Green Shell
It is great at removing both the sedimentary and suspended contaminants, excluding the still water, and backwashing the
screen. It can be used as a pre-treatment facility for a detention pond, and installation is cheap in light of the
processing amount.
It is a technology of treating various types of non-point source contaminants through coarse and fine screens.
Name of Construction Method
Green Shell
Outline
Overview of Construction Method
①
Inflow → pre-treatment (coarse screen) → main treatment (fine screen) → discharge
②
Principle :
- Technology of treating various types of non-point source contaminants through coarse and fine screens.
- Inflow (pre-treatment area): coarse screen (removes impurities 8mm or larger)
- Main treatment : fine screen (removes impurities 3mm or larger)
③
Maintenance :
- After heavy rain, dredge the impurities inside the screen and the lower sedimentation sludge and discharge the still water
- Regular maintenance (2 years)
Excellence of Technology
Simultaneous removal of sedimentary and suspended contaminants
Disposal of still water and backwashing of screen
Can be applied as a detention pond’s pre-treatment facility
