Paper Title:
The Regenerative Experiment of Activated Alumina Granules
  Abstract

Activated alumina granules is a primary sorption media . The intention of this experiment is to get out of the difference between the different regenerate medias, caustic soda and alumina sulfate . Experimental result shows the renewal adsorption capacity of activated alumina using caustic soda regenerate is more than using aluminum sulfate .Under the same experiment condition ,aluminum sulfate can regain 13.27mg/g adsorption capacity while using 0.8 per cent caustic soda to regenerate alumina and 5.36mg/g using 4 per cent aluminum sulfate .The intensity of activated alumina granules reduces when we use caustic soda as regenerate media .The mass wastage of activated alumina granules is between 12% and 14% using caustic soda as regenerate media and between 6% and 8%uing aluminum sulfate .It is needed to neutralized by hydrochloric acid or aluminum sulfate after regenerated by caustic soda .Without neutralized, the concentration of treated water is over 1.0mg/l in the beginning.And neutralized with hydrochloric acid or aluminum sulfate, the efficacious run time can achieve 23 hours and 31hours .
