Screw Decanter Centrifuge


  • HS-L type

    HS-L type

    General purpose type
    Of all the Screw Decanter Centrifuges, the HS-L type is the best for general purpose and is widely used in various fields.
  • HS-DP type

    HS-DP type

    Deep pool type for dehydration of organic sludge
    Energy Saving with Deep Pool shape rotator. The back drive system is standard equipment.
  • HS-LS type

    HS-LS type

    Sanitary type
    Sanitary type equipped with Automatic Washing Device for various uses such as Food, Medicines, and Fine Chemicals.
  • IX-T type

    IX-T type

    Energy saving, low noise, less space
    Developed under the concept of "Gentle to the Earth". Light weight, small installation space and low noise type decanter. It can give its best performance in the field of sewage disposal.
  • ISC-H type

    ISC-H type

    Energy saving thickener
    Compared to the former methods, its energy saving efficiency is much greater including both power consumption and Motor Output.
  • MW type

Principle of IHI Screw Decanter Centrifuge

  • To separate the mixture fluid between solid matter and liquid, setting ponds, which use the specific difference in gravity, have long been applied. Applying this device, if you supply mixture fluid from pipe A, solid matter settles down and separates into bowl B, which results in outflow of supernatant fluid from weir C. STEP2 STEP3 STEP4
