– The 50th Ceremony of the Excellence in Environmental Equipment Awards – “Chairman’s Award of the Japanese Society of Industrial Machinery Manufacturers”

  • High cost of consumable part replacement
  • Decline in dewatering performance over time due to wear and tear
  • Difficulty handling sludge that clogs easily, such as fibrous or inorganic sludge

By evolving from the traditional “one screw per cylinder” design to a “two screws per cylinder” structure, VOLUTE DUO™ offers the following advantages:

  • Significant reduction in consumable parts cost
    By eliminating the physical contact of consumable parts, we have realized approximately 52% in cost savings compared to its predecessor.
  • Sustained dewatering performance over time
    Minimizing wear-induced degradation ensures long-term stable operation.
  • Compatibility with a wide range of sludge types
    Enables stable operation even with clog-prone sludge containing high levels of fibers or inorganic materials.

Thanks to this technological innovation, VOLUTE DUO™ has achieved 20 installations worldwide since its launch in 2021. We are currently receiving over 10 inquiries per month, with nine units scheduled for delivery between late March and September 2025. This momentum suggests that the VOLUTE DUO™ will see further expansion both domestically and internationally, with potential for adoption in new industries and facilities.

Sludge accounts for approximately 40% of industrial waste and is often incinerated or landfilled. The proper treatment in reducing the volume of sludge will be a critical challenge in achieving environmental conservation, CO₂ reduction, and a sustainable society.

Inspired by this award, our company will continue to pursue technological innovation in sludge treatment and remain committed to developing and promoting more efficient and environmentally friendly sludge dewatering solutions.
