MOROCOMP (LIFE TCY05/MA000141) - Unit of Environmental ...

The ventilator system can operate X times per day for a duration of Y minutes per
hour. The maximum set values are Χmax = 24 times/day and Ymax = 10 minutes
while the minimum ones are Χmin = 0 times/day and Ymin = 0 minutes.
Programming the frequency and duration of the substrate’s hydration
The hydration system can operate X times per day for a duration of Y minutes per
hour. The maximum set values are Χmax = 2 times/day and Ymax = 15 minutes while
the minimum ones are Χmin = 0 times/day and Ymin = 0 minutes
4.3.2. Measuring the temperature of the substrate
The temperature of the substrate was being measured at regular time intervals
throughout the composting duration. For these measurements a microchip was used
(DATA LOGGERS MODEL 100 2K). The device was installed in the interior of the
bioreactor and was collected at the end of each composting trial and after the
collection and removal of the end product. The recorded temperature values were
obtained, using the software of the device. For comparison reasons and for the better
understanding of the temperature profile during the composting processes, additional
temperature measurements of the substrate have been performed using a portable
thermometer. These temperature values were recorded once per day at the same point
inside the bioreactor.
4.3.3. Measuring the moisture of the substrate
The moisture level was being recorded once per day for the duration of the
composting process. Six same weighted and representative samples were being
selected daily from inside the bioreactor. The final sample was formed after stirring
and mixing the six samples together to form a homogeneous material. From the
homogeneous material six separate samples were selected weighted and dried at
105°C for 12hrs. The dried samples were then placed inside a desiccator for cooling
and weighting. The moisture content was evaluated from the average value of the six
separate samples.
