EKO GEA's breakthrough process for AD and biogas production

If your goals are maximising biogas for energy, completely eliminating waste, or generating rich fertiliser for crop vitality, EKO GEA provides a full range of solutions. It can be adopted by existing AD Plants using a dosing mechanism and protocol or added as part of the process to build into new AD Plants.

BCx makes a Difference

  • Volatile fatty acid destruction is enhanced and elements harmful to the AD process are buffered preventing them affecting the digestion process;
  • BCx breaks down VFA’s to feed beneficial microbes the simple organic acids they require;
  • BCx allows microbes to flourish in waste and promotes “good microbes” over harmful pathogenic microbes;
  • As a result, BCx improves the digestion environment, speeds the digestion process and CH4 concentration;
  • By increasing VSD, BCx makes more carbon available whilst increasing the available C/N
  • At the same time it reduces BOD/COD, ammonia (NH3 becomes NH4) and H2S (H2S becomes elemental sulphur).

Flexibility

Our complete process can complete the digestion process to fully clean waste, or halt the process to provide highest-quality NPK nutrients for land application – all on a sliding scale – depending on what is desired, when.

Speed

A 12-day process at mesophilic temperatures, or an 8-day process at thermophilic, our system dramatically reduces retention time.  This means smaller tanks and lower capital costs.

More energy

Our complete process makes biogas at 80+% methane – unprecedented in the industry. More methane = more profit!

No organic digestate

If the headaches of digestate storage, transport and marketing is your issue, we can digest organic content down to a very small amount of completely mineralised, sand-like material which requires no further treatment.

Clean water

Effluent from our process is grey water suitable for direct release to watercourses, irrigation or re-use, so full cleaning and waste elimination is a genuine option.

Pre – Treatment of AD Feedstock

​A mechanical ‘pre-treatment’ which micronises waste for faster, more complete digestion It emulsifies, liquefies and disperses nutrients for easy consumption by microbes. An optional mechanical concentrator treatment provides solids-separation before or after AD.

BioComplex – the ideal prebiotic.

Our proprietary additive builds vast populations of diverse anaerobic microbial populations. It feeds and protects anaerobic “workers” providing the following benefits;

  • Ion exchange – essential for sound AD and something no other process offers. Provides immediate HS & ammonia reduction and buffers free ion inhibitors.
  • Ideal nutrient profile for microbes – oligosaccharides and a full range of trace elements support the growth of vast microbial “worker” populations
  • Physical gelation property disperses nutrients in digesters, further supporting microbial proliferation, creating small, healthy colonies over large, metabolite-toxified colonies.

Biomedia

Our proprietary biomedia houses and holds microbes in a fixed film. It is unlike conventional digesters which give up important microbes with every digestate release.

Biomedia is self-cleaning and never needs re-charging or replacement

The result is an AD Plant which is smaller, faster, greener, and highly stable. If you could look inside our digesters and compare them to conventional processes.

Combining robust engineering with sound microbiology is at the heart of everything we do.
