In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
A neutral buoyancy pool or neutral buoyancy tank is a pool of water in which neutral buoyancy is used to train astronauts for extravehicular activity and the development of procedures. These pools began to be used in the 1960s and were initially just recreational swimming pools ; dedicated facilities would later be built.
The tank is filled with 10 inches (25 cm) of water which contains enough dissolved Epsom salt to create a specific gravity of approximately 1.25–1.26, enabling a person to float freely with their face above the water. In order to reduce thermal sensations, the water in the float tank is maintained at approximately skin temperature, around 35 ...

Floatation therapy happens in a sensory deprivation tank, atop a few-inch-deep sheet of water heated to skin temperature, saturated with Epsom salt causing you to float. “I can [also] see the ...
The small bubbles adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device. Induced gas flotation is very widely used in treating the industrial wastewater effluents from oil refineries , petrochemical and chemical plants , natural gas processing plants ...
