  • Mechanical Dredging Vs. Biological Dredging

    For many years, mechanical dredging has been the solution for dying ponds, lakes, retention basins, and rivers. Dredging removes sediment, some excess nutrients, pollutants and organic matter. By increasing the depth in this way, weed growth is discouraged, water temperature lowered and oxygen levels may be increased. Although mechanical dredging can help in these ways, it only solves part of the ...

Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...
