| The Technological Advantage of Steam Distillation |
|
Steam-distillation is the only treatment process that first boils the raw water and then condenses the pure steam to form very high purity water. ![]() Nature's Hydrologic Cycle; the non-barrier solar thermal cycle which produces pure rainwater 1 Evaporation
![]() Steam Distillation system utlizes the same non-barrier thermal cycle. Barrier Methods of Water Purification Traditional barrier methods of water purification (various filters and reverse osmosis) consist of a physical "barrier" placed into the water stream. This barrier, held in place with o-rings and seals, removes the contaminants from the raw water and only allows "filtered water" through. ![]() Raw water containing contaminants meet the barrier which is designed to remove certain contaminants and allow "filtered-water" through. The contaminants can either build up at, or in the barrier or some can be "back-washed" and flushed down the drain. Superiority of Steam Distillation in an Emergency or Bio-terrorist Attack on Water Supplies In the event of an emergency or a bio-terrorism attack on the water supplies, the water, the incoming pipes, and the barrier will all become contaminated. The barrier will be rendered useless, and, assuming there is awareness of the attack, the water line would be shut down. In the event the attack has gone unnoticed, people will drink water passing through a contaminated barrier.
Biological agents are injected into the water and contaminate pipes. Some biological agents may migrate through the barrier through fissures, channels or around seals, and into the product water. ![]() As a result, the barrier itself is rendered unusable. Steam Distillation Method Where a steam-distillation system has been installed, the water, incoming water line, and the water in the boiling chamber will become contaminated, but the steam-distilled water will be safe to drink. Steam distillation has three distinct advantages over barrier methods.
