Abstract
PURPOSE: To obtain distilled water containing no metal salts practically by preventing the evaporation of salts by the distillation at ordinary pressure of waste water containing the salts of such metals as chromium, copper, etc., in a specific still wall- contact temperature range.
CONSTITUTION: A waste water containing metal salts, e.g., chrome-, copper-, and nickel-plating waste waters, etc., is regulated its pH to 6 to 8 and then subjected to an ordinary pressure-distillation at a still wall-contact temperature of 90W110°C. Thus, because the evaporation of metal salts is made impossible, the separation of practically metal salts-free good quality distilled water from enriched metal salts solution can be attained, and the separated distilled water can be reused.
