Taguchi Method Planning
Irradiation frequency, acoustic intensity, exposure time, temperature, pH, and bacterial concentration were integrated into the Taguchi method orthogonal array when planning our experiments. Data were analyzed with analysis of variance to determine the optimal combination for hydrogen production.
Factor Levels and Experimental Design
Mechanical and biological effects were considered before establishing factor levels (Table 1), which comprised two levels for temperature and three levels for the other parameters. The orthogonal array contains 12 experiments, one 2-level factor, and five 3-level factors, and can be written as ?12(2:х35). Each experiment was repeated three times.
Taguchi Data Analysis
The Taguchi method looks for key factors and levels. Because a maximized hydrogen production was desired, the Larger is Better S/N ratio in Equation (4) was regarded as optimal. At the same control factor level, the mean S/N ratio was determined for each factor at each quality objective level. Based on this, the response table was constructed and transformed to the S/N ratio response graph.
