Does Reverse Osmosis Waste Water

Our Atmospheric Water Generators produce pure DRINKING water without waste. Go Back.

For every 1 liter of water filtered, a RO system uses up to 4 liters of water to flush the contaminants out. So YES it does waste water and sends it directly to the drains via a permanent waste connection.

However, to be fair, some more sophisticated units re-cycle the flushing water, but there is a danger of it eventually contaminating the produce safe water. The waste water could also be re-directed for other purposes not related to drinking, food preparation, cooking or bathing. Do not use for pets.

FACT CHECK ! Don't take our word for it, go to waterdefense.org and read about it for yourself.

So producing 25 liters per day of treated drinking water wastes up to a further 100 liters per day.

This waste could be critical in an off grid or intermittent / reduced supply situation. Don't waste precious water.
