KOSUN DC Series Decanter Centrifuges are used in Drilling Waste Mnagement System

KOSUN  oilfield drilling mud decanter centrifuge can meet with different requirements of mud treatment under various drilling condition, that can do sedimentation and separation for particles more than 2 um. After treatment, the mud can achieve ideal viscosity and proportion, results in better recycling, high efficiency, saving and environment protection.

Decanter centrifuges are used in industrial applications for the continuous separation of solids from liquids where the volume of solids is relatively high. The largest application in the UK is for dewatering sewage sludge containing around 1.5% to 3% solids in water. So the job of the centrifuge is to concentrate the amount of solids to just over 20% and remaining water, known as the Centrate, is as free from solid particles as possible. For some sludges a polymer (a chemical) is added to the process to encourage the solids to settle out of solution which aids the dewatering process.

The mud separation process between solid phase and liquid phase is completed in the roller. Decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of  drilling centrifuge force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

The series of  solid control-centrifuge by our company has been developed many years with the continuous improvement and optimization design, which possesses the characteristics of good result of separation and settlement, as well as large quantity, reliable work, longer life, lower energy consumption, easy maintenance, smooth operation, lower noises, etc.
