ZeeWeed* Membrane Bioreactor with zeeDENSE*

释放MBR潜力：通过选择性去除和浓缩来调节混合液

Membrane Bioreactors (MBR) are normally operated with uncontrolled MLSS (Mixed liquor suspended solids) characteristics which limits the full potential of MBR performance. ZeeWeed MBR with zeeDENSE is an innovative technology that combines ZeeWeed MBR with continuous flow densification to optimize membrane and biological performance.

概览

ZeeWeed MBR with zeeDENSE reduces operating cost by tailoring mixed liquor characteristics to optimize membrane & biological performance.

优势包括：

膜性能

  • 减少胶体污垢
  • 减少膜清洗工作
  • 提高污泥过滤性能
  • 提高渗透性
  • 在膜的整个使用寿命期间优化性能

生物性能

  • 提高抗性
  • 生物除磷优化
  • 消除泡沫滋扰

ZeeWeed MBR with zeeDENSE can be used for a range of applications:

  • 市政 - 优化膜和生物营养物去除性能
  • 工业 - 提高生物抗性和膜性能
  • 升级现有MBR工厂 - 对现有MBR工厂进行改造

服务模式

ZeeWeed MBR with zeeDENSE uses a hydrocyclone to separate activated sludge into a dense and light fraction. The dense fraction is returned to the biological process and the light fraction is discharged to solids treatment. The result is selective wasting of bacterial populations that negatively impact MBR performance and retention of densified biomass fractions that improve biological and membrane performance.
