Increased concerns over fluvial carbon losses from deforested tropical peatlands
Over 20% more carbon could be being released by tropical peatlands than previously estimated, a new study suggests. The research highlights the large quantities of carbon lost to rivers from deforested and degraded peatlands in Indonesia, in addition to carbon released as CO2 gas. Peatlands are an important carbon store and the peat swamp forests of south-east Asia have experienced excessive ...

Sky high – Fast detection of total organic carbon peak loads
Normally, production facilities have low waste water discharge levels, mostly within the range of 1,000 ppm TOC (total organic carbon). However, occasionally the installation can suffer failures or process disturbances take place. In this case, the range could very well reach a level of up to 50,000 ppm. If these go unnoticed, besides the expenses of waste water treatment processing, energy ...
