Project Achievement

Technical Expertise
Highly Efficient Pressurized Dehydration System for
Recyclable Bottom Sediment (PFP: Power Filter PressSystem)

The dredged-soil high pressure dewatering treatment system is aconstruction method which mechanically dewaters dredged soil
under a filtration pressure as high as 4 MPa, realizing extensive
volume reduction and effective utilization of the soil.

Tornado mixing
Pipe-mixing solidification treatment method

A Large-sized pneumatic mud transportation vessel"Fujin Maru"

The vessel is suitable for discharging dredged soil, lifting mud,and/or applying the in-pipe-mixing solidification treatment
method, in coastal constructions.

SS caisson method
The method which is gently and accurately install thecaisson in non-loading"Tornado Mixing Method ” , being one of the pipe-mixing
solidification methods, produces and delivers solidificationtreated soil with desired strength by adding a solidification
agent to soft soil during the process of its pneumatictransportation and by mixing them with use of the plug flow.
"Tornado Mixing Method" is remarkable in that it does not choose
type of pneumatic transportation systems, enabling application
to either seaborne reclamation works or shore-based reclamationworks.

ID Circulating-flow purification system
Microorganism circulating-flow purification method"ID Circulating-flow purification method" purifies water of closed areas such as park ponds or appreciation ponds by removing suspended
solids (SS) and inhibiting growth of phytoplankton. The system, which has a very small "circulation-flow generator" set up underwater,
accelerates decomposition of organisms by spreading suspended-solids precipitation agents and purification microorganisms with the waterflow throughout the water to be purified, and realizes the water purification in a short period.
