Road Curtain Wall
It has excellent treatment efficiency as the filter area gets larger toward the center due to the multi-stage filter
media structure. Also, it lessened the possibility of blockage using the density of the multi-stage filter media, and
stage-by-stage processing is possible. It was designed such that in the event of overflow due to an increase in water
flow, drainage will be easy.

① Bridge rainwater inlet→ initial rainwater collection tank → fine screen → Curtain Wall(1st filter medium layer) → Curtain Wall(2nd filter medium layer) → discharge
2
Principle
- - The initial rainwater that is collected in the bridge rainwater inlet flows into the treatment device
- - Forms a radial flow of the moving water from the center to the edge
- -The water passes through the fine screen. In the 1st filter medium layer, the 1st impurity treatment takes place.
- -At the edge, where the velocity of the moving water decreases, the 2nd filter medium layer is installed/the contaminants are treated.

Maintenance :
- An easy maintenance system from which the garbage collecting net part can be separated.
