Our Treatment Technologies

Membrane Bioreactor (MBR)

Combining biological treatment with our patented A3 MaxFlow™ ultrafiltration membranes, MBR systems provide exceptional effluent quality in a compact footprint. Operating since 2000, MaxFlow™ membranes are trusted worldwide for their durability and performance.

  • Compact Footprint
  • High pathogen and solids removal
  • Robust membrane materials for long-lasting performance
High-capacity modular water treatment tanks with durable piping and infrastructure, designed for industrial and municipal water filtration systems.

Our Treatment Technologies

Sequencing Batch Reactor (SBR)

Our SBR systems treat wastewater in timed cycles—combining aeration, settling, and decanting in a single tank. This approach reduces infrastructure and adapts well to fluctuating flow rates.

  • Compact, single-tank design
  • Automated controls with minimal operator input
  • Cost-effective for variable flow conditions
Our Treatment Technologies

Conventional Activated Sludge (CAS)

CAS systems are the backbone of large-scale municipal and industrial wastewater treatment. Simple, proven, and scalable, they’re ideal for facilities needing reliable performance over time.

  • Trusted and widely used technology
  • Simple to operate and maintain
  • Scalable for large treatment volumes
