Hydraulic dredging is one of the most efficient forms of removal and transport of dredged sediment and debris, and because all material is contained within a sealed pipeline, there is minimal impact to the surrounding community and infrastructure.
In contrast, the Dino6 Sediment Removal System is one of the safest and most effective tools for dredging a pond. It offers a perfect way to conduct pond dredging without any of the hassles associated with large excavators and hydraulic dredges.

The New Jersey Department of Transportation's Office of Maritime Resources (NJDOT/OMR) is leading, funding or participating in a variety of material management and planning initiatives throughout the state. Dredging projects have two main parts, dredging and the management of the material removed.
Dredging is a much-needed maintenance activity for reservoirs throughout the world. Barrage Maintenance. Even though typically smaller in size, barrages still require regular maintenance to ensure capacity and power generation. Ellicott's small and medium-sized cutter suction dredges are ideal for these sized projects – especially those in ...
The design of dredges varies depending on the species being targeted, but many consist of a triangular frame. A bar (with or without teeth) at the front of this frame dislodges shellfish as it is dragged over the sediment and …
Managing and regulating the disposal of dredged sediment is a shared responsibility of the EPA and the US Army Corps of Engineers (USACE), under both the Clean Water Act (CWA) and the Marine Protection, Research, and Sanctuaries Act (MPRSA or Ocean Dumping Act).

Dredge Dewatering Systems can be used with any dredging operation or waterway that needs dredged material dewatered. Ease of use - Dredge dewatering equipment is fully automated and compact, making it easy to install at your site; no cranes are needed.
Dredging projects have two main parts, dredging and the management of the material removed. Dredged material is mostly sediment that has settled into waterways through natural erosion processes. Sediment can be divided into several geologic types: sand and gravel, silt and clay and glacial till and rock. Sometimes trash, debris and …
Proven to withstand the harshest of subsea environments. The internal dredging system has been designed to be used in conjunction with either the R300 dredging system or airlift, to break up and remove hard sediment or clay soil plugs from within piles. A combination of high pressure/high flow water jets and the vacuum/suction from our R300 ...
Dredging has been a popular and effective way to remove sediment from reservoirs for decades. It can help maintain water storage volumes, improve quality of life by increasing amounts available through irrigation or drinking supplies, as well as decrease turbidity that may reduce property values near bodies of waters shorelines.
The process of sediment removal from a reservoir or a dam by mechanical or hydraulic means, as well as other methods, is known as dredging. As a result, it may be used to keep the storage capacity of future generations without causing significant drawdown. At the most basic level, dredging is the excavation of soil and rock beneath water.
Dredging means the process of removing accumulated sediment from the bottom or banks of bodies of water, including rivers, lakes or streams. Dredges are specialized pieces of equipment that create a vacuum to suck up and pump out the unwanted sediment and debris.
Mineral Technologies designs and manufactures the MD Knudsen Bowl. Specifically designed to recover gold from alluvial or hard rock deposits, upgrading and recovery of gold from concentrates from other gravity separation stages, exploration and evaluation of gold deposits,and other mineral applications including cassiterite and …
Mechanical dredging is a very old solution for removing muck, weeds, sediment, and other harmful materials from your pond. In this method, the pond should be drained completely and all aquatic life must either be relocated or killed off. A mechanical excavator can remove soil and help regain the original depth of the pond.
Dragon® Model Dredge – a trademark designation for Ellicott's exclusive line of patented, portable hydraulic pipeline cutterhead dredges, referred to as CSDs, which range in size from 10" (250 mm) to 20″ (500 mm). Dredge sizes are always expressed in terms of inside diameter of the discharge pipe. Electric Dredges – a substitute to ...
Acteon's internal dredging system is designed for the clearance of debris, sediment and soil across a range of pile sizes from subsea/submerged piles to jacket legs for both installation and decommissioning, as well as other applications. Proven to withstand the harshest of subsea environments.

Dredging – describes the digging or mining action used to collect sediment from below the water surface. The gathered sediment is then either transported elsewhere or repurposed for other uses. Horsepower Continuous Duty Rated – as the term implies, horsepower which can be supplied continuously (24 hours per day) by an engine without overheating.
Unlike hydraulic dredges, which use suction and pumping, mechanical dredges use mechanical tools like buckets to remove material from water. Their internal …
Dredges Summary Rigid structure with a chain mail collecting bag, towed on the seabed to target king scallops. Generally used by towing several dredges side by side behind the vessel. Dredges towed along the …
Dredging is the removal of sediments and debris from the bottom of lakes, rivers, harbors, and other water bodies. It is a routine necessity in waterways around the world because sedimentation—the natural …
Tidal dredging in New Hampshire is overseen by the Dredge Management Task Force (DMTF).
