Abstract:

The U.S. Army Biomedical Research and Development Laboratory has investigated the use of polypropylene hollow fiber crossflow filtration cartridges for treatment of shower waters for recycle. Although the membrane has a nominal pore size of 0.2 micron, consistent removals of 60-90 percent of total organic carbon TOC and better than 99 percent of turbidity have been achieved from synthetic shower water containing 50 to 100 mgL of TOC as soap. Although the system has not been optimized, a product flux of 0.5 galmin per cartridge has given best performance. Recovery of treated water has exceeded 90 percent, but considerations of health and dissolved solids buildup will probably limit recovery to 80 to 90 percent in practice.
