Decanter centrifuge is widely used to separate (dewater) solid materials from liquids in solids control system when they are mixed together in mud. Meanwhile decanter centrifuge is also applied in many industries such as:
1. Solids separation (oil well drilling, refining, de-watering)
Sludge dewatering is the separation of a liquid and solid phase whereby, generally, the least possible residual moisture is required in the solid phase and the lowest possible solid particle residues are required in the separated liquid phase ("the centrate").
2. Industrial and biological wastewater treatment
Industrial wastewater treatment plants are designed to meet pretreatment water requirements prior to downstream municipal facilities and / or produce clean, safe water for direct discharge within the required limits. As the requirements for cleaner discharge waters increase so does the sophistication of industrial treatment processes being designed and built today. And, decanter centrifuges are being extensively used more and more for liquid- solid separation, sludge dewatering, and sludge thickening applications as part of these pretreatment and / or full treatment operations.
3.Sludge Thickening
The thickening of activated sludge is a common practice many wastewater treatment plants. These plants use a biological treatment process to reduce the wastewater COD and BOD before discharging downstream into the environment. During the process colonies of bacteria develop and grow forming a biological body which produces a solid waste as it feeds on the chemicals and nutrients.
4. Food processing (olive oil, wine, fruit juice)
5. Fish processing (fish meal, fish oil)
