Erosion & sediment control solutions for soil remediation

by Erosion Control Forum     based in Bend, OREGON (USA)

REMEDIAL ACTION PRACTICES include the requirements to develop erosion and sedimentation control plans, specifying plan content and soil conservation measures to keep sediment–laden mud from washing into storm sewers and watersheds where debris can clog creek channels and choke off aquatic life. Sediment control BMPs combine structural and non–structural measures used to avoid or minimize pollutants accumulated by environmental hazards across impervious surfaces.

Automated solutions for the marina dredge and canal dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

The 8” Swinging Ladder Dredge is ideal for channels, rivers, marinas, lakes, and canals where maneuverability and wider cuts improve productivity. The 8” Swinging Dragon Dredge uses an 8” x 8” high chrome, hull mounted dredging pump for wear resistant, efficient pumping. The dredge can cut a maximum path of up to 22’ wide allowing the dredge to cut a wider path than most one truck transportable dredges.

Automated solutions for the environmental remediation dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

LWT’s dredging systems are used for environmental remediation and cleanup. The automated dredging systems from LWT can handle the toughest contaminated sludge and keep operators safe with radio remote operation. Bio-degradable hydraulic oil used in the dredges eliminates any environmental hazards.

Automated solutions for the power plant inlet water dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

Liquid Waste Technology’s dredging systems are used for power plant cooling water dredge applications. LWT’s dredges are designed to remove the sand, silt and sediment that build up in reception ponds and inlet channels to power plants. Each dredging system is custom built for the inlet water application, including the level of automation, removal rate and dredging depth required for each job.

Automated solutions for the industrial lagoon / pond dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

Liquid Waste Technology’s dredging systems are widely used for industrial lagoon dredging applications. Electric driven or diesel engine driven dredges are used for removing mine tailings, dredging chemical processing waste ponds, and slag recovery. Automation can be added to make dredging industrial lagoons more efficient and productive.

SONARtrac - Dredging - Hopper Vessels

by CiDRA     based in Wallingford, CONNECTICUT (USA)

Soil density, hardness, lithology, and sediment particle size distribution can create slurry of variable makeup and density. At a constant pump speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sand outs in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flow meters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements. In addition, the presence of entrained gases may disturb the readings of traditional flowmeters and cause slurry density measurements to be inaccurate.

Automated solutions for the municipal sludge recycling using dredges

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

LWT`s dredging systems can be used for municipal sludge recycling applications. Sludge is mixed with compost and used in nurseries, sod farms, and agricultural applications.

Automated solutions for the environmental cleanup dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

Environmental cleanup is an important application for LWT dredges. Mud Cat and Pit Hog dredges are used for chemical and biological cleanup in harbors, rivers and lakes. The patented auger shroud on the Mud Cat dredges minimizes turbidity, and entraps suspended material for suction efficiency. LWT’s automated controls and instrumentation allows the operators to assess real time performance of the dredge technology.

Odor Control for Refining

by OMI Industries (OMI)     based in Long Grove, ILLINOIS (USA)

You Refine The Fuel, We’ll Remove The Odors

Oil refineries and petrochemical plants may generate large volumes of odor from the processing and refining of different fuels. Sulfides, mercaptans, and hydrocarbon compounds are all closely related to the oil industry. The odors generated from these industrial compounds are of a high nuisance value and generally create concern among local air boards and the public.

Automated solutions for the hazardous waste pit dredging

by Liquid Waste Technology LLC (LWT LLC)     based in New Richmond, WISCONSIN (USA)

Liquid Waste Technology’s electric and diesel driven dredges can improve safety for workers dredging hazardous materials. Our custom built dredges can be equipped with remote control to allow workers to stand up to 762 meters (2500 feet) away from the toxic area, increasing their safety. Liquid Waste Technology can build dredges with automated controls, that dredge entire ponds using PLC controls. This increases workers safety and productivity in hazardous dredging applications.

SONARtrac - Dredging - Cutter Vessels

by CiDRA     based in Wallingford, CONNECTICUT (USA)

Cutting efficiency is greatly affected by variability in soil density, hardness, lithology, and sediment particle size distribution. All of these factors create slurry of variable makeup and density. If the dredge pump works at a constant speed, the slurry will have a variable flow velocity, which is undesirable and potentially dangerous. If the velocity is too low, there is a risk of sandouts in the pipeline. If the velocity is too high, the pump will wear and be inefficient. Traditional velocity flowmeters with wetted parts are prone to wear, causing measurement inaccuracies, and require frequent, costly replacements

Monitor Dredging Slurry Flow

by Greyline Instruments Inc.     based in Long Sault, ONTARIO (CANADA)

Thousands of dredges are operated to maintain navigation channels in our rivers, lakes and harbours and to mine sand and gravel for the construction industry. Managing and optimizing production from a dredge requires continuous monitoring of pipeline pressure, vacuum and slurry velocity. The operating conditions are extremely harsh and any sensing components in contact with the abrasive slurry can be damaged. But dredge operators need accurate real-time flow information to properly manage production so equipment manufacturers have been seeking innovative monitoring solutions...
