How Do Reverse Osmosis Filtration Systems Work?

Which Reverse Osmosis System?

It can be challenging to determine what its the best filter filtration system for you home. Lets start with Reverse Osmosis point-of-use systems. How Do Reverse Osmosis Filtration Systems Work? The reverse osmosis process works simply by stripping regular water of contaminants, particles, salt, viruses, and minerals to give you the most pure H2O available. How does RO work? What is a RO membrane? Reverse osmosis works by using applied pressure to filter regular water is through a semipermeable membrane; which is comprised of several thin composite membrane layer, which is then coiled.

RO Wastewater

One concern regarding Reverse Osmosis water filtration systems is the production of wastewater. RO systems do expel waste water which is used to flush the membrane as it filters for contaminants. Many of the RO systems on the market have a wastewater ratio of 4 gallons for every 1 gallon of pure water produced, at their most efficient. As the tank on a traditional ro system fills the more back pressure it creates and less water is able to pass through the membrane. As less water passes through the RO membrane the more water is rejected as waste water.

Efficient RO Systems

For maximum efficiency and water savings using a reverse osmosis filtration system is not the typical way a family consumes water. RO systems are intended to operate by emptying a full tank (ave 1.5 gallons) at a time. Most commonly for at home consumption this isn’t plausible as people tend to drink their water one glass or pot of water at a time. Given this created back pressure issue the typical RO systems waste between 8-10 gallons of water to produce one gallon of drinking water, based on real-use situational testing by Pionetics. So the each filtration systems real life use is consistently operating at its most inefficient.

Brondells Circle RC100 Reverse Osmosis System eliminates the back pressure and excessive waste by use of an internal tank thus eliminating the backpressure to maintain a steady window of wastewater opposed to such dramatic swings that a traditional RO tank system would have. This unique system makes the Circle RC100 stand out from the pack in ease of use and the elimination of back pressure!
