Decanter Centrifuge

Product InformationDecanter Centrifuge

3 Phase Separation for Industrial Fluids
  • Best Efficiency-Guaranteed 3 Phase Centrifuge
  • Oil and Water Separating Decanter Most Selected by Clients

Technology Summary

  • In regards to traditional oil and water separation of processing wastewater, only the separation of solids and liquids or separation of two liquids with different densities were achieved, but SENTEC Technology’s 3 phase centrifuge can be applied as a suitable solution for wastewater line discharged as a mixture of various materials(3-phases).
  • This product can handle the consecutive separation of three phases (solids, heavy liquid, light liquid) in a single process, and it is used as an attractive method for processing oily wastewater sludge and fat(oily substance) retrieval process.
  • SENTECH Technology’s 3-Phase centrifuge is the first developed and commercialized 3-phase centrifuge in Korea, and it realizes 3-phase separation with just one continuous process. This design reflected the distinction of solids with specific weight and different densities, securing a high degree of oil substance retrieval rate.

Applicable Area

  • Processing wastewater, a mixture of water, sludge, and oil.
  • Separation of food waste, wastewater, fish oil, fish juice waste, and animal/vegetable oil
  • Oil tank sludge/engine oil/waste lubricant
  • Separation of rolling oil, cutting oil, mineral oils
  • Separation of seed oil including coconut oil, olive oil, peanut oil, etc., and food oil


  • A specially designed separation diaphragm panel and variable impeller provide the following benefits to the 3-phase centrifuge users. As multiple processing stages are combined to neglect the necessity of an additional centrifugation process, users can benefit from a huge cost reduction. Also, it is an efficient product that can easily adapt to varying material conditions, giving it high selectivity and versatility.
  • SENTEC Technology’s 3-phase centrifuge has its quality verified to be best in Korea, it provides services grafted with the company’s experience from the project planning, maintenance/management, spare parts supply, etc.
