Aquaculture / Fish farming
The aquaculture industry uses blowers and compressors in a variety of different ways. They can be employed to maintain water quality, supply feeding systems, create bubble curtains, or to move stocks within the farm. Many of these processes require a blower that can provide pure, oil-free air.
Pneumatic conveying is used in many manufacturing processes to transport dry bulk materials or powders through a pipeline. Find out more.
Aerobic wastewater treatment plants use millions of living bacteria and microorganisms to treat organic waste, breaking it down into carbon dioxide, nitrogen, and clean water. These bacteria need a reliable and steady flow of oxygen to survive. The aeration tanks are supplied with this clean air through continuous blower operation.
Flue gas desulfurization
Without the appropriate system in place, coal-fired power plants release harmful sulfur dioxide into the atmosphere. However, blowers can be used to remove it from the exhaust flue gases, reducing emissions and helping meet local standards for emission reduction. Blowers for this application are in operation around the clock, requiring machines that can operate with virtually zero downtime and a reliable, constant air supply.
Blowers work by increasing air pressure. The exact operating principle depends on the type of blower. A side channel blower transfers the kinetic energy of a rotating impeller to the air or gas and converts it into pressure. A rotary lobe blower operates differently. Two three-bladed lobes operate in opposite directions. The rotation of the lobes traps the air or gas, compresses it, and transports it to the next stage or the outlet.
Aeration blowers are used in wastewater treatment. They provide aeration to promote aerobic digestion and keep solids suspended in activated sludge tanks. There is no specific blower technology used for aeration: the name refers only to the blower application.
Industrial blowers are machines that provide a large flow of air or gas for a specific industrial application. This air is at a slightly higher pressure than ambient air and is concentrated in one specific direction. This name refers to the application, not a specific blower technology.
Both fans and blowers circulate air. A fan moves air or gas with a very low increase in pressure, and usually circulates air throughout a wide area, such as a room. A blower, on the other hand, concentrates the air flow in one specific direction at a slightly higher pressure.
While both a compressor and a blower create overpressure, they use different methods and give different results. A blower uses a slight increase in pressure to push the gas in a certain direction. A compressor raises the pressure of the gas by compressing it into a small space, making it denser.
The difference is in the pressure. A blower is used when overpressure is needed (blowing), whereas a vacuum pump is used when suction is required.
Leaf blowers and industrial blowers work on the same principle and use the same technology – only the way they are installed is different. Industrial and aeration blowers are permanently installed industrial equipment and may use any form of blower technology. A leaf blower is a type of centrifugal blower that has been specifically designed to move leaves in a garden or public space. It must therefore be portable, reasonably light, and simple to use.
