Pilot units

• Continuous operation bioreactors for biogas production from agro-livestock waste

Continuous and Full Mixing Reactor (CSTR) for Anaerobic and Aerobic Digestion (30 lt & 5lt) with the following modifications if needed:

  • Fixed Bed Reactor (PBR)
  • Sludge Upward Flow Reactor (UASB)

Each reactor consists of a cylindrical stainless steel container, with an outer casing for heating and cooling. It has a stirrer, gas and liquid sampling points, as well as meters of operating parameters.

Analytical equipment

The Laboratory in Ptolemaida supports the Institute's research work by performing and evaluating analyses tests on solid fuel samples including biomass and solid recovered fuels (SRF). Having as a target the improvement of its services, from the end of 2013, the laboratory applies a quality management system in accordance with the requirements of ELOT EN ISO / IEC 17025 (Certificate No. ESYD 894). In addition, the operation of the Standard Chemical Laboratory of Northern Greece of PPC SA is supported.

Below, an Indicative list of laboratory instruments is given:

• Mercury analyzer

This instrument is an atomic absorption spectrometer with a mercury lamp, suitable for the analysis of solid, liquid and gaseous samples. It does not require special sample pretreatment and the analysis is completed in a short time (<10 min) and with high accuracy. The required operating range is about 30 ppt to 10 ppm.

Equipment for site measurements

• UAV - Drones with adapted metering equipment and high resolution camera

Unmanned Aircraft (UAV) - Drone UAV with adapted metering equipment suitable for the characterization of ambient air quality.
