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 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 Veolia, 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.
