Vacuum distillation utilizes a simple principle. Under vacuum, water boils at a much lower temperature than 212°F (boiling temperature at normal atmosphere). This lower boiling temperature can eliminate chemical degradation that typically occurs at 212°F. The manufacturer can also recover and re-use, if desired, the large water phase (steam vapor) that has been evaporated and condensed. The re-use of the water phase is a standard alternative for all wastewater applications and is often the reason that vacuum distillation is chosen for large volume applications. A lower boiling temperature can provide significant benefit to generators with fitting applications and waste recovery objectives. During evaporation, the waste chemicals can be concentrated without destroying their chemistry, and the chemicals then can be re-used in the manufacturing process.
