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. Our company has been in the water filtration business since , 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. Reverse Osmosis systems can remove pollutants from water including lead , pesticides , fluoride , pharmaceuticals, arsenic and much more. And with a carbon filter , an RO system can also remove chlorine to improve the taste, odor and appearance of your water. The process is fully automated, effective and simple to maintain.
Please wait My Account Cart. Does Reverse Osmosis Waste Water. A loaf of bread requires about gallons of water, and a pound of cheese takes about gallons. So a simple cheese sandwich takes about 56 gallons of water. Throw in a small bag of potato chips at 12 gallons and you just ate about 68 gallons of water. Add some turkey and it jumps to gallons! The only argument lacking reason is yours! Give it a rest. You have no argument.
It's 3 gallons of water wasted for every gallon used and depending on how you use it, it can be far worse than that.
Ron, The amount of waste depends upon the system. Some are , but we have systems that waste 1 gallon for every 4 gallons made. I too originally thought that the tone was a little flippant, but reading through these comments I get the point. Yes there is some waste, but there are ways to use the leftover and in comparison it does seem worth it. I drive a hyrbid and conserve when I can.
I too thought about getting 5 gallon jugs of water while I was at store shopping , but it doesn't seem to make sense. So I load 4 -5 gallon jugs drive home and feel like hooray I'm getting clean water and not harming environment. But if I do that couple times a month I have used more MPG carrying that load and adding to landfill.
Also as mentioned if that water I'm so happy buying or refilling jugs was made from RO in the first place I'm really not helping.
I think point he is making is we wash our cars in the car wash without a second thought, or some brush their teeth with water running, or taking longer showers or running water while shaving, or leaky toilet, faucet or a myriad of other ways we waste water with 0 actual benefit.
In that case drinking water that is going into my body, an actual good case makes no sense to balk at, considering. I'm sure some will disagree and then go water their lawn to keep it bright green etc etc, but if nobody has a better idea or alternatives not really a point in attacking the author. Thanks Mike, We are always trying to conserve water, but some people just lose their minds over nothing, so I just give it back to them. How do you like the warm water?
How much do you have to run until it cools down? UV consumes energy too and over time, the fittings become embrittled from the heat. Watch for leaks. Since RO removes a much larger spectrum of contaminants than any other process, there's no way filtration can have a higher clean water rating.
It's scientifically impossible! I saw online that older models had the light on all the time so that may have made warm water? That's funny. If the light is not on all the time, the little critters can just swim on past it. Good luck with killing the bacteria. We rely on our RO system to provide clean, safe water for consumption, ice production, and use it in the humidifiers as well. I have never seen so many idiotic comments in one place.
Mark you may as well just give up. Let these people just go buy bottled water and be done with it, they will never get it. Is RO wasteful? Well humans are wasteful. We are animals adapted to using and consuming our environment.
The problem with this post is that valid arguments and bad arguments are presented as equal, which is triggering people.
As a fact people need to wash clothes as a health issue, even more so wash dishes. The pathogens in both present not only a very real danger for yourself and family but is a public health issue. Travel to India or SEA where hygiene on these very issues are not to first world standards and immediately this is an asinine position.
So you do need to wash dishes and clothes. This is where ppl are getting stuck on. Logical fallacy invites challenge. Back to the original question, is RO wasteful? Assuming that one would purchase bottled water, no not really. Since bottled water Is often RO. If the comparison is to filtered water, then yes you could make that argument. RO is definitely superior it does use more water but if you take care to turn off the water brushing your teeth and unnecessary flushes, doing dishes you can get much of it back.
Mark Timmons is obviously an angry, biased, idiot who doesn't understand that water will soon be more expensive than gasoline. We can create new, and more efficient energy sources, but water is finite. Also, using the waste water from the osmosis process outside to water plants is crazy. The sodium is exactly what many plants don't care for if anything, put it in the ground; it'll get back to the aquifer. I'd say he's a water 'charlatan', not a water 'doctor'.
Never seen so many excuses from an 'expert' to avoid the ever more important concepts of conservation of all natural resources. You just convinced me to stay with my Brita pitcher, and avoid your wasteful, expensive nonsense. If you think a Brita pitcher will remove many contaminants, you are delusional.
I would advise you to get more education about plants, sodium levels and many other aspects about water. I'm not angry at you and I hope you seek help to get better. Good Luck. Guy Stocker. Thanks every one for all your arguments. Was a good read and very entertaining. I was upset to find out about the wastage after I had bought the system only a week ago. But just as shocked that our government allows these systems in our country. But thanks to all the clever people here I will now get a holding tank for the waste water and a pump connected to my washing machine and dish washer and use the RO waste water to do the cleaning work.
Then my family can enjoy their 3 gallons of RO water a day while I knock back a few beers with some Rum and Coca cola, Because only drinking RO Water for the rest of my life so as not to use my body as a filter is what I call a "Waste " of life. But thanks guy's and girls for your combined input I will defiantly do the tank pump set up with the waste water.
Josh McCoy. Great article. Answers my RO question about efficiency. I actually have 2 previous systems from you guys. Thanks Mark!
That way, the reject water will be used to flush toilets, thus won't be "WASTED", but rather used "efficiently", and all the people not getting IT, will be happy. Just combine RO with toilet flushing system and rake in the big bucks.
BTW, these zero waste systems will fill landfills with used RO membranes. I wonder what the environmentally "conscious" folks have to say about that. Also, thanks and kudos to US water systems to allow you to speak your mind, even if abrasively towards certain people. In today's corporate limitations, such is a rarity.
Many lives are lost to unclean water even today. I rather save the sick time or death and "waste" some water - than the other way around.
We had the film in the dish washer, and film in the showers. Installed a water softener for the whole house and have a 20 GPD reverse osmosis under the kitchen sink just for drinking water. We have no more films, and our drinking water is superb and registers about 3 ppm of dissolved solids, close to distilled!
We are very happy with the setup and would recommend this solution to all. I m using it to clean windows. What an absolute wast of water. My garden got watered fair enough. But I'm chucking a way more than I use. What kind of system do you have? That means they waste a godawful amount of water.
You may be wasting 6 gallons for every gallon made. That's why smart window washers use our engineered systems which waste just 1 gallon for very gallon made. You should consider the benefits. Thanks for your insights. How "contaminated" is the by product from RO? Could it be utilized for non-potable functions such as clothes, dish and sundry other cleaning functions?
Lawn and garden irrigation systems? I assume no problem passing through a toilet system and entering the drain field? YUP Agree with the Doc! If you believe the waste theory and it bothers you that much! Save that "wasted water" to put on your garden the plants will enjoy it! There are other solutions if you are inventive!
Hi, this might be helpful in regards to ro efficiency. Ro membranes are rated at different efficiencies, so start off with a low waste model. For a more detailed overview of how reverse osmosis works, jump to it here. All other types of water filters — mechanical filters i. Essentially, all the fresh water that flows into these filters, flows out as treated water minus the contaminants.
Some RO systems do in fact use way more water than they should — that is wasteful! I do not believe any water should be wasted pointlessly.
The reverse osmosis debate is one of the most contentious water debates in America. RO naysayers say that water usage is a huge problem with reverse osmosis. Take hand washing for example. Hand washing is one of the best ways to protect yourself, your family, and those around you from getting sick. When you wash your hands with soap and water, all the water goes down the drain.
Is hand washing a wasteful and inefficient activity? From a water usage standpoint, yes. However, using water to wash your hands provides significant health advantages, just like drinking water safe does. I do strongly believe in carrying out these activities with the environment in mind and doing them as efficiently as possible though. However, I think that everyone should determine if reverse osmosis is actually best suited for their water conditions or if they could accomplish their water goals with a different, more efficient technology.
Plus, I like the taste of reverse osmosis water. Generally, the reverse osmosis process takes 4 gallons of water to make one gallon of purified water. The amount of water used is based on the water supply and the RO system itself. For example, if the feed water is loaded with lots of contaminants, the system has to work harder and use more water than if the water supply had less contaminants.
The chart above shows approximately how many gallons of reverse osmosis waste water per gallon of product water average water conditions. This comes down to the membrane. With time and use, it fills with more contaminants, so the concentrate stream increases to keep producing pure water, and more water is ultimately sent down the drain. There are water purification units designed to use minimal to no water read more about these below.
It impacts how much water a RO system uses. The higher the recovery ratio, the less drain water. However, some RO designs cannot handle high recovery rates since it leads to membrane scaling and premature fouling. Keep this in mind if the manufacturer is stating an exceptionally high recovery rate. The recovery rate is what would be recovered if the incoming water is near perfect.
