Traditional Float Tanks rely on a continuous recirculation approach while the solution remains inside the tank, similar to the system used in a hot tub. This filtration method can overlook certain areas within the tank where the solution doesn’t circulate effectively. When some Float Tanks advertise over 100% filtration, they’re referencing the solution volume they can process between sessions.
A float tank containing 600L of solution, paired with a pump capacity of 300 litres per minute, would theoretically achieve 300% “filtration” during a 6-minute client transition. While this may sound attractive, the results aren’t as good as they seem.
Imagine you have a 100L bath tub filled with water and glitter that you wish to remove. You are given two ways to remove the glitter.
- Remove a 1L bucket of water, filter out the glitter, then pour it back into the tub, and repeat this for 100 buckets.
- Remove all 100L of water into a new container while pouring it through a filter. Then pour the 100% filtered water back in to the bath tub.
The issue with the first method is that while you have filtered out the volumetric equivalent of water, you cannot 100% guarantee that all the glitter will be removed. The glitter would redistribute around the water constantly and it would be extremely difficult to remove all of it. This is how a traditional float tank cleans itself. Dirt, skin particles and other contaminants float and redistribute constantly, making it extremely difficult to remove all contaminants.
To put this in a real world scenario, if a tank was guaranteed to remove 75% of contaminants per 600L filtered, there would be 25% of contaminants remaining after the first pass, 6.25% remaining after the second pass and 1.56% remaining when the new customer enters the tank. In order to hit 99.99% filtration, 3000L would have to be circulated.
