Pre-Treatment Solution for Water Recovery

The Pre-Treatment Solution for Water Recovery was developed by NASA Johnson to increase the amount of potable water recovered from the International Space Station’s urine processor assembly system. Turning wastewater, urine, or seawater into potable water requires three important steps: 1) pre-treatment, 2) distillation or membrane filtration, and 3) transport and storage of potable water and brine. This solution is added during the first step, consequently improving the next steps in the process primarily by reducing the formation of solid precipitates.
