Examination of the Problem of Recuperative Treatment of Waste Water in the Chemical Industry (Consideratii Asupra Problemei Epurarii Recuperative a Apelor Reziduale din Industria Chimica)

In what follows the simplest technology -- a fractionating column having only a stripping section and heated by direct steam -- will be used to derive the general relationship among the main variables of the process of separation by fractionation and recovery of an organic substance dissolved in water. An analytical relation among these variables is established in what follows on the basis of the law obeyed by dilute solutions of organic substances (the solute) which are difficultly soluble in water (the solvent).
