An Overview of Different Distillation Technologies for Drinking Water Preparation

Abstract

Water scarcity and pollution pose critical situation in all walks of life.Among the available purification methods,desalination process proves to be a safer and more stable solution for solving this problem. This paper provides an overview of the purification effect of distillation process, along with theprinciples and research progress ofdifferent distillation techniques for small scale drinking water preparation.This paper also analyzes the advantages and disadvantages of each method, as well as proposes an outlook forthe distillation technology on drinking water preparation. This paper also indicates that the removallaw of organic pollutants, especially the volatile organic pollutants during distillation process should attract researchers' attention, whilereducing energy consumption of distillation technology through various means is still the development tendency.
