Abstract

The main objective of this research was to study treatment of gaseous formaldehyde in a Gross Anatomy Laboratory (GAL) using the prototype of toxic gas purifier with ozonation. Factors affecting treatment removal efficiency include ozone dosage rate and air blower speed. Response Surface Methodology (RSM) with the Central Composite Design (CCD) model was applied to design the experimental sets and to analyze the statistical data. The optimal conditions for treatment of gaseous formaldehyde were also investigated.  Two sets of experiment were conducted in which, the first set was for case study 1 (the cadaver studied by medical students) and the second set was for case study 2 (The cadaver studied by nursing students). Results show that formaldehyde removal efficiencies received from most of experiments were relatively high (above 85%) for both case studies. Predicted removal efficiencies from the mathematical model were in good agreement with those from experimental data. The optimal conditions obtained from the CCD model were at the ozone dosage rate of 1,210 mg/hr and the air blower speed of 1.24 m/s.
