Dredge Slurry Dewatering Centrifuge

World widely, the dewatering for dredge slurry is one of the biggest obstacles for the dredge contractors. The dredge slurry dewatering system with shale shaker, desander, desilter will remove the solids above 25 microns, but for the solids below 25 microns, it require dewatering centrifuge to do the job. By mechanical separation without polymer, the GN decanter centrifuge is able to separate solids above 5 microns. With the chemical enhanced technology by decanter centrifuge separation with polymer, the zero microns separation can be reached.
For the fine and ultra-fine solids separation, there are normally two type of equipment, one is decanter centrifuge, the other is filter press. Compared to filter press, the decanter centrifuge has following advantages:

• Less polymer required by using decanter centrifuge because of it's high efficient separation capability by centrifugal force for fine solids.
• Less and easy maintenance.
• Wide application for different dredging slurry.
• More clean discharge water.
• Easy installation and less foot print by using decanter centrifuge.
• Automatic continues working with less manpower by using centrifuge for dewatering
• Saving water in flashing and cleaning of the machine.

GN Solids Control has different size of decanter centrifuge for different dredging slurry dewatering project. With our worldwide branches and partners, we have supplied our decanter centrifuge to over 40 countries in the world.
