Abstract : Various nitrocellulose (NC) manufacturing processes at Radford Army Ammunition Plant (PAAP), VA produce wastewater containing NC particles in millimeter, micron, and sub-micron range, known as 'fines.' Available NC fines characterization data vary widely and often conflict with each other because they are based on 'grab samples,' in which the wastewater quality can fluctuate widely. A critical need exists to collect and analyze NC fines characteristics at each sequence for each unit operation over an extended period of time. The U.S. Army Construction Engineering Research Laboratories (USACERL) has been evaluating technical alternatives and developing technologies to separate, recycle, and treat NC fines from RAAP manufacturing wastewater. This study characterized the physical properties of NC fines and developed a strategy to prevent pollution with NC fines. Characterized parameters included particle size distribution (PSD), total suspended solids (TSS), turbidity, zeta potential (particle surface charge), conductivity, and pH. Recommended pollution prevention methods included separation and recycle of NC fines at each process, more effective settling, and in-process modifications.
