The most effective pump type for one stage may underperform elsewhere; selection should reflect the actual operating context rather than applying a single solution site-wide.Tailings transfer: Horizontal pump for high flow and continuous operationMine sump dewatering: Vertical pump handles fluctuating solidsRemote pit dredging: Submersible pump provides direct slurry ...
Introduction Offshore dredging projects represent one of the most complex challenges in marine engineering. ...
Introduction Dredging is a fundamental activity to ensure port navigability, sediment management, and the hydraulic safety of rivers, canals, and artificial basins. ...
This placement drives priming behavior, suction limitations, solids handling, maintenance accessibility, and overall system design in real world conditions such as slurry handling, dewatering, dredging, mining, and industrial transfers. The comparison below focuses on performance under load, typical application fit, and how system constraints drive the choice. ...
It is typically defined by production targets such as dredging output, solids transfer rate, or process throughput. Flow rate cannot be evaluated on volume alone; it must maintain enough pipeline velocity to keep solids suspended. ...
Integrated Restoration Strategy Winter 2025 dredging removed approximately 6,000 cubic yards of accumulated sediment from the pond's cut area. ...
By locating the pump below the fluid surface, air entrainment and loss of prime are avoided, and solids pickup is improved compared with dry-mounted systems. Submersible variants include dredge pumps used for sediment removal and excavation tasks, while a sand pump typically refers to applications involving high volumes of abrasive granular material.What Is a Submersible Slurry ...
In pontoon dredging, the gap between test-based pump curves and field results is a common source of underperformance. ...
In a major effort to protect human and environmental health, EPA works with its state, federal and tribal regulatory partners to monitor and ensure compliance with clean water laws and regulations. The Clean Water Act (CWA) is the principal federal law that governs water ...

.): Short-term sediment containment around construction or dredging works in rivers, lakes, harbours or coastal waters Creating a quiescent zone so disturbed sediment settles before water leaves the work area Turbidity curtains typically have permeable or semi-permeable skirts and are anchored as temporary perimeter barriers in open water (Chatoyer Environmental n.d.). ...
The ponds were about 30 years old, not aerated, and have never been dredged or treated to remove ...
The growth of maritime traffic in Portuguese-speaking African countries has made dredging a strategic element for the competitiveness of commercial ports, industrial terminals, and large rivers. Keeping the seabed at the correct depth means guaranteeing access to deeper draft vessels, reducing logistics costs along inland corridors, and creating new opportunities for businesses ...
Introduction: why energy efficiency in dredging is crucial today In the modern industrial context, energy efficiency has become a determining factor in the design and management of dredging projects. ...
Introduction In the industrial dredging sector, each project presents unique operating conditions: material density, working depth, site accessibility, and productivity goals. ...
1. Introduction Dredging is a fundamental practice to keep ports, canals, and industrial basins navigable. ...
1. Introduction Modular dredging systems represent one of the most significant evolutions in the sector. They allow you to combine flexibility, logistical efficiency, and high performance, adapting to various operational contexts: from mining dredging to port maintenance, up to environmental reclamation projects. ...
Introduction With the growing global demand for critical raw materials and the need to explore untapped deposits on the seabed, the underwater mining sector is experiencing a major technological acceleration. Traditional equipment is no longer enough. We need robust, smart, and remote solutions capable of operating at increasing depths. In this article, we examine the main innovations, the ...
Introduction Dredging is a key activity for maintaining and expanding Brazilian ports. Brazil relies on a strategic maritime network for global trade and faces a growing need for modern infrastructure. Portable dredging systems, like the new generation of compact and modular dredges, offer an effective and flexible solution to tackle sediment ...
Introduction Colombia has high development potential for industrial, mining, and port dredging in South America. The mix of vast natural resources, growing infrastructure, and environmental awareness makes the country a strategic market for advanced slurry and abrasive material pumping technology. ...
