Inclined Plate Clarier and Decanter Centrifuge for Overseas Client

Recently, GN has completed the assembly of one set of tank flushing mud water separation system, which will soon be sent to the domestic customer's site. In some drilling sites or construction sites, tanks are often used to store the mud used in the construction process. After the mud is used, high-pressure water is usually used to flush the tank interior, so as to discharge the sediment accumulated at the tank bottom. How to recycle and reuse this flushing water is a problem that can be solved by GN tank flushing mud water separation system.

GN tank flushing mud water separation system is a solid-liquid two-phase separation solution, which aims to separate the solid particles in the tank cleaning water, so that the recovered water can be recycled and the operation cost can be reduced.

The mud water separation system is mainly composed of four modules, namely, feed module, flocculation module, sedimentation separation module and circulating water discharge module.

1. The feeding module is composed of a hose pump and a prefilter, which is used to transport the mud water to be treated from the storage area to the mud water separation system.

2. The mud water separation mainly occurs in the clarifier separation module. The main equipment in this module is an inclined plate clarifier. After the muddy water enters the machine, the solid phase in the mud water will be intercepted by a group of inclined plates installed in the machine during the process of moving toward the exit, and then it will settle into the V-shaped groove at the bottom of the machine under the action of gravity, and then discharged out of the system through the screw at the bottom and the diaphragm pump at the slag discharge port.

3. The flocculation module is a chemical dosing unit consists of PVC reagent barrel, mixing device and dosing pump, which is mainly used to prepare flocculant and then deliver it to the inclined plateclarifier. By adding flocculants, the fine particles in the muddy water can form flocs, thus improving the separation effect.

4. The clarified water discharged from the overflow port on the upper part of the clarifier enters into the storage tank, and then is discharged by the high-pressure water pump or transported to the high-pressure jetting machine for recycling.

In this project, the customer also ordered the sludge dewatering centrifuge module. The sludge discharged from the slag discharge port of the inclined plate clarifier still has more water, which is not conducive for transferring of sludge. After the settled sludge is sent to the dewatering centrifuge for further treatment, a relatively dry and stackable sludge cake can be obtained, which provides convenience for further drying treatment and transportation.

The mud water separation system and sludge dewatering centrifuge package are of modular design, compact structure, convenient for overall transportation and site layout. For more information about mud water separation equipment, please contact GN Separation.
