The Phoenix
Get closer to full-scale anaerobic digestion conditions with manual semi-continuous feeding, allowing you to top up the feed as much as you like. This reduces the shock loading effect from large sudden feeds, and produces more consistent gas production profiles. The effluent bottles allow digestate to be removed from the system, meaning it can be run continuously, with the same feed as full-scale AD plants — any total solids content works.
The Phoenix has six 2L reactors, which enables multiple feedstocks to be tested, or repeat digesters to be run. It provides the volume for enough gas production for frequent gas analysis, whilst maintaining a small footprint to conveniently fit in any lab.
Open source data logging
Our open source Arduino data logger records and stores the gas production data measured by the gas flow meter. When an event happens in the gas flow meter, a reed switch circuit is closed which is logged by the data logger. The BMP280 pressure sensor and thermocouple inform the data logger to automatically convert any gas volumes to STP. Data is easily extracted at any time through USB connection with any computer.
Manual feeding
Manually feed as frequently as you like without compromising the anaerobic setup. You can reduce the shock to the digester that comes from large irregular feeds. Simply remove the gas-tight cap, insert your feed and put the cap back on.
6 reactors
Have multiple continuously-run systems at once. Use them to test various feedstocks or have repeat digesters to verify your results.
Any feedstock
Simple and reliable, manual feeding gives you control over your digester's feedstock intake, allowing you to customise the process to your requirements. Use any type of feedstock including total solids content up to 100%, by using the manual feeding port.
Inside the Phoenix
Feeding Port
Large cap is removed when feeding. Anaerobic conditions are maintained.
2L Reactor
Stainless steel reactor provides environment for anaerobic digestion.
1L Effluent Bottle
The easily removable effluent bottle collects the excess digestate to avoid pressure build ups and spillages.
Mixer motor
Each reactor comes with a 20 rpm motor which constantly mixes the inside of the reactors.
Water Bath
Grant water bath reliably controls temperature, from ambient temperature up to 85°C.
