Membrane Bio Reactors (MBR) from MSE Systems combine activated sludge treatment with a membrane liquid-solid separation process.

The system uses low pressure Micro Filtration (MF) or Ultra-Filtration (UF) membranes, eliminating the need for clarification and tertiary filtration.

MBRs are suitable for municipal and industrial wastewater treatment, and can produce high quality effluent from domestic wastewater for discharge to coastal, surface, or brackish waterways, or for urban irrigation.

MBR treatment plants are compact and can be designed for various site situations. The system achieves reductions in Chemical Oxygen Demand (COD) and suspended solids, supporting cost savings for water companies using the mogden formula.

Features and benefits

  • Combines activated sludge treatment with membrane liquid-solid separation

  • Uses low pressure Micro Filtration (MF) or Ultra-Filtration (UF) membranes

  • Eliminates need for clarification and tertiary filtration

  • Produces high quality effluent suitable for discharge or urban irrigation

  • Overcomes limitations of poor sludge settling in Conventional Activated Sludge (CAS) processes

  • Compact design suitable for various site situations

  • Guaranteed reductions in Chemical Oxygen Demand (COD) and suspended solids

  • Supports cost savings on water company bills using the mogden formula

Applications

  • Municipal wastewater treatment

  • Industrial wastewater treatment

  • Domestic wastewater treatment for discharge to waterways or urban irrigation

Performance

Capacities from 4 to 400 m3/hr can be accommodated. Achieves reductions in Chemical Oxygen Demand (COD) and suspended solids.

Materials

Uses Mitsubishi hollow fibre membranes.

Installation

Membranes are typically immersed in the aeration tank; some applications use a separate membrane tank. Compact design allows incorporation into many site situations.
