Nikkan Tokushu has been doing business in the environmental industry in Japan for over 30 years. We are engaged in the treatment of household and industrial wastes and the design, installation, and management of circulation systems. Nowadays we are also involved in the collection and transportation of wastes, taking care of wastes from discharge to treatment. Our other projects include the design, installation, and management of sewage treatment facilities, night soil treatment plants, waste incineration plants, and other systems. We will actively provide Nikkan Tokushu technologies for overseas markets. Please feel free to contact us with any inquiries.

Can be installed on an existing sludge disposal line.

Reduces sludge volume by half, and doubles biomass energy.
The UMEDA PROCESSOR (high-speed rotating disk) crushes cell membranes of microorganisms in sludge and extracts proteins, carbohydrates, fats, CO2, and H2O to improve dehydration efficiency. This helps reduce the amount of solid materials to be transferred.
Use of the equipment can improve the digestion efficiency of a digester tank from the conventional rate of 40% to 60–80%. This enables an increased amount of digestion gas generated in the digester tank, thereby allowing a highly efficient supply of energy. The equipment is used in food manufacturing facilities. Furthermore, it can withstand continuous operation by crushing a large amount of microalgae. The UMEDA PROCESSOR is characterized by its low technology use, low cost, and high quality.

Merits of introducing the UMEDA PROCESSOR

Comparison of digestion efficiencies of the digester tank in the facility
  • Existing facility
    40 %
  • After introducing the UMEDA PROCESSOR
    Largest 80 %

Compared with the rates for the existing facility before the UMEDA PROCESSOR was introduced, the equipment can improve dehydration efficiency, reduce water content and the quantity of solid cakes to be transferred, and increase the digestion efficiency of the digester tank from the conventional rate of 40% to 60–80%.

  • MERIT 1 Increases water
    content in the
    dehydration process.
  • MERIT 2 Reduces transferred
    sludge by half.
  • MERIT 3 Shortens the digestion
    reaction period by half.
  • MERIT 4 Can be installed
    on an existing
    sludge disposal line.
  • MERIT 5 Minimizes the sludge
