“…In the scientific literature, RSM has been a useful tool to study the electrostatic precipitation and to predict the optimal operating conditions of this process, since it depends on several variables. Remaoun et al (2012) evaluated the performance of a one stage, wire-plate ESP collecting welding fumes, varying the width of the collecting plate (2, 4, 6, 8, and 10 cm) and the electrode spacings (2, 3, 5, and 4 cm) and obtaining a fitting model with R² of 0.89. The highest performance was obtained at the plate width of 10 cm with the electrode spacing of 3 cm.…”
