Malvern Insitec-S instruments were used to measure the size distribution and volume concentration of the aerosol. The total spray volume was calculated using differential mass and flow measurements. Measure the pressure and flow in the piping. Met: The pressure and flow in the piping were measured and recorded with a data acquisition system. Characterize the viscosity or rheology, particle size distribution, bulk density, and surface tension of each simulant tested. Met: The simulants tested were characterized prior to testing and in many cases after testing (Chapter 4). Calculate the test chamber volume from internal dimensions. Met: The volume of the test chamber was calculated using the AutoCAD software and as-built measurements. v S.3 Quality Requirements The Pacific Northwest National Laboratory (PNNL) Quality Assurance (QA) Program is based on the requirements defined in the DOE Order 414.1D, Quality Assurance, and 10 CFR 830, Energy/Nuclear Safety Management, and Subpart A-Quality Assurance Requirements (a.k.a., the Quality Rule). PNNL has chosen to implement the following consensus standards in a graded approach:

SummaryThis document completes the requirements of Milestone 1-2, PNNL Draft Literature Review, discussed in the scope of work outlined in the EM-31 Support Project task plan WP-2.3.6-2010-1. The focus of task WP-2.3.6 is to improve the U.S. Department of Energy's (DOE's) understanding of filtration operations for high-level waste (HLW) to enhance filtration and cleaning efficiencies, thereby increasing process throughput and reducing the sodium demand (through acid neutralization). Developing the processes for fulfilling the cleaning/backpulsing requirements will result in more efficient operations for both the Hanford Tank Waste Treatment and Immobilization Plant (WTP) and the Savannah River Site (SRS), thereby increasing throughput by limiting cleaning cycles.The purpose of this document is to summarize Pacific Northwest National Laboratory's (PNNL's) literature review of historical filtration testing at the laboratory and of testing found in peer-reviewed journals. Eventually, the contents of this document will be merged with a literature review by SRS to produce a summary report for DOE of the results of previous filtration testing at the laboratories and the types of testing that still need to be completed to address the questions about improved filtration performance at WTP and SRS. To this end, this report presents 1) a review of the current state of crossflow filtration knowledge available in the peer-reviewed literature, 2) a detailed review of PNNLrelated filtration studies specific to the Hanford site, and 3) an overview of current waste filtration models developed by PNNL and suggested avenues for future model development.This extensive review provides a starting point to help achieve the ultimate goal of the current project, which is to identify technologies such as modifications to the process (e.g., reconfiguration of the filter geometry or changes to operational techniques) or the use of physical property modifiers that increase the sustainability of the filter process. Overall, two avenues of future model development are recommended: 1) determination of long-term filtration dynamics of actual waste and waste simulant slurries and 2) evaluation of the impact of solution chemistry on the rate of filtration and filter fouling. A better understanding of these long-term fouling dynamics and solution chemistry effects will help in developing better predictive models and improved process optimization.v
