vol.1 REINFORCEMENT OF A CONTAINMENT WALL
 

REINFORCEMENT OF A CONTAINMENT WALL

The NIHON KASETSU NWC-60 model used to treat the wastewater from the containment wall reinforcement works.
In this project, a pile driving machine drilled holes along a 30 metre slope and reinforced it with rebar and concrete. The water was used to cool the drill, and was flowing at certain points along the slope. A total of 500 tons of wastewater was purified in this project.
The wastewater generated went through 3 stages before entering the equipment. The first phase was a collection tank for the water, before passing through a pipe to a second tank. It was then stored in a tank at a level above the NWC-60 equipment.
After being treated, the clean water was run off into a nearby river and the sludge stored in another tank for subsequent transport to a landfill site.

Wastewater treatment process
The level of the turbidity was 3000 NTU, giving a treatment capacity of 10m3/h.
