Not only for drilling application( oil & gas drilling, HDD, geothermal, CBM, water well drilling), GN equipments can be also used for mining slurry separation, dredging slurry management, piling and tunneling.

Dredging and Dewatering equipments

Dredging and Dewatering equipments

GN dredging and dewatering equipments are designed to feed slurry directly from the dredge. GN dredging slurry separation system separates solids from dredging slurry through a three phase system.

In addition, the solids that are removed are dewatered to a stackable “press filter” state, which can be readily moved with front end loader, conveyor and/or dump trucks. The effluent is pumped off by a centrifugal pump.

The separation process is continuous and operates completely mechanically without any chemical enhancement. The dredging slurry separation system is designed as a three phase separation system, 1st separation is shale shaker, 2nd separation is desander, 3rd separation is desilter. Sometimes as the client’s requirement, we only design 2 phase shale shaker and desander. The desander and desilter are made into separate mud cleaner with large screen area.

What is Dredger?

Simply speaking, Dredger (Also called dredge) isa vessel used for dredging. It is used to excavate and remove material from the bottom of a body of water. For example, a scoop attached to the end of a rope or pole by which a man can draw sediments up from the bottom of a pond is a dredger. Developing this idea further, a motorized crane equipped with a drag bucket or clamshell (grabber) that is used to scoop material from the bottom of a body of water is also a dredger. The crane could be located on the bank, or perhaps mounted on a barge. If the crane is mounted on a barge, the entire vessel is referred to as a dredger.

What is Dredging?

Dredging is an excavation activity in which materials are recovered from beneath the water’s surface. The purpose is generally to gather bottom sediment and either dispose it at a different location or use these sediments in various products, e.g. sand and gravel is used in concrete mixtures.

GN solids control design and produce dredging slurry separation system, and we cooperate with dredger manufacturer all of the world. Some of our DSS system has worked successfully in the site with dredger.

Here we listed top 5 Dredger manufacturer, welcome to contact us for more updates.
