The use of mass balance-based calculation of the net growth rate of each OTU individually exploits the known solids residence time of the activated sludge plant and thus may not be widely ...

A novel cement alternative using alum sludge enhances resistance to microbiologically influenced corrosion, improving ...

To fill this gap, an international team of researchers conducted an in-depth analysis of microbial interactions at elevated salinity in activated sludge systems. Biological treatment processes are ...

The researchers found that reducing the amount of KOH used by at least 50%, with a sludge-to-KOH ratio of 3:1 at a maximum temperature of 800 °C (1,472 °F) was optimal, producing a yield of 0.63 ...
