Research paper thumbnail of Experimental and Analytical Studies of Full-Scale Amberlite Water De-Ionizing Bed Structure for Space Application

A critical component in the oxygen generation assembly for long term human habitation system in s... more A critical component in the oxygen generation assembly for long term human habitation system in space is the de-ionizing (DI) bed - a packed bed of ion-exchange resin beads - that purifies water by removing ions (dissolved salts and organic impurities) from reclaimed water. The DI bed shrinks during the course of its operation. For the bed to work satisfactorily in microgravity environment, it is required that the bed is kept compressed and this is done with the aid of a compressed spring mechanism placed at one end. The objective of this current research work is to study the behavior of the full-scale DI bed experimentally in order to gain an understanding of how a force applied at one end is transmitted along the length of the bed and to determine an analytical model that fits experimentally obtained data. A series of experimental investigations was carried out in several lengths of full-scale DI bed made of Amberlite IRN- 78 ion exchange resin to determine load-deflection charact...
