Implementation and Analysis of Hemodialysis in the Unit Operations Laboratory


  • Sundararajan V. Madihally Oklahoma State University
  • Randy S. Lewis Brigham Young University


To enhance bioengineering in the chemical engineering curriculum, a Unit Operations experiment simulating the hemodialysis of creatinine was implemented. The blood toxin creatinine was used for developing a more realistic dialysis experiment. A dialysis model is presented that allows students to assess the validity of model assumptions. This work details the dialysis project statement delivered to the student team, the experimental protocol, the dialysis model, experimental results, and student feedback and assessment.
