Engineering Evaluation Of Reverse Osmosis And Ion Exchange Demineralization For Use In A Self Contained Air Transportable Wastewater Renovation Unit

This report documents the engineering evaluation of a demineralization process for use in a wastewater treatment system for renovating a combined advanced military base wastewater consisting of kitchen, laundry, and shower wastes for reuse purposes including drinking. Evaluation of demineralization processes was limited to ion exchange and reverse osmosis. Data supporting this evaluation were obtained from published literature, manufacturer's recommendations, and experimental analysis. The two processes were evaluated using the following parameters: Cubage, total package weight, logistical support requirements, operating skills required, maintenance requirements, complexity of component assembly, power required, availability of fabrication materials, water recovery capability, odor control provisions, and cost per unit volume of product water. It was determined from this evaluation that either process would produce a water which would meet the required specifications. However, evaluation of all comparision parameters favors the use of reverse osmosis. (Author).
