GN Dewatering Unit with Flocculation System
As the fast development of GN Solids Control, GN has provided many sets of solids control systems to clients from various industries. Recently, GN got many inquiries on waste water management, some clients need to separate the clean water from drilling mud can d reused the water.
Although different projects are customized by different working situations, the working principle is pretty the same. Just take one of the dewatering unit that GN Solids Control provide several months before as an example.
This GN Dewatering Unit is composed by the following equipments:
1. GN Double Deck Shale Shaker
It’s used to separate solids that larger than 100 microns. Here we use GNZS706E-HB.
2. GN Desander
Desander is one type of shale shaker with large cylones, which can be used to separate solids larger than 50 microns. Sometimes, GN recommend to use desilter which is equipped with small cylones and can do much finer separation.
3. GN Flocculation Unit
The flocculation is used to add polymers into drilling fluids which can help to collect small diameter solids.
4. GN Decanter Centrifuge
The drilling fluids come from flocculation tank can be further separated by GN decanter centrifuge, which can separate the solids larger than 2 microns.
So after all the treatment by the above solids control equipments, clean water can be separated from drilling fluids or waste water and this clean water can be reused. For some strict demands, such as the discharged mud need to be pretty dry, GN Solids Control recommend to use vertical cuttings dryer.
By using GN vertical cuttings dryer, clients can deal with oil base mud (OBM), water base mud (WBM) and synthetic water based mud (SBM). GN has provided many sets of cutting dryer for mud separation. Based on the working performance, the oil can be separated to below 5% and the water can be separate to below 10%. For details, welcome to contact thomas@gnsolidcontrol.com.
