With increased dust pollution, enforcement on air pollution regulation is expected thus bringing forth the need for a better particulate removal process. This paper capitulates on electrostatic spraying for its use in particulate matter removal. The range of appropriate voltage and solution concentration together is often referred to as the 'Stability Island'. In this study, the influence of geometric and chemical factors on the stability island is analyzed. Effect of each variable in a 8 step vertical nozzle design will be illustrated. The suitable range of nozzle geometry and solution concentration pair will be investigated.
