Calibration laboratory for acoustics and vibration

 

1) Calibration Laboratory for Acoustics and Vibration is the place where the national primary standards of sound pressure in air, in water, and of vibration acceleration are maintained. Here all the procedures required for calibration of sound level meters, sound calibrators, microphones and underwater sound and vibration measuring instrumentation are carried out. In this way, the traceability in accordance with the national standards that ensure the units of measure in compliance with the International System of Units (SI) is provided.

Physical-chemical laboratory

 

 

1) Measurements in the process of anaerobic and aerobic digestion of waste material (solid or liquid) and measurements done for the purpose of characterization of waste material, wastewater, sludges and SRF (by measuring the process parameters: temperature, and by continuous measurement of the composition of the produced biogas, wastewater, or waste subjected to digestion);/ Preliminary evaluation of the biogas production potential of waste material. During characterization of waste material it is necessary to determine the composition of the waste material, wherein the carbon content and biological activity of the waste material –the real dynamic respiration index – are considered as the most important parameters. Some other parameters are also measured: dry matter and ash in the waste material, nitrogen content, pH value; / After the methane exhaustion by anaerobic or aerobic digestion, the composition of the residual waste material –digestate is determined.
