Reverse Osmosis (RO)

What is Reverse Osmosis?

To understand Reverse Osmosis (RO), let’s first examine the concept of osmosis. Osmosis is the natural process by which molecules of a solvent tend to pass through a semipermeable membrane. They naturally move from a less concentrated solution into a more concentrated one. Thus the process equalizes the concentrations on either side of the membrane.

With plants, special cell walls act as the membrane through which water passes, bringing with it the nutrients that feed the plant.

In water purification, a synthetic membrane separates water with a high concentration of contaminants from water with a low concentration. Reverse Osmosis forces the water with the high concentration through the membrane to the other side using normal water pressure. Only molecules of water can easily pass through that membrane; so the water emerges on the other side purified. This leaves the impurities behind and rinses them down a waste drain.

How It Works in Our System

Even though we use very scientifically advanced membranes, the contaminants on the concentrated side can damage them. Thus, we need to service the water filtration unit once a year to maintain its effectiveness. This system gives you clean, pure, natural water that can be used for all your water needs, including drinking, ice cubes, watering plants, etc.

Reverse Osmosis purifies water and makes it taste better, fresher and cleaner. It treats a wide range of aesthetic contaminants that cause unpleasant taste, color and odor. Plus, it is very effective at treating health contaminants such as arsenic, asbestos and atrazine (e.g., herbicides and pesticides). It also treats chemicals such as fluoride, lead, mercury, nitrate and radium. You will never have safer, purer water than this.

Alternatives to Reverse Osmosis

Probably the two most popular alternatives to Reverse Osmosis (RO) for filtering water are 1) to use a pitcher filter, such as Brita offers; and 2) to use a faucet-mounted filter, such as PUR offers. Both are adequate for improving the TASTE of water; but neither provides the filtration of harmful and unsafe elements the way a Reverse Osmosis system does.

Why did I not list bottled water? Bottled water is very often just Reverse Osmosis water in a bottle. The plastic bottles are the problem. They are not biodegradable, and therefore are a hazard to the environment. According to,

“In general, there are no major health advantages to drinking bottled water… The only time it’s generally recommended that you drink bottled water instead of tap water is if you’re in a group at high-risk for infection…”

Most people drink bottle water for the taste, not the health benefits.

What about spring or well water?

Why did I not list spring or well water? Spring and well water vary in composition, depending upon the source and location. Just because the label on a water bottle reads “spring water” doesn’t mean it’s better for you than what is coming out of your faucet. It may taste better, but taste does not necessarily mean “better for you.”

In order to KNOW that you are getting the best water for your family and staff, you need to start with good water and then filter it to remove the harmful elements. Even spring and well water need to be filtered. And there is no better way to do that than with a Reverse Osmosis (RO) system from Crescent Hills Water.

Still not convinced?

Reverse Osmosis has the ability to remove 99% of minerals and chemicals that make water unsafe to drink, as well as remove the bad-tasting elements, such as chlorine. So it makes water both safe to drink and good-tasting. An RO Unit can remove poisons such as arsenic, asbestos, atrazine (e.g., herbicides and pesticides), lead, mercury, radium and nitrates. It can also remove fluoride and excess sodium that affect water’s purity and taste. It does not remove minerals that are vital for good health.

Reverse Osmosis is a more reliable way to purify water for both your family and your employees. So, why doesn’t everyone use a Reverse Osmosis system? Mostly, they don’t know about it. But if they do, they don’t understand the difference. Which is why we offer a free trial. We’re convinced that once a customer tries our Reverse Osmosis system, they won’t go back to bottled water, faucet filters or any other alternative filtration system. That’s how confident we are that you’ll like what you taste.
