There are numerous international laws, ordinances, and regulations that impose certain environmental conditions necessary to guarantee a certain standard of quality.
In this context, instrumental analysis becomes a useful tool to measure the state of these conditions.
One possible application is the analysis of sewage sludge generated by wastewater treatment plants. In recent years, they have become the subject of increased attention in light of their potential to improve soil properties and provide important supplements of nutrients and trace elements essential for plant growth.
Knowing the parameter of TOC (Total Organic Carbon) is essential to determine the total concentration of organic carbon and then the organic pollution, which impedes the anaerobic digestion process, limiting the nitrogen enrichment of the subsoil.
The VELP CN 802 elemental analyzer is a complete and accurate solution for the determination of nitrogen and carbon content, including total organic carbon (TOC), in the environmental sector.
