ANUBIX™ - C
 
GWE developed the ANUBIX™- C next to the ANUBIX™-B for the treatment of more concentrated wastewaters. The recycle system resembles that of digesters, in combination with sludge separation from the final effluent over a lamella separator. The internal recirculation feature of the ANUBIX™-C allows for immediate dilution whilst at the same time saving space.



ANUBIX™- C can be used for most medium to high strength mainly soluble carbohydrate containing effluents, attaining amazing COD removal efficiencies.

Main advantages of the ANUBIX™- C:
  • 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 medium loading rates (up to 8 kg COD/m3.d depending on the type of effluent)
  • Suitable for wastewaters with COD (Chemical Oxygen Demand) values of up to around 70,000 mg/l.

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 Polyester), 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 moreover allows for a fast start-up, even with low quality, non-granular anaerobic 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.
