![]() Ninety liter (90 L) anaerobic digesters (anaerobic filters) were constructed from PVC pipe. The digesters were filled with lava rock. A thermocouple is placed in the center of each digester to be used in controlling temperature. Each digester is controlled by a datalogger by reading temperature and turning on or off pumps to circulate water around digester maintaining temperature at 35 oC. |
