A3-USA offers the latest wastewater technology combined with the advantages that a small company provides – personalized service, attention to detail, and low cost. They supply plants and equipment that apply membrane technology to water and wastewater treatment processes. They also offer a full range of consulting services for their projects. Services and products include, but are not limited to:

Membrane Bioreactors (MBR) – Plate Ultrafiltration Membranes

Design and supply of complete new MBR wastewater treatment plants using both modular container construction for small municipal and industrial applications, and large scale wastewater treatment plants.

Design and supply of equipment to optimize existing treatment facilities to increase capacity and improve effluent quality.

Membrane Bioreactor (MBR) Plants


  • Operation at higher MLSS concentration resulting in a more robust process
  • Compact footprint
  • Lower waste sludge production
  • Ease of operation and less operator attention
  • Sludge generated from the process requires less dewatering due to the high solid content
  • Disinfection is reduced or eliminated
  • Provides consistent, superior effluent quality
  • Effluent is reusable / recyclable

Applications & Clients
