Shuttle water test

The Immobilized Cell Bioreactor (ICB) and the Trickling Filter Bioreactor (TFB) are part of the water treatment system. The ICB treats water from the laundry, shower, handwash, oral hygiene, urine and humidity condensate. The TFB is used to convert the ammonium (NH4=) found in the wastewater to nitrite (NO2-) and nitrate (NO3-) which are more easily removed by other processes.


Shuttle work station

This is a piece of our water recovery post-processing system. It is a commercial off-the-shelf unit that we decided to investigate to perform the last "polishing" step in the process. The back was removed here to get a digital image that could be used by the outside crew to modify a second unit to be used outside the chamber.


Doing laundry

This washer/dryer combination is certainly a space saver and it only uses about 13 gallons of water a day. But unless you catch it at just the right time, we find that tee shirts come out a little wrinkled - and as that's standard dress in the chamber, you learn to catch it at the right time. You know, John and I both have the same question – how do you fold fitted sheets?
