Biological dredging is the introduction and application
of naturally occurring bacteria to digest the organic portion of
the lake and wetland sediment.
It’s using nature to heal itself. The benefits are many and
the negatives are none. What could be better than that?
Bio-dredging is a win win situation for the environment.
There are two types of material found in lakes/ponds,
organic and inorganic. Inorganic materials, stone, clay and sand
are examples. Organic materials are leaves, branches, dead and decaying
matter, fish and water fowl droppings.
All of this material, organic and inorganic ends up at the bottom
of the lake/pond resulting in reducing the water volume capacity
of the lake/pond. The decaying organic material becomes the black
smelly muck layer, SLUDGE.
DSC Aquatic Solutions uses a specially formulated
combination of fatty acid digesting microbes (Bacillus strain) as
the aerobic bacteria plus purple sulfur and non-sulfur thiobacillus
for facultative anaerobic digesting microbes. The microbes are highly
efficient at assimilating a wide range of organic compounds, including
fatty acids, organic acids, primary and secondary alcohols, carbohydrates
and many aromatic compounds. The strains of bacteria will also lower
the BOD and COD as well as the suspended solids level. Our formula
contains a larvacide which reduces the larvae of water breeding
insects, flies, mosquito’s, etc.
As the lake/pond returns to normal the sludge disappears and the
water becomes clear. Nature takes over re-stabilizing the ecology.
Once the food source (sludge & pollutants) has diminished the
bacteria introduced into the water will die back to more normal
levels. The ecosystem is restored and healthy.
Bio-dredging is not only a more complete treatment
but is far less expensive than mechanical dredging. It provides
a safe, efficient and cost effective alternative to mechanical or
hydraulic dredging. Lake sediment / muck layer in most cases consists
primarily of organic material. Specific cultures of naturally occurring
bacteria are capable of digesting these organic sediments. Why transport
water and organics?
