Anaerobic Digestion

Anaerobic Digestion is one of the main processes which produces renewable energy in the form of biogas. This process involves the treatment of wastewater and organic solid wastes such as municipal, food, agriculture crop, animal waste and a variety of other wastes like sewage sludge, converting the organic portion to biogas.

In order to perform this process and for anaerobic plants to operate effectively they require a variety of nutrients for the micro-organisms to grow and function properly. However, it is often the case that anaerobic digesters and biogas plants are lacking in these vital micronutrients which means they do not work at their optimum. This can lead to poor COD and/or organic solids removal, elevated VFA levels, bacterial slime production, poor microbial growth and poor granulation in UASB type reactors.

To combat these potential anaerobic conditions, OMEX has developed a range of bio available micronutrient solutions, called Nutromex TEA (Trace Element Additives), formulated to optimise microbial performance in anaerobic digesters, wastewater treatment and biogas plants.

Key Benefits

  • Increased biogas production
  • Increased methane content in biogas
  • Reduced digester VFAs (Volatile Fatty Acids)
  • The trace elements are 100% bioavailable in solution
