Title: Precipitation Test Facility. Run 2 and Run 3. [Potassium/cesium tetraphenyl borate sluries]

Technical Report ·
OSTI ID:6707647

The Precipitation Test Facility (PTF) is the first large scale-up of the Precipitation Salt Decontamination Process developed by Lien Lee and Lester Kilpatrick of CTD. The PTF was designed to provide basic data related to the general operability of the process and effects of process variables. PTF Run 2 and PTF Run 3 were designed to demonstrate the process and to improve overall filtrate rates. PTF Run 2 used a centrifugal feed pump to transfer potassium/cesium tetraphenylborate slurries through cross-flow filters. Filtrate rates ranged from 0.02 to 0.10 gpm/ft/sup 2/ of filter area depending on slurry feed rate, slurry concentration, filtrate pressure differential, backpulsing, and operating time. PTF Run 3 was designed to examine the same variables using a low-shear diaphragm feed pump for slurry transfer. Filtrate rates improved significantly, ranging from 0.14 to 0.35 gpm/ft/sup 2/ of filter area. Optimum conditions were achieved at a slurry feed rate of 3 ft/s, a backpulse interval of 5 minutes and a filtrate differential pressure below 40 psi. 7 figures, 1 table.
