Composting is an important tool for the treatment of the organic fraction of solid waste through the use of technologies that process the waste generated from agriculture, agribusiness, forestry, households, and also sludge ...

This paper has the objective of monitoring the biological activity of composting process of sewage sludge, sugarcane bagasse and ground coffee in a hermetic rotary reactor using the respirometric method in laboratory scale, ...

Despite several previous studies, a better understanding of the sewage sludge composting process is necessary. This study evaluates the use of an automated respirometer with hermetic rotary reactor (ARHRR) to evaluate O2 ...

This paper analyses the oxidation of covellite and molybdenite by Acidithiobacillus ferrooxidans strain LR using respirometric experiments. The results showed that both sulfides were oxidized by A. ferrooxidans, however, ...

The aim of this research was the development of a procedure to measure biological kinetics of organic matter oxidation and nitrification in constructed wetland, by using respirometric techniques. Columns simulating cores ...
