However, the resulting water is still not pure water, mainly to remove the insoluble impurities in water, there are many dissolved impurities in water. To obtain high purity water needs to be prepared by distillation. Is there any faster, more efficient method of making pure water? The answer is yes. One of the more famous movies staged in the mid-1990s, he was directed by Kevin Costner, “The Future Waterworld,” one of which was a fragment: He put his own urine
