0183 Spring-loaded Weir UFT-FluidFlap
Intended Purpose
The Spring-loaded Weir UFT-FluidFlap is a self-regulating discharge device for use as an overflow weir at combined sewer overflow tanks and in other storage structures. Compared to a fixed weir, the flap has a much lower apparent overflow head for the same discharge and the same length and keeps the water level almost constant after the discharge has started.
Properties of the Spring-loaded Weir UFT-FluidFlap
- considerably greater discharge capacity than with a fixed overflow sill
- the rise in the water level from the beginning of the overflow to large discharges is limited to a few centimeters
- activation of additional storage volume, at the same time avoiding an excessively high water level in the inlet sewer
- significant reduction in the length of the overflow weir and thus also in the size and costs of the structure
- reduced discharge of pollutant particles transported near the sewer bottom (bed load) because the water is passing over the weir rather than underneath
- automatic operation without external energy
- flex free and torsionally rigid construction made of stainless steel
- resetting mechanism in the form of space-saving arranged compression springs
- no cables, counterweights or cam discs
- high operational reliability
- long lifetime, low wear tendency
