Does Reverse Osmosis Waste Water
Do RO Water Filtration Systems WASTE Water?
Let us explain the reverse osmosis process this way: If you have dirt on your hands, how would you remove it? You would use water to rinse off the dirt. Does this mean you are "wasting water"? Most would say no, but that you're simply using water to wash the hands.
Simply put: in the Reverse Osmosis process, water is utilized to "wash" impurities out of your water, too. Yes, water itself is what is needed to produce clean water in the reverse osmosis process.
How Much Water do Reverse Osmosis Systems Use?
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.
Do 'Zero Waste' Reverse Osmosis Systems Work?
We're occasionally asked if 'zero waste" filtration systems (that recycle contaminated water) are a viable solution to filter and still conserve water?
The idea of 'zero waste' sounds good in theory, but in reality, we have not seen this technology work successfully, and here's why:
1) Zero Waste systems reduce water usage by circulating the contaminated water back into the system repeatedly. With a normal Reverse Osmosis system, this contaminated water is flushed out. But with a zero waste system, the contamination builds up higher and higher, often wearing down on filter components and water filtration system itself.
2) Zero Waste or recycled RO water systems attempt to reduce water usage by sending the contaminated-concentrated water to the hot water line. This means that users are washing their hands or dishes with contaminated water.
How Does Reverse Osmosis Work?
Before discussing water waste, it's important to understand how reverse osmosis water filtration works. In simple terms, the reverse osmosis 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.
Reverse Osmosis: Proven Method for Clean Water
Our company has been in the water filtration business since 2003, and we've found that reverse osmosis consistently proves to be one of the most effective ways to filter drinking water. But we invite you to learn more about the advantages and disadvantages of RO systems before making a purchase.
