PDF (Polyethylene Double Frame) panel made of HDPE(High-Density Polyethylene) do not have corrosion and have insulation property like the double frame panels with lasting material properties. The panel is highly adaptable to temperature change (-40C ~ 100C) and is safe from producing harmful substances due to material corrosion. The panel is a very economical technical alternative product due to its easy assemble on site and a short construction period.
Inflow of raw water, baffle wall, Cohesive point GRP(Paddle), Cohesive point(Baffle wall), Sedimentation site (baffle wall), Sedimentation site(partition), Water supply, Baffle wall PDF wall panels overcome the shortcomings of conventional concrete walls with low processing efficiency, inefficient structure and complicated construction, and durability problems due to corrosion, deformation and non-economic problems. PDF wall panels provide appropriate construction measures for old and new water and sewage treatment facilities to improve and enhance efficiencies.
A clean and sturdy baffle wall using PDF (Polyethylene Double Frame) panel made from HDPE (High-Density Polyethylene) raw materials. To increase the contact time among the proper disinfection (CT) of the clean water reservoir, the baffle walls are installed to shorten the construction time and do not produce any harmful substances to the environment.
Vertical Baffle
When installing the baffle work, plate and bolt are used instead of anchors. The method shows a new concept of installing baffle walls and preventing the damages to the structures and waterproofing layers.
By identifying the flow characteristics of the Pilot Plant experiment of the water treatment with PDF Panel and the flow when flowing through rectifying, sediment removal efficiency can be reviewed by comparing various rectifying and opening rate changes. The baffle wall method is an excellent new concept that has great baffle effects, harmless to human, excellent constructibility and economic efficiency, and great advantages in environmental aspects.
The distance after the rectifying wall | Sedimentation amount of Sludge(cm) | ||
Circular rectifying (Type A) | Upward and downward contracted rectifying (Type B) |
Downward-contracted rectifying (Type C) |

120 | 5.2 | 4.8 | 6.5 |
ㆍThe top of the Circular baffle and U/D contracted baffle maintained higher turbidity than low
ㆍDonward-contracted baffle showed a great turbidity removal rate for good baffle effect
A method using PDF Panel to install unit division barrier for performance improvement construction (advanced processing facility) in sewage processing plant (waste water processing). The construction method saves great amount of construction period compared to conventional concrete construction methods and has no corrosion factors which immensely improves durability.
Removes density current from settling tank to inhibit the rise in float. Great construction method especially for case of great flow change, turbidity 38%, high-turbidity 22%(sedimentation turbidity)
