Simple & Sustainable ' • Intensification of Activated Sludge WATER TECHNOLOGIES

Get more from your activated sludge assets The Zeelung Membrane-Aerated Biofilm Reactor (MABR) is a gamechanging technology used to upgrade conventional activated sludge plants and avoid the construction of new bioreactor tanks. ZeeLung MABR expands plant capacity and improves nutrient removal in a simple, fast and modular way while also reducing energy and mitigating GHG emissions. ZeeLung MABR is a simple and sustainable solution that offers: • Process Intensification: Up to 50% more treatment capacity in existing tanks • Simplicity: Installed in existing tanks, no civil works, fast implementation...

Experience Upgrading wastewater treatment plants for capacity expansion or nutrient removal can be complex and expensive because of the need for new tank volumes and increased energy consumption. Unlike conventional solutions, ZeeLung enables utilities to get more out of their existing wastewater treatment assets with a simple solution that also saves energy.

Case Studies Increased Wastewater Treatment Capacity at Yorkville-Bristol Sanitary District Population growth, the arrival of new industrial contributions and a new phosphorous removal permit required the Yorkville-Bristol Sanitary District in Yorkville, Illinois, USA to be upgraded. The existing site was footprint constrained and the end-user sought a retrofit solution that would minimize capital expenditure and avoid significant civil modifications. Yorkville chose a ZeeLung MABR upgrade because it could increase the organic treatment capacity of the plant by 45% in the existing tanks while...

zeeDENSE*: Super-Intensification of Activated Sludge zeeDENSE is an application of ZeeLung that couples MABR & inDENSE continous flow densification technology for super-intensification of activated sludge plants. ZeeLung MABR intensifies biological capacity by up to 50% and inDENSE adds a further up to 50% intensification of secondary clarification. Waste-activated sludge or mixed liquor is processed through the inDENSE system and the dense biomass is returned to the bioreactor while the less dense biomass is wasted from the process. zeeDENSE is tailor-made for the upgrade of activated sludge...
