ZeeLung
An innovative & sustainable solution to increase treatment capacity and improve effluent quality
Upgrading wastewater treatment plants for capacity expansion or nutrient removal is challenged by process complexity, the need for larger tank volumes and increased energy consumption.
ZeeLung is an innovative solution that maximizes the treatment capacity from existing tank volumes while also reducing energy consumption. Conventional solutions require the construction of new tanks and other process intensification technologies are complex and energy-inefficient. ZeeLung, on the other hand, is a simple solution that increases treatment capacity in existing assets and reduces energy.
Resilient, simple & sustainable wastewater process intensification
ZeeLung Overview
ZeeLung maximizes treatment capacity in existing tank volumes while also reducing energy consumption.
During secondary treatment, bacteria metabolize nutrients and organics – and need a flow of oxygen to get it done. Oxygen is typically pumped through diffusers to create bubbles. But most of the oxygen rises to the surface without being used and valuable energy is wasted. At SUEZ, we saw a new approach. While conventional solutions require the construction of new tanks, ZeeLung increases treatment capacity in existing assets and reduces energy use. ZeeLung enables process intensification and process resilience. The result is expanded treatment capacity, stabilized cold-temperature performance and rapid response to load changes.
ZeeLung solves the following treatment challenges:
- Increase treatment capacity
- Augment ammonia removal
- Implement nitrogen removal
- Enable biological phosphorous removal
ZeeLung Benefits
- Process intensification – Up to 50% more treatment capacity and/or performance in existing tank volumes.
- Process resilience – The attached growth biofilm is resilient to load variations and upset conditions.
- Simple solution – ZeeLung cassettes are installed into existing bioreactor tanks, avoiding the need to build new tanks and allowing fast implementation.
- Energy savings – Oxygen transfer is up to 4X more efficient than fine bubble aeration, resulting in up to 50% energy savings.
