CHAPTER 19 SYSTEMS: ENVIRONMENTAL CONTROL AND LIFE SUPPORT SYSTEM—SUPPORTING THE HUMAN ELEMENT OF THE ISS 342 Figure 6. A full CWC (left) and the “water wall” in Node 1 (right). Note that a CWC is about 61 cm (24 in.) long with a diameter of 24 cm (18 in.) and can hold about 43 liters (12 gal) of water. Wastewater Tank Fluids Pump 2 3 4 1 5 Urine from Waste and Hygiene Compartment or Russian Water Container Recycle Filter Tank Assembly (Accumulates and stores brine for disposal) Purge Pump (Removes gases from Distillation Assembly) Coolant (Promotes condensation within Purge Pump) Purge Gas to Cabin Separator (Separates water from Purge Gases) Product water to Water Processor Assembly Distillation Assembly (Distills wastewater) Figure 7. The Urine Processor Assembly schematic. Water comes from the waste storage tank to the Advanced Recycle Filter Tank Assembly and through a distillation process before gases are removed in the purge pump.
