From Introduction: "The primary objective in the development of the W. L. Badger Long Tube Vertical Multiple Effect Evaporator for saline water conversion is to minimize the ultimate cost of producing potable water. To accomplish the primary objective, it is necessary to (1) prevent formation of scale on heating surfaces, and (2) minimize corrosion to permit use of inexpensive materials of construction. The work done leading to this report was guided in the direction of accomplishing the two secondary objectives."
