GN Hydrovac Slurry Dewatering System In North America
GN Solids Control made hydrovac slurry systems are widely used in many countries, with more and more hydrovac contractors pay great attention to the environmental protection regulations, there is a increasing demands of hydrovac slurry dewatering system.
GN Solids Control has provided hydrovac slurry dewatering systems since 2017, with these years fast development, GN made hydrovac slurry system become the most cost-effective solution in this market.
Today we’d like to share some details of another GN hydrovac slurry dewatering system running in North America. Here are the main GN components in this system:
1.GN Catch Hopper
GN catch hopper collects the hydrovac truck dumped slurry, with large metal crossings fixed on the top of the hopper to hold the big stones fall into the shaker from damaging.
2.GN Coarse Shaker
GN coarse shaker uses opening mesh screens, heavy capacity slurry are treated in this long deck shaker, and all aggregates are removed.
3.GN Double Deck Shaker
A submersible pump feed the slurry after treated by GN coarse shaker into GN double deck shaker GNZS706. Two layers screens work effectively to remove different solids out. By using Hi-G force shaker, GN double deck shaker is able to remove solids large than 100 microns, which usually sands are recovered.
12 pcs GN 4 inch cyclones are fixed on GN 4 panels shaker and compose one GNZJ594-12N. Solids larger than 25 microns are removed, which are usually classified as sand and silts.
5.GN Decanter Centrifuge
GN 22 inch bowl decanter centrifuge GNLW553C-VFD is fixed on the telescopic skid, rotating under larger G force, finest solids here are silts are recovered. A screw pump is used to feed the slurry into GN decanter centrifuge.
6.GN Chemical Dosing Unit
GN 3 compartments chemical dosing unit provide flocculant automatically and continuously into GN decanter centrifuge. Help even finer particles gathered and can be removed in GN decanter centrifuge.
7.GN Mud Tank
To storage and mix the hydrovac slurry, GN Solids Control provides several mud tanks with mixing line, water flushing ling and jetting line.
