Membrane Systems


The integration of submerged membranes within a biological treatment process provides direct filtration of high-level mixed liquor suspended solids (MLSS). Sequential aeration within the biological process promotes biological nutrient removal

By combining membranes with biological reactors results in a unique, time managed treatment system capable of enhanced biological nutrient removal.


Advantages of Biological Nutrient Removal Using Membrane Systems

  • Enhanced biological nutrient removal (EBNR)
    • Total nitrogen < 3 mg/l
    • Total phosphorus < 0.1 mg/l
  • Elevated mixed liquor suspended solids for volume reduction of sludge stabilization
  • Integrated process control
  • Ideal for space restricted applications
  • Rapid solution for augmenting plant capacity
  • Time managed control offers unlimited operational flexibility with fewer tanks

Oldest town in West Virginia adopts modern Aqua-Aerobic® MBR System to meet Chesapeake Bay Initiatives

Read Success Story

In 2010, Shepherdstown selected the Aqua-Aerobic® MBR Membrane Bioreactor as the new system which would treat the town’s wastewater. The decision was based on the ability to utilize the plant’s existing infrastructure without the need for additional tanks.
