Does RO Waste Water?

Does a Reverse Osmosis (RO) Water Filtration System WASTE Water?

The dictionary defines waste as 'To consume, spend, or employ uselessly'.RO faucet

If you use 20 gallons of water to hand wash your dishes after a meal, is that wasting water? If you have dirt on your hands and use water to rinse off the dirt, are you wasting water? Most would say, "no", but simply using water to wash off impurities. 

So it goes with the  reverse osmosis process. Water is used to rinse impurities away-- water is what is needed to produce clean water during the reverse osmosis filtration process.

How Does Reverse Osmosis Work? 

In simple terms, the RO process utilizes household water pressure to push water through a series of water filters including a semi-permeable membrane. 

Because the pressure is higher on the outside of the membrane, the small water molecules pass through to the lower pressure side, and the larger molecules of contaminants are rejected and cannot push through. These trapped impurities are then washed away by—you guessed it—water!

The small water molecules that were able to push through the RO membrane, are collected in a storage tank and you have pristine water ready for consumption.

How Much Water is Used During RO Process?

This process generally requires about 4 gallons of water to produce one gallon of clean, filtered water. The amount of water used in the filtration process can vary depending on water temperature, contaminants present, and amount of dissolved solids in the water,

Whether you're on private well water or city water, in our world today all kinds of contaminants are finding their way into our water. We're talking  pesticides, herbicides, pharmaceuticals, arsenic, VOCs, lead, and more. And while public water suppliers do their best to provide clean water, many contaminants are NOT regulated and many times never detected or removed.PuROTwist Reverse Osmosis Filter System

What About 'Zero Waste' Systems?

Some water filtration systems try to reduce water usage by circulating the water back into the RO system repeatedly. But that approach quickly wears down the filter components and system. 

Other systems attempt to "recycle" the water by sending the contaminated water concentrate to the hot water line or funnel off for other use. But that doesn't make sense as RO waste water contaminant level is high and would mostly likely be unsafe for drinking or cooking.

Reverse Osmosis: Proven Method for Clean Water

RO systems are one of the most effective water filtration systems on the market. Reverse osmosis filtration can remove pollutants from water including  nitrates, pesticides, sulfates, fluoride, bacteria, pharmaceuticals, arsenic and much more. And with a carbon filter, an RO system can also remove chlorine and chloramines. Check out our most popular Reverse Osmosis drinking water system.

Best of all, RO filtration provides healthy drinking water with improved taste, odor and appearance. The reverse osmosis process is fully automated, effective, and simple to maintain.

Our company has been in the water filtration business since 1991, and we've found that reverse osmosis consistently proves to be one of the most effective ways to filter water.
