Recently GN solids control shipped several sets of mud cleaning system to our North America client, this is for their repeat orders for vacuum truck slurry/mud cleaning system. The technical configuration of the mud cleaning system is as below:
1) Slurry collection hopper which is installed on top of the slurry treatment system, in the previous design the slurry collection hopper is laying separately, considering the area limit at client’s working site, we put the slurry collection hopper on top of the mud cleaning tank to save space. There is discharge port under the collection hopper to feed directly to the 2 units of dual deck shale shaker.
2) The coarse solids separation tank including 2 units of dual deck shale shaker and 1 unit of mud agitator. The shaker screens installed is with coarse mesh size, so that coarse solids can be separated out in this process.
3) The fine solids separation tank including 1 unit of linear motion shale shaker with fine wire mesh to separate the fine solids from the slurry, the submersible slurry pump transfer the clean mud to the mud cleaner, the desilter cone separation cut point is 25 microns. The outter protection guard is desgined for HSE purpose according to client’s feedback.
4) The clean mud discharged from mud cleaner will be transferred to dewatering centrifuge system to separate ultra fine solids up to 1 microns. The dewatering centrifuge is a big bowl big volume decanter centrifuge with VFD control panel, to increase the separation efficiency and get drier discharged solids, chemical dosing system will be used before feeding to the dewatering centrifuge.
The discharged solids will be reused for construction industry, the recovered fluids can be also used in the process. For more information of the system, pls contact with GN solids sales.
