CNRC - Canadian National Research Council paper on  

Wastewater Treatment with Windmill Aeration.

Aeration facilitates wastewater treatment in a facultative lagoon by changing the bacterial popula­tion, which in turn, should speed up the process of reduction of BOD and suspended solids.


The aeration is provided by the installation of windmill-powered aeration systems into a primary lagoon cell. This added aeration increases the dissolved oxygen, enhancing microbial activity and improving the efficiency of the wastewater and sludge treatment. Increased aeration causes the bac­terial community structure to shift from anaerobic and facultative to aerobic groups. 

These aerobic micro-organisms speed up the treatment process, reducing the Biological Oxygen Demand (BOD), Total Suspended Solids (TSS) and nutrient levels, and reducing the loading  of potential contaminants to the environment.
