Late Washing efficiency
Interim Waste Technology has demonstrated the Late Washing concept on the Experimental Laboratory Filter (ELF) at TNX. In two tests, washing reduced the [NO{sub 2}{sup {minus}}] from 0.08 M to approximately 0.01 M on slurries with 2 year equivalent radiation exposures and 9.5 wt. % solids. For both washes, the [NO{sub 2}{sup {minus}}] decreased at rates near theoretical for a constant volume stirred vessel, indicating approximately l00% washing efficiency. Permeate flux was greater than 0.05 gpm/ft{sup 2} for both washes at a transmembrane pressure of 50 psi and flow velocity of 9 ft/sec.
