活性污泥厂通常存在两个限制处理能力的工艺瓶颈：

生物反应槽的性能受槽容积和系统中细菌存量的限制，因而限制了该工艺所能达到的最高营养物去除量。

二级澄清池的性能受澄清池表面积和混合液沉淀特性的限制。

ZeeLung MABR with zeeDENSE breaks through both bottlenecks by combining two proven intensification technologies – ZeeLung MABR & densification.

优势包括：

提高生物反应器和二级净化器的处理能力
改善沉淀
加强营养物去除，包括生物除磷
温室气体减排
等等

市政废水处理应用：

占地面积受限而产能需求增加的工厂
需要改善营养物去除的工厂

工作原理

ZeeLung MABR with zeeDENSE couples the synergies of ZeeLung MABR with continuous flow densification.

ZeeLung MABR加强了现有生物反应槽的营养物去除。浸泡于混合液中的ZeeLung盒可支持生物膜的生长，增加系统中营养物去除细菌的数量。ZeeLung介质可通过“呼吸”（在不使用气泡的情况下将氧气转移到生物膜中）降低能源消耗，并减少N2O排放。ZeeLung可以提供高达50%的容量扩展，同时减少高达75%的曝气能量，并减少温室气体排放。

致密化加强了二次澄清。水力旋流技术利用重力选择压力来保留密集的生物质，并有选择地废弃密度较小的生物质，包括丝状细菌。废弃的活性污泥或混合液通过zeeDENSE系统进行处理，致密的生物质被送回生物反应槽，而密度较低的生物质则从该过程中废弃掉。其结果是改善了混合液的沉淀特性，从而使二次澄清的强化程度达到50%。

ZeeLung MABR with zeeDENSE is tailor-made for the upgrade of activated sludge plants with modularity, process flexibility and speed of implementation. The combination of densification and ZeeLung MABR creates a wastewater technology more efficient than ever without having to increase your plant footprint.

案例研究

ZeeLung MABR with zeeDENSE Intensify Wastewater Treatment at the Yorkville-Bristol Sanitary District: 下载完整案例分析

The Yorkville-Bristol Sanitary District faced multiple challenges including capacity constraints from population growth and industrial loads, space limitations, and phosphorus discharge compliance requirements. In 2017, they implemented ZeeLung MABR technology as a solution. When increased flow created new clarifier capacity challenges, the facility was further upgraded in 2023 with ZeeLung MABR with zeeDENSE technology providing a 40% increase in secondary clarifier capacity without new construction and 75% chemical savings from optimized biological phosphorus removal.
