WATER RECOVERY FROM HUMAN LIQUID WASTES BY DISTILLATION AND CHEMICAL OXIDATION.
Abstract
The recovery of potable water from human urine by atmospheric and vacuum distillation and by chemical oxidation was investigated, utilizing the parameters of organic carbon, biochemical oxygen demand, and chemical oxygen demand. Linear relationships existed between organic carbon, BOD, and COD for the human urine samples studied. The ratio of organic carbon to BOD equaled 1.34; that of BOD to COD equaled 0.52; and that of organic carbon to COD equaled 0.64. The vacuum distillation of urine yielded a water suitable for human consumption. The chemical oxidation of human urine by ozonation was not found to be a practical means of treatment and water recovery because of the excessive quantities of ozone required. (Author)
