How Does Reverse Osmosis Work?

Is Reverse Osmosis Just for Drinking Water?

How Much Water Should I Be Drinking?

Cincinnati, Ohio’s Highest-Rated Provider of Reverse Osmosis Water Purification Systems

Reverse Osmosis Systems Cincinnati - Ohio Valley Pure Water - happy-glassGet clean, purified water straight from your kitchen tap or refrigerator dispenser. The quality of water will always be an important topic. At times, it can be difficult to know whether or not the water you’re drinking has harmful contaminants in it. For this reason, Ohio Valley Pure Water installs Reverse Osmosis (RO) systems so you can be sure your water is always safe to drink. An RO system will remove any unpleasant tasting impurities and potentially harmful contaminants that are in your water. This helps you and your family feel better about the water you drink and use every day

Advantages of Drinking Reverse Osmosis Water 

Water quality awareness has been increasing. As this topic increases, the demand for better water treatment solutions intensifies as well. Reverse osmosis water has numerous benefits for you and your family. Having pure, clean water to drink is essential to keep your body working correctly. 

Fewer Contaminants

Water that’s contaminated can negatively impact your health. With a reverse osmosis system installed, you can significantly reduce the number of contaminants that are found in your water. Our systems can reduce contaminants such as lead, copper, radium, arsenic, and more. If you want pure water, then a reverse osmosis system is exactly what you need. 

Eliminates Sodium 

Too much sodium can cause high blood pressure, liver problems, and kidney disease. One of the major benefits of installing a reverse osmosis system is that it filters out the sodium in your water. 

Saves Money 

Buying bottled water will become a thing of the past with reverse osmosis systems. Many people don’t like the taste of tap water and will resort to spending hundreds of dollars on bottled water. By installing a reverse osmosis system, it will pay for itself and help you save money by never having to buy bottled water again.

Frequently Asked Questions About Reverse Osmosis Systems

What is Reverse Osmosis (R.O.)?

We can best answer this question by first briefly explaining natural "Osmosis." This is nature's process by which moisture and nutrients are taken up through the root systems of plant life to its very outermost leaves. Moisture drawn from the soil passes through cell walls cell by cell in this process. It is scientifically described as the passing of a less dense liquid through a semi-permeable membrane into a thicker fluid until there is an equal density of fluid on either side of the membrane. The process is repeated cell by cell until the nourishing fluid reaches the very outermost twigs and leaves of a plant. This process also takes place in our own bodies and the bodies of other animals.

Reverse Osmosis is named because man has reversed nature's process. R.O. forces raw tap water, which is the denser liquid, against a membrane by utilizing the city's water pressure. When forced against the highly polished surface of the membrane, the water molecules dissolve in the thin membrane layer and diffuse through it molecule by molecule, forming pure water on the product side of the membrane and in the process leaving 95% - 99% of the contaminants behind.

What kind of impurities are in my water?

We will let the Greater Cincinnati Water Works answer this question. In the Safe Drinking Water Report, they state:

"As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity [sewage].

Contaminants that may be present in source water include: microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations and wildlife; inorganic contaminants, such as salts and metals... pesticides and herbicides... organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production... and radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities."


What happens to the impurities that were in the water?

They're washed down your kitchen drain. You see, unlike filters, the R.O. membrane is self-cleaning. As it flows through the module, the source of water divides into two streams. One stream is forced through the membrane by diffusion because of the water pressure. The second stream serves as a "blow down" and carries away rejected salts, particulate matter and other impurities to the drain. Therefore, there is no accumulation of debris on the pressure side of the membrane as a function of time. The face of the membrane always stays clean.


Does Reverse Osmosis remove minerals that are essential to health?

Yes, all R.O. systems remove about 99% of the good minerals in tap water. Only Ohio Valley Pure Water offers at no additional cost, their 6-stage R.O. with the mineral/alkaline filter. It puts natural calcium, magnesium, and trace minerals back into your purified water after the R.O. process.


Does Reverse Osmosis change the pH balance of the water?

Yes, by removing all of the contaminants in the water it naturally lowers the pH in the purified water to below 6.9 or to an acidic state. Only Ohio Valley Pure Water offers at no additional cost their 6-stage R.O. system with the mineral/alkaline filter. It raises the pH in the R.O. water to an alkaline state, in many cases between 8.5 to 9.0 pH.


What is the ratio of wastewater to the pure water produced by your R.O. unit?

Our 50 GPD unit has a ratio of 1:3 depending on your water temperature and water pressure. Therefore, for every 3 gallons of pure water produced, 9 gallons of wastewater will go down the drain. If you were to use 3 gallons of purified water a day (with 9 gallons of waste water going down the drain), you might see an increase in your water bill of about 25¢ per month.


Are there R.O. units that waste no water?

No, all R.O. unit’s waste water, some more than others.  Some companies claim to have "no waste water" units available. The reality is that they run the waste water line to your water heater. This causes the water heater to go out more quickly due to the extra buildup of contaminants.


Does your R.O. unit continue to make water when it’s not being used?

No!  When the 4-gallon storage tank is full, the R.O. shuts off until used. Whatever amount of water you take from the tank, the RO replaces the water that you just took and then will shut off again.


How much pure water will your R.O. unit make?

The 50 GPD Reverse Osmosis system will produce a maximum of 50 gallons of purified water in a 24-hour period.  Although most families will never use this much water, such a fast recovery rate is convenient. Since the tank holds 3.2 gallons of purified water, you could use it all at once, and it would only take 1.5 hours to refill completely. Systems with a lower GPD rating will take longer to refill and will send more waste water down the drain, compared to an R.O. system with a higher GPD rating.

Is it important to purchase an R.O. unit with an electronic monitoring faucet?

No. An electronic monitoring faucet has a green light that indicates when the water is supposed to be pure and a red light that indicates when the filters are bad. The monitoring device is very deceiving because it is only monitoring the chlorine in the water. For example, if the R.O. unit were not removing the bacteria and viruses but was removing the chlorine, the light would stay green. Therefore, from our experience, these electronic monitoring faucets are not reliable.  As long as you have your R.O. unit serviced at least once per year, monitoring is not necessary.

What is the difference between faucet-mount or pitcher filters and the R.O. unit?

Faucet-mount filters, pitcher filters, and refrigerator ice/water filters can reduce certain contaminants from your water by the use of granular activated carbon. In most cases, they are used to reduce chlorine, lead, odor, and taste. Carbon filters eliminate contaminants down to 0.5 microns in size, and R.O. filters down to 0.0001 microns. Therefore, there are tens of thousands of contaminants that are removed by R.O. and not by faucet-mount, pitcher or refrigerator filters.

Where do you install the Reverse Osmosis unit?

The R.O. system can be installed under the kitchen sink or in an unfinished basement. It can also be attached to your ice maker.

If I move, can I take it with me?

YES!  It's 100% portable. It only takes about 10 minutes to disconnect.

What kind of warranty comes with the R.O. unit?

For a period of 3 years from the date of purchase, the manufacturer will repair or replace any part of the Reverse Osmosis unit itself except for the filters and local service charge. Warranty is voided if customer services or changes their own filters.  For any other questions, ask for a copy of the warranty.

How long will your R.O. unit last?

On average of 10 to 14 years, depending on three things: 1) That regular and/or yearly maintenance is done correctly. 2) The nature of water is purifying. 3) Water pressure. Between 45 psi and 80 psi are ideal. 45 psi is too low, and 80 psi is too high.

Is it necessary to change the filters every 12 months?

Yes, it is essential. The filters that we use in our R.O. unit are good for 12 months when using city/county water. By changing the four pre-filters regularly, you will eliminate dirt and chemicals in the water that clog the membrane. After 12 months of use, the carbon filters can have bacteria growing within the filter media. Regardless of how much or how little water you use, it is highly recommended that you have your filters changed every 12 months.  It is time and not the usage that breaks down the filters. Well water and cistern water may necessitate more frequent filter changes.

What is the importance of water pressure to an R.O. unit?

It is the pressure that forces the water through the membrane for purification and flushes the contaminants down the drain. Water pressure below 45 psi is generally considered insufficient and should include a pressure booster pump. Water pressure above 80 psi is generally considered too high and should consist of a pressure reducer valve.

Will a whole-house water softener harm the R.O. unit?

No, calcium and magnesium (limescale) are two of the hardest minerals for the R.O. membrane to remove.  Sodium (added to the water by the softener) is much easier on the membrane, and it will reject 99% of all sodium in the water. With a water softener, you will always get 12 months out of the pre-filters and 4 years out of the membrane.

Other than drinking & cooking, what other benefits are there to owning the R. O. unit?
  • Peace of mind
  • No more carrying bottled water
  • Healthier
  • Medications can do a better job
  • Ice and drinks taste better
  • Ice is clear and not cloudy
  • More pure coffee and tea
  • Saves on concentrated juices
  • Pets and plants love it
  • Aquariums look better
  • Easier cleaning — windows, and mirrors shine, irons last longer, humidifiers last longer
  • And more
