Problems solved by technology

Thermal distillation systems often rely on vacuum to increase water recovery by extracting increasing steam using a given amount of thermal energy; however, vacuum systems in large-scale systems can become troublesome due to leaks and require mechanical reinforcement
Thermal systems also rely on heat exchangers to recover some heat of condensation, but heat exchangers are prone to clogging and fouling and require frequent maintenance

Abstract

Embodiments of the present invention provide a system and method for water purification and desalination. The system includes a preheater, degasser, multiple evaporation chambers with demisters, heat pipes, and a control system that enables continuous operation of the purification and desalination system without user intervention or cleaning. The system recovers heat from each evaporation stage while simultaneously removing a variety of contaminants from contaminated water samples, including microbial contaminants, radioactive contaminants, metals, salts, volatile organic compounds, and non-volatile organic compounds.

Description

[0001] This application claims priority to US Provisional Patent Application No. 61 / 097,835, filed September 17, 2008, and the entire disclosure of that application is incorporated herein by reference. The invention relates to the field of water purification and desalination. In particular, embodiments of the invention relate to systems and methods for removing substantially all of a wide variety of impurities from water using automated procedures that require minimal cleaning or maintenance over a period of months to years, And it produces relatively high product water per unit of input water with ultra-low energy requirements. Background technique [0002] Water purification technologies are fast becoming an essential aspect of modern life as traditional water sources are increasingly scarce, municipal distribution systems for drinking water are declining over time, and increasing water usage depletes wells and reservoirs, causing Saltwater contamination. In addition, many...
