The coarse shaker with a catch tank, 2 units mud agitators are installed at each side of the mud tank for better agitating. The submersible slurry pump can transfer the fluids which is discharged from coarse solids separation shaker, and feed to the next fine mesh shale shaker.
2. Fine mesh screening module, the fine mesh shale shaker and desilter mud cleaner are installed on the shaker tank, which can be divided into 2 compartments. The solids bigger than 300 microns can be separated out by the fine mesh shaker.


3. Desilter module, The fluids will drop into the mud tank under the shale shaker, then the desilter feeding pump feed the fluids to the desilter cone of the mud cleaner. The mud agitators are installed on the shaker tank. The desilter separation cut point is 15~40 microns.


4. Big bowl decanter centrifuge module, the big bowl decanter centrifuge with chemical dosing unit are installed on the telescopic skid, the mechanical separation cut point is 2~ 5 microns, with chemical dosing system, the ultra fine solids can be also separated out. The fluids catching tank under the skid can collect the centrifuge discharged fluids and a centrifugal pump can transfer the water to other tanks. The big bowl centrifuge is a 22 inch bowl and the bowl length is 71 inch, with a positive pressurized VFD control panel.
