We Provide The Best AnMBR Solutions for Industrial Applications

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.

Why anaerobic wastewater treatment

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.

Anaerobic vs. Aerobic treatment

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…)

External AnMBR

For the industries producing high-load wastewater – such as dairy, distilleries, slaughterhouses, confectionery, fish processing… – our external solutions for AnMBR are often the best choice. The tubular UF modules are coupled to a simple complete-mix digester, allowing the operation with high organic loads (OLR up to 8 – 10 kg COD/m3·day). The UF membranes ensure the retention of the biomass within the anaerobic digester and brings significant improvement in the digestion process, making it more robust and increasing the biogas production. More than 98% COD removals can be achieved in the single-step AnMBR – in contrast with 75 – 90% removal with conventional anaerobic technologies. As a result, post-treatment is avoided in most cases. The UF permeate can be suitable for reuse, or alternatively, it can be fed to a reverse osmosis system for producing high-quality water.

Advantages over conventional granular technologies:

Better effluent quality

Biogas production

Robust

Low Sludge Production

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.

Case Study

AnMBR | Dairy Industry​

External AnMBR system in USA for dairy, one of the largest users of wastewater out of all major industries.

The challenge:

  • To find an efficient process to generate electricity
    and heat from whey and other high strength liquid
    waste, left over from the manufacturing of cheese and
    yogurt from cow’s milk.
  • To further treat anaerobic industrial wastewater
    discharge with high levels of solids before discharging
    to a nearby river.
