East Twin Lake
Michigan, United States
In this case study from Vertex Water Features, East Twin Lake, a shallow lake in Michigan, United States, had significant problems with the accumulation of organic sediment, with sludge as much as 1.8 m (6 feet) deep in some places. Aeration provided with a Vertex Air3 XL4 system removed 0.7 m (2.4 feet) of organic material in 3 years! 55.8% of the sludge and excess BOD were removed and a healthy oxygen level was restored.
