Abstract:

A pilot-scale vacuum membrane distillation (VMD) demonstration plant for decontamination of radioactive wastewater with 8.0 m3/d water production was developed. The design scheme, main components and functions of VMD pilot plant were detailed. Effects of operational parameters on permeate flux, gain output ratio (GOR) and decontamination factor (DF) of simulated radioactive wastewater were analyzed. As feed temperature increased from 70 to 90, permeate flux grew exponentially from 1.59 kg/(m2·h) to 6.82 kg/(m2·h). High DF 104.85 of Cs+ and high concentration factor (CF) 110.3 of simulated radioactive wastewater were reached with stable permeate flux in pilot-plant-scale. DF of Cs+ and GOR were relatively stable under various operation conditions. The outlet temperature of membrane modules increased with the growth of flow rate, bringing about 9 °C temperature difference between 2 m3/h and 14 m3/h at the same inlet temperature of 70 °C. The significant heat loss in radial direction as temperature polarization and in axial direction as the heat pinch effect in hollow fiber membrane modules are the main issues for large-scale MD plant. This study demonstrates a remarkable potential of VMD for decontamination of radioactive wastewater and provides an integrated design of VMD pilot-scale plant. © 2021 Elsevier B.V.
