Our Strength

Low in running cost

Running cost can be largely reduced compared with conventional method.
Conventional method Method JTOP method
Necessary to take-in/out AC Effort Full automatic Regeneration
A microbe propagates in column Hygienic Sterilizing by regeneration heating
AC is not reused⇒Disposal Waste AC is reused.
  1. Cost of buying new AC
    (Approx.US$2000 /1 m3)
    Price of new AC
    (Approx.US$ 4.5 /1 kg)
  2. Waste disposal costs (Approx.US$300~400/1m³)
  3. Manpower costs of removing AC
Total Approx.US$2500/m³
Running Cost
  1. Electric bill or gas fee during regeneration
    Cost for regeneration of AC (Below US$ 1 /1 kg)
Total Approx.US$25/m³


Estimate for regeneration cost per 1m³ of water treatment

Cost for wastewater treatment of 100 m³with 1m³ of activated.
(The amount of throughput varies depending on the amount of wastewater and the quality of the water)

Size of AC Column
Large AC1m³ (500kg)
約18kW 4h×2 $19/day
約3.7kW 10h $5/day
Control panel
約1kW 24h $3/day
Per 1m³

Note: Estimated electric bill as $0.13/kWh. In the absence of steam supply, costs related to steam supply occur separately.

Space saving design

Compact designed equipment.
Incidental equipment such as stirring or settling tank are unnecessary.

  • Installed in 2013

Footprint ca. 12m³
throughput 50 t/day

Simple to set-up and operate

No engineering work required when installing, because it’s unit type.
Operation with automatic control. Easy operation with touch panel setting.

The activated carbon column can be easily increased as the amount of wastewater is increased.

Wide application for various kinds of water and gases

Specific activated carbon can adsorb various materials of different sizes and properties.

Activated carbon is regenerated and reusable. It reduces a huge energy consumed during incineration.
Reusing treated water to promote zero-emissions at the factory.
