If you are thinking of doing any construction or work within the vicinity of an oil platform or seafloor you should definitely look into the uses of a dissolved air flotation plant. These are floating devices that are capable of storing air bubbles and moving them to areas of high concentration of dissolved air. This can be used on a variety of projects including the extraction of heavy sediments from the ocean floor, offshore rigs, and even out at sea. They are also very effective in a variety of environments where the air density is very low; this means that you do not have to use the same type of compressed air that you would find in other types of applications. With such low pressures and densities, the air that these units hold can travel long distances with no problems, and because they are also capable of storing large volumes of air they can also be used as supplemental support for the floating platforms during booms.
The basic design of a typical dissolved air flotation plant is one or more large tanks with an air source that is stored in a reservoir on the bottom of the unit. As the bubbles travel up the tanks a current is used to assist them in their travel; this current is usually provided by an electric motor. When the bubbles reach the higher levels of the atmosphere they are quickly replaced by fresh air. The pressure inside the tank is sufficient to keep the air in the bubbles in place when the traveling current is not strong enough to push them out. The added support that the air provides as it is pushed out of the way by the buoyancy of the tank itself greatly increases the efficiency of these units.
There are a wide variety of different sized tanks available to house one of these units, and one of the most common sizes is the 15-gallon holding tank. You can also find units that hold up to ten gallons of liquid at a time. Another important consideration is the availability of electrical power for the system. If the local electric company does not provide you with enough outlets to handle the load, the dissolved air flotation plant may need to be connected to a battery to be plugged into. The amount of liquid in the holding tank is also another factor to consider because you do not want to be filling the tank to the top before it is even empty.
