Wasterwater Treatment Plants

A3-USA designs and manufactures membrane bioreactor (MBR), sequencing batch reactor (SBR), and conventional activated sludge (CAS) wastewater treatment plants. We are the only MBR plant integrator who manufactures the complete plant, including the membrane modules.

  • Membrane Bioreactors (MBR)
  • Sequencing Batch Reactors (SBR)
  • Packaged MBR & SBR Plants
  • Conventional Activated Sludge (CAS) Packaged Plants
  • Containerized Treatment Plants

Wastewater Membranes

We are one of the few treatment plant suppliers that also manufacture membrane modules. This provides us with a dynamic knowledge base that most MBR plant integrators cannot match.

  • Single-stack membrane modules
  • Double-stack membrane modules
  • Triple-stack membrane modules
  • Quad-stack membrane modules
  • Custom membrane multi-modules
