MBR / MBBR

High-quality treatment solutions with advanced membrane and biofilm technologies
MBR (Membrane Bioreactor) and MBBR (Moving Bed Biofilm Reactor) technologies are advanced solutions that offer high-quality effluent and compact design in municipal wastewater treatment. As PİLSAN İNŞAAT, we design, construct, and commission these technologies as turnkey solutions in projects with limited space, high quality requirements, and recovery goals.
MBR (Membrane Bioreactor)
In MBR systems, biological treatment is combined with membrane filtration. UF (Ultrafiltration) or MF (Microfiltration) membranes are located inside the activated sludge reactor. This enables physical sludge separation, high-quality effluent, and suitability for recovery. Provides compact design, low space requirement, and effluent quality fully compliant with discharge regulations.
  • High-quality effluent: BOD < 5 mg/L, COD < 30 mg/L, no suspended solids
  • Compact design: 50-70% less space compared to traditional systems
  • Recovery suitability: Can be upgraded to drinking water quality with advanced treatment or reverse osmosis
  • High MLSS concentration: Operation in the range of 8,000-15,000 mg/L
  • Nitrogen and phosphorus removal: Nutrient removal with anoxic/anaerobic zones
MBBR (Moving Bed Biofilm Reactor)
In MBBR systems, high surface area carrier materials (biofilm carriers) are in motion inside the reactor. Biofilm forms on these carriers and organic matter, nitrogen, and phosphorus removal occurs. It is a compact, modular, and high-loading capacity system. Can be easily integrated into existing plants or used as the main process in new plants.
  • High loading capacity: 3-5 times higher than traditional activated sludge systems
  • Compact design: Low space requirement, easy integration into existing plants
  • Flexible operation: High tolerance to load fluctuations, rapid startup
  • Nitrogen removal: Nitrification-denitrification with anoxic zones
  • Low sludge production: High sludge age in biofilm systems, low sludge production
