Bolina Permanent Debris Booms

Permanent Debris Booms

Permanent installation for containment and recovery of floating debris.

Bolina Permanent Debris Booms (PDB range) - the original floating debris barriers with a fully flush face for automatic debris deflection - can be installed permanently to contain and recover floating debris, such as barrels, logs, trees, reeds, duckweed etc. into a collection area, where the material can be easily extracted for recycling.

Workboats can rub along the face of the debris booms, scooping up materials. This avoids having to slowly 'nibble' at the debris and risk damaging the floats as with conventional debris booms.

The booms are usually supplied with a roller compensator to match varying water levels.

The Bolina Permanent Debris Booms first installed in 2001 are still in service. Most recently, we engineered the longest river barrier that was installed in Europe.

Product:Permanent Debris Booms (PDB)
Models:PDB400 / PDB600
Applications:They are used to control the flow of debris and pollution and are frequently used to protect critical infrastructure.

  • The flush face design makes the boom self-clearing when installed at a suitable angle to the current flow, allowing for easily debris collection at a convenient point or deflecting debris away from sluices or intakes to stop them from getting blocked.
  • The flush front to the curtain, which is highly resistant to abrasion, chafe and impact damage, avoids debris getting “hung up”. The buoyancy floats are attached behind the curtain on the downstream side providing maximum protection from any possible damage.
  • The booms are simple to construct and are provided in lengths to meet exact client requirements.
