The Pretreatment Technology Development Project is one of seven Tank Waste Remediation System (TWRS) projects being conducted at Pacific Northwest Laboratory (PNL). A key objective of this project, which includes the Tank Waste Treatment Science Task, is to provide the technical basis and scientific understanding to support TWRS baseline decisions and actions, in particular, the 1998 sludge pretreatment decision regarding the level of pretreatment to be incorporated into the tank waste process flowsheets being developed by Westinghouse Hanford Company. This report details work performed by the Tank Waste Treatment Science Task during the first quarter of FY 1995 (October--December 1994) in support of the project objective. Specific activities discussed in the main text are: analytical methods development; sludge dissolution modeling; sludge characterization studies; sludge component speciation; pretreatment chemistry evaluation; and colloidal studies for solid-liquid separations.
