Services of material and product testing Thermal conductivity According to LVS ISO 8301-2001-A1-2011 Thermal insulation. Thermal resistance and determination of related properties in steady conditions. Device of thermal flow measurement. Determination of hygrothermal properties of materials Testing of materials in climate chamber, simulating different types of impact of environment on them. Services of biosystem laboratory Tests of biomethane potential (BMP) Measurements are made in small volumes (100 ml), average volumes and bioreactores (5L and 135L) with continious monitoring of environmental conditions and gas composition. BMP test takes 20-30 days, in the future results are planned to get faster, using mathematical models. Kinetics of biogas and biomethane formation Anaerobic fermentation is possible to do in bioreactors (5L and 135L), in real conditions researching optimal relation of raw materials, regimes of injection, changes of gas composition, pH stability, withstanding time of optimal substrate and other parameters. Composition analysis of gas and envioronment/digestate fermentation Concentrations of gas, volatile fatty acids, long chain fatty acids are analyzed during measurements, to determine processes in bioreactor. Determination of heavy metals in substrate and digestate (planned) It’s possible to determine both heavy metals in substrate and digestate (also other briought in samples from client ) and its method efficiency of concentration reduction.
