The Combigreen™ is a low energy product combining a fine bubble annular aeration channel and a central clarifier with an optimized hydraulic profile. It is a compact work, a high length of water for more operational reliability.
The Combigreen™ integrates accessibility and maintenance solutions developed with the operators, including :
- Treated water collection through an immersed drilled pipe or through a conventional nozzle with automatic cleaning
- Travelling bridge spread over the work for an access in all points along the tank
