Reverse osmosis technology uses high pressure to force water through an extremely fine semi-permeable membrane, filtering out dangerous inorganic chemicals, including lead, chromium 6, arsenic, uranium, nitrates and lots of other contaminants.
During this process, the contaminants that do not pass through the membrane are flushed away from the membrane. You may be familiar with how wasteful normal under-the-sink reverse osmosis systems are, sending anywhere from 3-5 gallons of waste water straight down the drain for every 1 gallon of pure water produced; that’s nearly 80% inefficiency!
AquaTru's technology recirculates a certain amount of waste water back through the system multiple times, boasting 80% efficiency. For every 1 gallon of tap water, 3/4 of a gallon of purified water is produced. This process flushes the filters to optimize performance and leaves concentrated contaminants in the tap water tank so you can easily discard it. The small amount of waste water should be discarded after each full tank is filtered. If you do not empty your waste water each time and instead "top-off" the water in the tap tank each time, you will cause extreme scale build up that will damage your AquaTru.
