Comparison of water purification technologies considers the performances of a single and double distillation system, and a system that combines reverse osmosis, electrodeionisation and a germicidal UV
Elix UV technology compared to single and double distillation Developments in technology are closely linked to improvements in the tools made available to researchers.
In line with many other parameters, quality of the pure water used in laboratories has become highly important.
Developed centuries ago, distillation has long been the primary purification technology.
Today, newer purification technologies have proved their efficiency and robustness, and compete with distillation.
Following a brief review of the principles of the purification technologies, data are presented for the purification performances of a single and double distillation system, which combines reverse osmosis, electrodeionisation and a germicidal UV lamp.
The removal of ions, organics and bacteria are monitored using, respectively, a TOC analyser, ion chromatography and plate culture.
Maintenance procedures and energy consumption are also compared.
