Vacuum Pumps to Improve Environment

Vacuum Pumps to Improve Environment

The water flows through an oxygen-permeable membrane that is enclosed in a vacuum. The vacuum then diffuses the oxygen through the membrane, thereby removing it from the water. The liquid ring pump that generates this vacuum also bleeds off the oxygen/air mixture created by the diffusion process. Central Vacuum Cleaner Systems

Thermobaric weapon - Wikipedia

Thermobaric weapon - Wikipedia

A thermobaric weapon, aerosol bomb, or vacuum bomb is a type of explosive that uses oxygen from the surrounding air to generate a high-temperature explosion. In practice, the blast wave typically produced by such a weapon is of a significantly longer duration than that produced by a conventional condensed explosive. The fuel–air explosive (FAE) is one of the best-known types of thermobaric .
