Abstract
Abstract The invention relates to a system for purifying salty or brackish water which may, also, contain solids and living organisms making the water unpalatable for agriculture or long term animal consumption. The system includes a cyclic mechanism which causes an evaporable liquid to boil at a predetermined pressure and temperature in a first vertical elongated column, vapor cross over means to a second vertical elongated column, said vapor being condensed at a predetermined pressure and temperature in the second vertical elongated column, means for supplying heat to the first column, heat rejection means for the second column for reliquefying the material. Heat may be supplied to the first column by low temperature geothermal heat, heat from solar ponds, heat from solar collecting devices, as well as heat from the ambient air, or any form of low temperature heat for vaporizing the subject liquid. Heat supplied to first vertical column is always kept at a greater temperature than the second column, liquid cyclic means being provided by pump means forcing liquid in both vertical columns to the top of both vertical columns, means for venting noncondensables to the atmosphere, control means for deactivating pump means of first and second columns, gravity causes the liquid to fall in first and second vertical columns causing vaporization of the liquid in the first column and reliquefying in the second column accomplishing single stage distillation. Liquid seal means at the base of the first vertical column, liquid seal means at the base of the second vertical column. Another aspect of this invention takes advantage of cyclic relatively low pressure to degas the liquid from dangerous and hazardous dissolved gases of chlorine, arsenic, etc found in large quantities in water. Yet another aspect of the present invention is cellular destruction (DNA) of most living organisms present in the brackish water.
