A completely closed system (oxygen-free) that biologically treats waste with naturally occurring organisms.
Anaerobic digestion is typically for a larger scale application, and has a better control for the environment. Aquastore tanks can be used for Mesophyllic Digestion or Thermophyllic Digestion and also come along with a variety of pressurized roof options.
Mesophyllic Digestion – Anaerobic digestion process, normally between 35-40 °C (94-104 °F).
Thermophyllic Digestion – Anaerobic digestion process at elevated temperature, normally between 60-80°C (140-176°F)
