ANAMIX™ organic waste digester

The GWE ANAMIX™ is a completely-mixed form of anaerobic reactor, designed to maximize the contact between the biomass and the waste, to optimize digestion performance. One of the oldest digester configurations, it is also one of the best in terms of applicability to different wastes. No waste is too strong to employ the technology and with two different operating modes and many different forms of biomass retention, the ANAMIX™ is an extremely flexible process.

Construction Management

In an ANAMIX™ system, the wastewater (wastewater/sludge mixture) enters the reactor at the bottom and leaves at the top and includes an internal recycle loop which draws reactor contents from the opposite side of the entry. Proper mixing by means of a top-entry, multi-stage agitator ensures that the influent is in constant contact with the biomass for optimal mass transfer and conversion of organic content (COD) to biogas. Depending on the application besides the top entry mixers, other solutions can be applied, such as side entry mixers or jet mixers.

Key features of our ANAMIX™:

  • Low to medium loading rates;
  • No waste is too strong (organic content, COD). The system can handle sludge, slurries or other concentrated wastewaters;
  • Suitable for high fats, oil and grease (FOG) concentrations;
  • Can manage very high suspended solids (TSS) concentrations (> 25,000 mg/L TSS);
  • ANAMIX™ - M (mesophilic digestion: 35-40°C) suitable for high protein (nitrogen) content wastes;
  • ANAMIX™ - T (thermophilic digestion process: 45-55°C) suitable for low protein (nitrogen) content wastes.

Industries and applications: as a sludge digester (primary sludge, DAF floats, food production residuals); meat and fish processing, dairy products, confectionery, mixed food waste (see the GWE's RAPTOR® process), distillery, winery.
