ABSTRACT
Electrostatics is found at the basis of many major industries related to environment preservation, communications, processing of mineral ore resources, and so on. In the majority of these industries, the unique properties of high-voltage electrostatic fields and forces are utilized to collect, direct, deposit, separate, or select very small or lightweight particles. The chapter discusses the principles of application of electrostatics for the following selected industries: electrostatic precipitation, electrostatic separation, electrostatic painting, electrostatic spraying of pesticides in orchards, electrostatic imaging, and electrostatic printing, etc. In high-voltage power equipment, the current-carrying components must be cooled to carry away the heat caused by ohmic losses. A more effective method in coolant circulation is based on the force transmitted to the cooling fluid by charges in a high-voltage field. When a pulsed electric field of moderate magnitude is applied, a cell membrane breaks down and becomes permeable, but a resealing process follows due to the fluidity of the membrane.
