【 摘 要 】

The objectives of this test were: determine the optimum filter operating parameters to maximize filter flux; determine whether the mean filter flux across the dewatering cycle matches or exceeds the plant design throughput; dewater the feed sample to 20 wt percentage insoluble solids; wash the sample to determine which species are removed during the washing process; provide filtrate to the ion exchange test program; the project flowsheet for the separation of LAW entrained solids assumes the entrained solids slurry from ultrafiltration contains 20 wt percentage insoluble solids by weight. These tests must therefore confirm that the slurry rheology is compatible with this requirement. No solids must pass into the ultrafiltration permeate; and after the filtration stage is complete, the rig will be chemically cleaned to determine if the clean water flux can be returned to pre-operation (clean) levels.
