This is the last working week before Chinese Lunar New Year holiday, after that offices and workshops will be closed for a 2-week holiday. All GN workers are working day and night in order to ship as more as orders before the 2-week holiday.
Some dewatering centrifuge units are dispatched to sea port, they will be exported to a Southeast Asia client. The dewatering centrifuge units will be used for TBM mud treatment. TBM is short for Tunnel Boring Machine, it has a wide application in railway, hydropower, transportation, mining, municipal and other tunnel projects. 
Drilling mud is used to lubricate drilling bits during Tunnel and Boring drilling activities. For environment protection, the drilling mud and waste water must be recycled and reused during and after the drilling activities. Besides normal mud desanding plant, dewatering centrifuge unit is also requested in some application to treat the waste water.
GN dewatering centrifuge unit consists of big bowl big ratio decanter centrifuge, and chemical dosing unit. The decanter centrifuge and chemical dosing system is combined as a full package unit to remove as more ultrafine solids as it can do. The decanter centrifuge and chemical dosing system are both allocated inside a fabricated container. The full package can be shipped as a shipper owner container during international shipment. And the containerized design can protect the centrifuge and chemical dosing system, which values much. And they are easy for shipment between different jobsites.
Decanter centrifuge itself is a Physical separation machine. It can only separate solids by particle sizes. It cannot remove ultrafine solids smaller than the cut point. By chemical dosing, the ultrafine solids can be flocculated, and reach the centrifuge cut point for solids removal.
Besides dewater centrifuge unit, GN Solids Control makes full line desanding separation equipment for TBM and other trenchless no dig activities, like shale shaker, desander, desilter, etc…
