Why Turbine Aeration
Why VaraCorp Air Turbine?
All things considered, the VaraCorp aerator has proven itself to outlast and outperform virtually every aerator in its class in the market today.
VaraCorp’s air turbine uses the twin physics principles of precession (as applied to rotating fluids) and centrifugal force. Precession creates the low pressure zone which draws in the surface air. Once inside the turbine chamber, this air is discharged rapidly through the power of centrifugal force. There are two important factors that further distinguish VaraCorp’s turbine aerator. First, the centrifugal force slings the air outward at a high speed in a lateral direction. See Videos on Home page. Second, tests in a clear water tank have shown that the dissolved oxygen is also pushed downward up to ten feet below the surface. These forces create a mixing and sheering action which produce and disperse microbubbles. The air turbine offers a gross air transfer volume up to 76 cubic feet per minute.
1. Oxygen Transfer Efficiency
The ability of any aerator to transfer dissolved oxygen into a body of water is of key importance when comparing aerators. Other keys are the initial capital cost of the aerator plus its ongoing costs such as maintenance, repair, and electrical power consumption. Since the primary concern of most clients is the transfer efficiency, this issue is discussed in the report referenced below.
VaraCorp’s Air Turbine can transfer 4.7 pounds of dissolved oxygen per horsepower hour per field study. This equates to 450 pounds of dissolved oxygen per/unit/day.
2. Power Consumption Efficiency
By some estimates the monthly cost of powering the aeration system can be as much as 60% of the cost of running the entire treatment system. If this is the case, then the primary focus needs to be placed on meeting treatment goals while minimizing power consumption. The five-horsepower VaraCorp aeration system has often been selected by potential clients largely on its ability to aerate a lagoon at a fraction of the monthly electrical cost of competing systems. In at least one client case the VaraCorp aerator increased dissolved oxygen levels while reducing electrical costs over 50%.
