Our Achievements

Water Treatment Plants

We supply systems that deliver reliable performance and excellent energy savings.
In the area of sludge treatment, our step grate stoker type sewage sludge incineration and power generation system helps reduce greenhouse gases by sewage sludge as a source of energy.

Water Treatment and Advanced Treatment

Upflow moving-bed sand filtration system
"Uniflow Sand Filter"

This sand filtration system can deliver high-speed filtration at up to 1,000 m/day.
Thanks to continuous washing of the filter material, the filtration exhibits stable performance and is adequate both for advanced treatment of discharged water and for generating fresh water from recycled water.

Water Treatment and Advanced Treatment
Denitrification sand filtration and dephosphorization sand filtration

Denitrification sand filtration and dephosphorization sand filtration

Denitrification type

Nitrate nitrogen is removed by denitrifying bacteria that have adhered to the filter sand. Suspended solids (SS) are removed at the same time as nitrogen.

Dephosphorization type

A continuous-washing design yields more stable dephosphorization processing based on coagulation filtration with an added coagulant.
Low-power vertical agitator "Bio Blade Mix"

Low-power vertical agitator "Bio Blade Mix"

This low-power vertical agitator is ideal for use in mixing reaction tanks. With an agitation power density of 1.0 W/m3 to 3.0 W/m3, the system delivers more than adequate agitation power.
Fixed-bed anammox process

Fixed-bed anammox process

This nitrogen removal technology uses anammox bacteria. It offers significant advantages in terms of energy, space, and cost savings compared to conventional systems.
This TAKUMA technology was adopted for inclusion in the FY2012 B-DASH Project conducted by the Ministry of Land, Infrastructure, Transport and Tourism (Japan).

Sludge Treatment

Step Grate Stoker type sewage sludge incineration and power generation system

By taking advantage of the characteristics of step grate sludge incinerators, which require no auxiliary fuel and consume little power, and by optimizing the heat recovery system, we’re able to propose power generation systems that use waste heat from the incineration process in an array of sizes. This TAKUMA technology was adopted for inclusion in the FY2012 B-DASH Project conducted by the Ministry of Land, Infrastructure, Transport and Tourism (Japan).

Sludge Treatment
Rotating drum-type concentrator

Rotating drum-type concentrator

This simple system concentrates sludge using a drum-shaped screen. It uses significantly less power and offers space and cost savings compared to conventional concentrators.
Circulating fluidized bed sludge incinerator

Circulating fluidized bed sludge incinerator

Circulating fluidized bed sludge incinerators efficiently mix and incinerate sludge with a wide range of characteristics. High superficial velocity allows the incinerator to be about half the diameter of a bubbling fluidized bed incinerator.
