Reverse osmosis is a drinking water system used to remove contaminants from water by pushing the water under pressure through a semi-permeable membrane. Reverse osmosis is an effective technique for addressing a wide range of contaminants. This one system can address many issues such as nitrates, lead, arsenic, radium, chlorine, and many other contaminants.

a reverse osmosis filtration system for drinking water

This system is installed under the kitchen sink with treated water provided by a separate gooseneck faucet. RO systems treat water “one drop at a time” and, therefore, a small holding tank collects the treated water. Models with a booster pump are also available to allow for filtration of the water line treating the refrigerator and ice maker. Designer faucets are available in many attractive finishes.

How Does Reverse Osmosis Work?

Reverse osmosis is an effective way to purify water, but how does it work and what are the steps in the process? First, the tap water flows through a sediment filter to remove dirt, rust, and other solids. From there, it flows into another type of filter for removing chlorine and other chemicals. Next, dissolved solids eliminated from the water and impurities are rinsed down a drain. The water goes through one last stage of filtering to ensure there are no strange tastes or odors before it reaches your glass. The final product is clean, delicious, and ready to be poured and enjoyed.

What Is Whole-House Reverse Osmosis?

This is more of a “specialty system” used in cases of saltwater intrusion. A whole-house reverse osmosis system is a large system that treats water for the entire household. Because water is produced “one drop at a time,” these systems include a large atmospheric storage tank and also a repressurization booster pump. These systems start at $16,000 and need much space within the home. Some county health departments do not condone use of these systems, as they place a heavy burden on your private septic system with the extreme amount of discharge water. For more information on this specialty system, please contact Water Doctor.

Is It Safe To Drink Reverse Osmosis Water?

Yes, reverse osmosis water is devoid of minerals, but ingesting mineral-free purified water is not harmful to your body. Minerals are essential to our cellular metabolism growth and vitality. We get the majority of these minerals from eating food.

Frequently Asked Questions

Do reverse osmosis systems waste water?

A reverse osmosis system uses more water than you actually consume, but it isn’t wasted. That excess water is necessary for the operation of your RO system.

You likely won’t see a significant difference in your water bill.

Does reverse osmosis make distilled water?

No, water purified through reverse osmosis differs from the method used to create distilled water.

RO systems use a semipermeable membrane to eliminate impurities and contaminants in your water supply. Distilled water is created by boiling water and collecting the resulting steam, which is then condensed back into liquid form.

Both methods can effectively remove a broad range of contaminants; however, RO systems are more efficient and cost-effective for residential use.

How long does a reverse osmosis system last?

A reverse osmosis system can last 15 to 20 years. Regular maintenance, such as changing filters, sanitizing and pre-charging the holding tank, and keeping the system clean, can help extend its life span.

How do you size a reverse osmosis system?

The general rule of thumb is to estimate the number of gallons of water used daily, then multiply that by 1.5 to determine the required daily production rate. Your water quality specialist can help you properly size your RO system.

Why do I need a separate faucet for reverse osmosis?

RO systems produce water one drop at a time, which collects in the small holding tank.  Most tanks only hold 1.5 to 2 gallons of water at a time. Once that is used, it could take two to four hours to produce more. Connecting to the main faucet would not be feasible. Larger storage tanks are available if space allows.
