ANUBIX™ - B
 

GWE’s “work horse” most recent version is already the 7th generation UASB (Upflow Anaerobic Sludge Blanket) since its launch in 1979. Its constant improvement now allows for medium to high loading rates.



ANUBIX™- B can be used for most low to medium strength mainly soluble carbohydrate containing effluents, attaining amazing COD removal efficiencies, in some cases even up to 99%!

Main advantages of the ANUBIX™- B:

  • Fully developed and tested on a large variety of effluents
  • Low maintenance, robust and reliable no-nonsense system
  • Superior three-phase separator allows for granular or flocculent sludge operation
  • Gas-holder not required through integrated storage capacity
  • Steel or concrete construction of tanks
  • Capable of handling high loading rates
    (up to 15 kg COD/m3.d depending on the type of effluent)

Wastewater enters the reactor at the bottom via a special distribution system and leaves through a built-in three phase separator at the top which diverts the biogas and retains solids.

The modular separator units are built in stainless steel and GRP (Glass Reinforced Plastic), and are equipped with an additional cross-flow type parallel plate separator that ensures that even the smallest flocs of methanogenic sludge are retained.

This special feature furthermore allows for a fast start-up, even with non-granular seed sludge. The effluent leaves the reactor through the central collecting pipe.



Biogas is collected at the top and conveyed for either, further upgrading in e.g. a BIO-SULFURIX™and/or GASODRIX™, after which it can be fed to a CHP unit, alternatively it may directly feed into a boiler system for steam production. Excess biogas is sent to an emergency flare.
