Solids concentration [wt.:%]
The maximum concentration of 2.7 wt.olo was limited by the actual amount of solids present and the minimum amount of liquid necessary to run the system as it was
designed for these experiments (theoretical max. was 4.0 wt.olo). SRNL presented data of an 11.7 wt. °10 actual tank slurry in WSRC-TR-2003-00030.

Disk Fouling during operation
The O.1-fJm disk showed serious pressure fluctuations ---+ after removal of the disk material flaked off over night.
SEM-EDS analyses showed that the material flaking off the disk was mostly made of <5 fJm Na-AI silicates, AI-rich (+Cr), Ni-rich, ~-rich and Ca3(P04h-particulates.

Summary and Outlook
I. Actual tank waste from Hanford tanks show lower filtrate flux by O.3-0.6x.
II. Disk fouling during operation can be approached by running the system with 1 M nitric acid. This restores the filtrate flux to -- O.9x of original flux.
III. O.1-lJm disk has no apparent advantage over O.5-~m disk; same filtrate clarity, but lower flux rates => not recommended for Hanford tank waste
The single disk model of the 5pinTek filtration unit in 1-F of the 222-5 laboratory is ready for any future tests.
(e.g., new filter materials or different feed slurries)

Principle of Filtration in the SpinTek system (backup slide)
Promoters, shaped like wagon wheels, induce the turbulence needed to prevent rotational flow ~ reduced filter fouling
Calculation of temperature adjusted filtrate fluxes (backup slide)
For better comparison between the different test groups, all filtrate fluxes were corrected to 35°C (= 95 OF = 308.15 K). Temperature corrected fluxes were
calculated using the equation:
F _ 2500( 1 - 1 J 35C - ~riginal_flux • e T+273.15 308.15
