Waste to water: a low energy water distillation method Original Research Article

This paper describes a new water distillation method and apparatus. It is a low-cost system operating at low temperature and sub-atmospheric pressure that can produce water at different scales, for large cities or remote rural communities, thus suitable for the First World or the Third. The system may be configured to use waste heat from power plants, allowing co-generation of fresh water and with electricity. Though using waste heat allows for water production efficiency which is better than the current leading technologies, the process can also be made to run with other sources of low quality heat and alternative energy sources.
