industrial activities

  • The corrosion of pipes and plumbing fixtures

Examples of such metals include the following: 

  • Lead and mercury

  • Arsenic, cadmium, and chromium

Heavy metals are resilient and difficult to degrade, posing a concern when consumed. We don’t want to scare you but exposure to elevated levels of heavy metals in drinking water has been associated with various health issues, such as the following:

  • Developmental delays

  • Organ damage

  • Neurological disorders

  • Even cancer

Fear not though! Effective water treatment methods, like reverse osmosis, are crucial in removing heavy metals and ensuring safe and healthy water to use.

Pesticides and Herbicides

Pesticides and herbicides are chemical substances used in agricultural practices. They are used for the following:

  • To control pests

  • To stop insect infestation 

  • Unwanted plants or weeds

These chemicals can find their way into water sources through the following methods:

  • Runoff from fields or gardens

  • Leaching from soil

  • Improper or illegal disposal

When present in water, pesticides, and herbicides can pose a risk to human health and the environment.

Exposure to these substances in drinking water can have various health effects. These include the potential risks to the following:

  • Nervous system

  • Hormonal balance

  • Even carcinogenic properties

Additionally, pesticides and herbicides can also harm aquatic life and disrupt ecosystems.

Reverse osmosis filtration is highly effective in removing pesticides and herbicides from water. Using a semi-permeable membrane, reverse osmosis systems can effectively trap and remove these chemical contaminants. As a result, it provides cleaner and safer water for use and reduces potential health risks associated with pesticide and herbicide exposure.

Bacteria and Viruses

Bacteria and viruses are microorganisms that can be present in water sources. They can be one of the most dangerous in respect of health risks.

Bacteria are single-celled organisms. Viruses, on the other hand, are even smaller and require a host to replicate. These pathogens can enter water supplies through various means. These include the following:

  • Sewage contamination

  • Agricultural runoff

  • Inadequate water treatment

Bacteria and viruses in drinking water can cause waterborne diseases such as the following:

  • Stomach problems such as gastroenteritis
