The objective of this research is to evaluate the performance of macrophyte waste stabilization pond system for municipal wastewater collected from Taxila (Pakistan). A model of macrophyte waste stabilization pond system was operated for six trials with each trials comprising different detention times that is 3, 5, 7 and 10 days, respectively. For the treatment, locally available macrophyte (wa...

A waste stabilization pond was suspected of causing fecal contamination to Holt Branch, a tributary of Juniper Creek, near Byron, Georgia. We used ribotyping, a genotypic (DNA-based) bacterial source tracking (BST) method, to match Enterococcus faecalis isolates from Holt Branch and the waste stabilization pond. Fecal enterococci in the effluent from the waste stabilization pond averaged 13,863...

One of the indexes of stabilization pond is the presence of coliform bacteria in water and wastewater. This study aimed to determine the effect of solar light on coliform variations in stabilization pond. In this experimental study, the effect of light, pH (<7, 7.1–8, 8.1–9), and temperature (10 ºC and 30 ºC) on facultative stabilization pond was studied for six months. The sampling was accompl...
