Dewatering unit main contains chemical treatment to allow decanter centrifuge get a better separation point . The chemicals will help suspended solids and fine solids gather together , so that decanter centrifuge can separate them out by centrifugal force .

Main Working Procedure For Dewatering Unit

1. Put flocculant into hopper and keep sure there are enough flocculant all the time .
2. Open water inlet and start auger to pre-mix flocculant , there will be water enter first compartment of mixing tank while pre-mixed flocculant drop into tank for mix , one set agitator installed to help .
3. Flocculant fluids will over flow to second compartment to allow it keep more than 30 minutes before goes into decanter centrifuge . While the flocculant fluids get more and more, it will over flow into third compartment .
4. There is one or two pump suction from third compartment and feed into decanter centrifuge .
5. There will be another pump supply mud to decanter centrifuge while flocculant fluids be pumping into centrifuge , there will be a pipe for flocculant fluids and mud pre-mix to gather solids particals . The solids out of centrifuge will be keep in a cuttings box and fluids part can be reused .
6. There is another part for chemicals mix which is a plastic tank with a small agitator for easy mix particals . Open water inlet and put correct qty of chemicals into tank , it will be mixed soon and then can be delivery into centrifuge by another pump .

Because of the chemical fuctions , the main solids particals will be separated out and product will be very clean and can be re-use on drilling site . Normally we will choose a high speed decanter centrifuge for the job as there are several options infact . Please contact GN Solids freely for more information .

China Petroleum Pipeline Bureau with name China CPP for short, they purchased 500 GPM mud recycling system with and or without decanter centrifuge . The original purchase of 500 GPM mud system from China CPP is one tank 500 GPM mud system with one set linear motion shale shaker and one set liner motion mud cleaner to reach 500 GPM mud flow . But this time, they ordered 1000 GPM mud flow with 2 set decanter centrifuge and 2 sets double deck shale shaker .

Main Introduction Of 1000 GPM Mud System For China CPP

There are 2 mud tanks totally , the first mud tank will install one set linear motion double deck shale shaker with 2 sets desander cones and one set linear motion double deck shale shaker with 12 sets desilter cone . The 2 sets linear motion shaker fit on a 20ft container frame for easy moving . The bottom tank is a 20ft container size mud tank to hold mud from shakers and desander / desilter cones with 3 compartment .

The second mud tank is a 20ft container size mud tank , there are 2 sets decanter centrifuge installed on top which sit on another 20ft container size frame for easy moving . The mud tank is designed to hold mud from 2 sets decanter centrifuge after treated. The middle speed decanter centrifuge will separate solids from 5 to 7 microns after desilter separation which made a great progress on separation for Trenchless mud system .

This 1000 GPM mud system is a very top configuration to contain 2 sets decanter centrifuge . The drilling mud will get heavier and heavier while drilling again and again by recycling cause fine solids will be more and more without a centrifuge , then there will be problem for driller , the 2 sets decanter centrifuge will make it easier while drilling cause they will separate the fines and keep drilling mud in a certain density .

One set drilling cuttings process system can contain auger for delivery drilling cuttings , vertical cuttings dryer or Hi G dryer for drilling drilling cuttings , decanter centrifuge to recyclings fluids after vertical cuttings dryer or Hi G dryer , holding tank to keep drilling fluids recycled from dryer , screw pump for feeding decanter centrifuge .

Economy Option For Drilling Cuttings Process System
