Disposal of Aircraft Washrack Waste Water.
Abstract
The study was conducted to evaluate three different methods of treating aircraft washrack waste water, viz., dilution in an activated sludge treatment plant, filtration through a synthetic media filter, and centrifugation using both continuous-flow and batch centrifuges. Activated sludge treatment of washrack waste water from Davis-Monthan AFB was suitable at a 6-percent-by-volume dilution with domestic sewage. The chemical oxygen demand (COD) and emulsified oil concentrations at this dilution were 1000 and 200 mg/1, respectively. Coagulation of washrack waste water with alum, followed by filtration, was not economical because of the excessive chemical additions required. Centrifugation of washrack waste water was not feasible because emulsified oil removal was negligible even at relative centrifugal forces (RCF) as high as 20,000. (Author)
