Autonomous and compact plant for biological treatment with membranes.

Compact and autonomous MBR system, which can both integrate hollow fibre submerged membranes as well as flat membranes.

Graphical representation of the MBR biological treatment plant, self-contained and compact, designed and manufactured by SIGMADAF Clarifiers.

Why an advanced membrane reactor?

MBR technology in the wastewater treatment process is a technology that combines the biological degradation process, known as "activated sludge", with solid-liquid separation by membrane filtration.

The decision to select a membrane bioreactor process, or MBR system to the detriment of other conventional systems for treating wastewater is based on the advantages it presents:

  • System effluent quality
  • Compact plant
  • Simple treatment
  • Constant quality
  • Resistance to oxidizing agents
  • Ease of operation

Process management is simple and inexpensive. No sedimentation occurs in the biological tank.

The operator only has to control the operation of the permeate and recirculation pump and the working pressures.

The working parameters are controlled by a PLC that has the possibility of making remote connections via MODEM.

  • Stability and flexibility
  • Modularity
  • Standardization

Thanks to MBR processes and technology, very high-quality effluent is obtained, making it possible to reuse the water in other industrial production processes.


The system can be installed in ISO containers facilitating transport, assembly and, eventually, subsequent extensions.

  • Quick plug&play installation
  • Low space requirement
  • Does not emit odours or attract carriers such as insects
  • High loading volumes
  • Disinfection without UV and chemicals
  • Effluent suitable for agricultural use or as grey water
  • Fully automated process
  • Modular expansion possible
