Understanding the Reverse Osmosis System: Insights from an Itasca Water Purification Company

Reverse osmosis system at a house in Itasca, IllinoisWhen it comes to obtaining clean and highly purified drinking water, no water purification system surpasses the reverse osmosis system.

Looking for more information about reverse osmosis systems? This Itasca water purification company has you covered. Here is everything you’ll need to know:

The Reverse Osmosis Process

The reverse osmosis process is fairly straightforward. Generally speaking, it includes the following steps:


When water first enters a reverse osmosis system, it goes through a series of pre-filters. These filters are responsible for removing sand, dirt, and other types of sediment from the water. They’re highly effective in doing so, and they will prepare the water to be sent through the system’s semipermeable membrane.

Semipermeable Membrane Filtration

Once the water has exited the final pre-filter, it will enter the semipermeable membrane. This is essentially like the heart of the reverse osmosis system.

The membrane removes almost every contaminant that the water contains — from chemicals, to minerals, to bacteria, and otherwise. Some of the contaminants removed by the semipermeable membrane include iron, arsenic, chlorine, and coliform bacteria.


After the water has exited the semipermeable membrane, it will enter a series of post-filters. These filters are responsible for purifying the water even further. They attempt to catch any contaminants that might still be remaining, and they are almost completely effective in doing so. Note, however, that reverse osmosis water will still contain trace amounts of some contaminants.


The process ends with containment. After the water has passed through the post filters, it’s sent to a large storage container. This container then holds the water until it’s ready to be used. To use the water, you simply turn on a faucet.

It’s important to note here that there’s a limit as to how much water the storage container can hold. With that being said, keep in mind that it’s possible to run out of reverse osmosis water if it’s used in large quantities.

Why Install a Reverse Osmosis System?

You’ve now read about the process of reverse osmosis. However, why should you install a reverse osmosis system in your home?

To Obtain a Steady Flow of Highly Purified Water

One of the main reasons to install a reverse osmosis system is to obtain a steady flow of highly purified water in your home. This water possesses the quality of bottled water, and it’s readily available to you whenever it’s needed. Reverse osmosis systems are more cost-effective than buying bottled water, plus they’re more convenient.

They’re Affordable to Run

Are you nervous about the cost of running a reverse osmosis system? Don’t be! These devices are run on water pressure. In other words, you won’t notice any increase in your energy bill.

They’re Great for Cooking

Highly purified water isn’t only great for drinking. It’s great for cooking as well. Because it contains no excess contaminants, it does very little to impair the consistency of prepared foods. This allows for consistency and quality in your cooking.

They Take Up Very Little Space

You might be surprised to hear that reverse osmosis systems are relatively small. In fact, in most cases, they can be installed directly underneath sinks. You won’t have to worry about your reverse osmosis system taking up your storage space.
