INTRODUCTION
Radford Army Ammunition Plant (RAAP), like most of the Army propellant and
explosive manufacturing plants, was built in the early 1940s to supply munitions for
World War II. In 1970, the Army initiated modernization programs at its ammunition
plants to replace obsolete facilities and improve the safety of operations. As part of this
modernization program a Continuous Automated Multi-Base Line (CAMBL) manufacturing facility is planned for construction at RAAP to augment the present labor intensive
batch process. This paper describes the studies that were conducted to develop design
criteria for a facility to treat the wastewaters that will be generated in the CAMBL.
WASTEWATER CHARACTERIZATION
A wastewater characterization study was conducted for the CAMBL manufacturing
facilities. Samples of the wastewaters were collected and analyzed during the evaluation
of a prototype CAMBL manufacturing line. These data were compiled, and the expected
characterization of the full-scale facilities were determined. The quantity of water requiring treatment from the CAMBL facility was determined to be approximately 50,000
gal/day. This wastewater wiU contain acetone, ethanol, nitroglycerin (NG), nitroguanidine
(NGu), other propellant ingredients and inorganic nitrates.
LABORATORY TREATMENT STUDIES
Laboratory-scale treatment studies were conducted to determine the feasibility of
selected treatment methods and to define the design parameters for pilot plant studies.
Studies were conducted for the removal of suspended solids by using catch basins containing screens and bag filters. The removal efficiency of various size screens and filter
bags was determined. These studies showed that a 80-mesh screen would retain 60-70%
and a 25-(i filter bag retained over 95% of the suspended solids (see Figure 1).
