Due to being made of PVC, it has excellent corrosion resistance, chemical resistance, and water resistance.
In a trough-shaped waterway, the supernatant water from the sedimentation tank overflows through a V-notch. It is lightweight and can be easily and quickly constructed.
Overflow weir (overflow trough) made of PVC
It is a weir for evenly discharging the supernatant water that has been separated by sedimentation in sedimentation tanks (sedimentation chambers) and the like. It is also referred to as an overflow trough. In many cases, a continuous triangular notch (V-notch) is used at the top of the weir. Everything from dimensions, channel width, to outlet size can be manufactured according to your preferences. It is also possible to manufacture only V-notch plates and movable weirs. Brackets and supports can also be provided.

This is a case study of the replacement work of an aging iron overflow weir with a new resin one.
We would like to introduce a case of replacing an aging iron overflow weir in a certain housing complex with a new resin one. The existing overflow weir at the site was at risk of falling due to deterioration, necessitating prompt restoration. After a site survey, we manufactured an overflow weir of the same size using PVC and carried out replacement work, including surrounding equipment. 【Construction Case】 ■ Manufacturing Days: 14 days ■ Type of Work: Equipment Installation ■ Work Days: 2 days ■ Date/Location: June 2019/Shiga Prefecture ■ Equipment Used: Trench, Center Well *For more details, please refer to the PDF document or feel free to contact us.
Since it is made of FRP (fiberglass reinforced plastic), it has excellent corrosion resistance, chemical resistance, and solvent resistance.
In a channel shaped like a trough, the supernatant water from the sedimentation tank overflows through a V-notch. It has a high tensile elongation rate and is resistant to impact.
