Anaerobic MBR (AnMBR) is ideal for the treatment of high-strength wastewater, achieving maximum conversions of organics into biogas. It deals with FOG, conductivity and solids more robust and efficient than other anaerobic technologies. Ultrafiltration membranes ensure complete solids retention, efficient system operation, and stability of the anaerobic process at all times.
Years of Experiences
Industries worldwide are dealing with challenges in reducing their water and carbon footprint. AnMBR is a leading-edge technology for treating the complex high-loaded wastewaters, producing a superior quality effluent, and transforming the organic pollutants into green energy in form of biogas.
Both the aerobic and anaerobic processes use microorganisms to digest the organic matter. However, the microorganisms involved in each process utilize distinct metabolic pathways. While aerobic process uses oxygen, the anaerobic occurs in an oxygen-free environment and operates with positive net energy production. The organic matter is transformed into CO2 and methane (CH4), producing biogas that can be used as a renewable source of power or heat. The anaerobic process produces less sludge, with the corresponding savings in sludge handling costs.
Feature | Aerobic | Anaerobic |
Energy | Higher, due to aeration | Minimum, positive net energy generation |
Organic load | Low – medium (COD < 10 g/L) | Medium – high (COD > 10 g/L) |
Effluent quality | Very good (COD < 100 mg/L achievable) | Good, higher COD (~ 3-5x) |
Nutrient removal | N and P removed (with the appropriate reactor configuration) | Limited N removal and moderate P removal, depending on technology |
Sludge production | High (30-40% of the inlet COD) | Low (8% of the inlet COD) |
Biokinetics | Simple, generally stable | Control required (pH, T…) |

Industries producing high-load wastewater like dairy, distilleries, slaughterhouses, confectionery, and fish processing benefit from our external AnMBR solutions. These solutions use tubular UF modules with a complete-mix digester, handling high organic loads (OLR up to 8 – 10 kg COD/m³·day). UF membranes ensure biomass retention within the anaerobic digester, enhancing digestion, making it robust, and increasing biogas production. Achieve over 98% COD removals in a single-step AnMBR, avoiding post-treatment and enabling reuse or high-quality water production through reverse osmosis.
AnMBR achieves the highest COD removal, allowing the discharge to the municipal sewer without further treatment in most cases.
Ability to handle high TSS and FOG concentrations, simplifying the pretreatment and maximizing the conversion of organics into biogas.
UF membranes avoid the washout of biomass, resulting in rapid start-ups, specialized microbial communities and robustness against organic or toxic shocks.
Eliminating the DAF pretreatment greatly reduces the chemical consumption and avoids the generation of big amounts of sludge, that require on-site treatment or need to be hauled away.
Made in a state-of-the art LEAN-production facility, with highly-trained production personnel and materials of the highest quality.
With 50 years of experience and more than 2.000 project references across the globe, Berghof Membranes is the leading manufacturer of high quality tubular membranes.
To prevent fouling and clogging, Berghof Membranes developed its line of robust tubular UF (ultrafiltration) membrane modules based on inside-out crossflow filtration.
Berghof Membranes developed B-SMART®, a customizable external membrane filtration system that can be designed with various features and functionalities.
Bridging the gap between lab-scale testing and manufacturing. Our team of experts gives you the confidence to apply the technology for your specific wastewater challenges.
