The long range objective of this program is the development of a compact 4000 gallon-per-day waste treatment system to process non-sanitary wastes shower, operating room, kitchen, laboratory, x-ray, and laundry from the operation of a MUST Army field hospital. The system is to be capable of operating in either of two modes 1 waste treatment for reuse within the hospital complex, and 2 waste treatment for discharge to the environment with simultaneous water treatment, i.e., desalination of brackish water for use within the hospital complex. Quality specifications for all processed streams and design specifications for the overall system output capacity, power, weight, volume, etc. have been established by the Army. The sequence of unit processes selected for evaluation for the reuse mode was waste equalization, ultrafiltration UF, reverse osmosis RO, carbon adsorption, ozonation O3, and chlorination Cl2. Each of these unit processes except chlorination was evaluated independently, using simulated individual and composite MUST hospital wastes to determine the overall effectiveness of each and to select preferred process options and operating conditions. On the basis of these tests it was concluded that the selected sequence of unit processes, carbon adsorption excluded, appeared to be effective in producing water of reuse quality within the system design constraints.
