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.

Sludge/Muck Layer — What is It?
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.

How Our Bio-Dredging Works
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.

Why Should You Choose Bio-Dredging?
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?

Advantages of Biological Dredging
• Environmentally neutral and safe.
• Cost is one third to one half of mechanical or hydraulic   dredging.
• Does not disturb the ecology, or cause turbidity.
• Avoids having to move the muck to another    location, microbes digest it in place.
• Avoids ramp building, and noisy equipment.
• Does not change shoreline or disturb bottom – digest   Petroleum Hydrocarbons and FOG.
• No need for settling ponds or dump sites.
• Proposal and Permitting not required.
• Engineering costs minimized, freeing funds for wetlands and   beautification.
• Produces a healthier lake.
• Decreases BOD and COD.
• Increases Dissolved Oxygen levels.
