Abstract: This paper investigates the treatment of chromium (Cr) contaminated industrial sludge from a tanning process with ultrasound to enhance the sludge settling ability and dewatering ability.

Interaction studies revealed that pH-induced flocculation and metabolically active microorganisms were involved in sewage sludge mediated microalgae settling. The anaerobic digestion of ...

There are places where the Earth's inner rumblings burble to the surface — like Iron Spring, located just outside the bustling town of Manitou Springs in central Colorado. Every few seconds, a ...

2009). Therefore, an evaluation of the specific methanogenic activity (SMA) of an anaerobic sludge becomes an important analysis for monitoring the process (Chaiprasert et al. 2003). The upflow ...

Carbon County has taken a stand in the fight against using sewage sludge as a fertilizer. Earlier this month, the board of commissioners sent a letter to Gov. Josh Shapiro, stating that the county is ...
