This study describes the temporal and spatial variability of bacterial communities within a combined sewer system in England. Sampling was conducted over 9 months in a sewer system with intensive monitoring of hydraulic conditions. The bacterial communities were characterized by 16S rRNA gene-targeted terminal restriction fragment length polymorphism analysis. These data were related to the hyd...

abstract aims: turbidity in higher than standard levels, indicates failure in the water treatment plant. an electrochemical disinfection process takes place through electricity transition between two or more electrodes. this research aimed to determine the reaction rate of electrochemical process for purification of polluted water. materials & methods: this is a bench scale, experimental study ...

To explore the synergistic effects of modified biochar in purification herbicide-containing wastewater, effect addition on removal herbicide atrazine wastewater was verified by bags a small reed bed-constructed wetland laboratory. The results showed that sulfuric acid-modified could increase rate from 50% to 70%, and COD elimination 66.7% 86.7%. constructed bed improved efficiency total nitroge...

The environmental loading of steroid hormones contained in dairy wastes may cause an adverse effect on aquatic species. To better assess the potential risks of hormone contamination resulting from land application of dairy wastes, various steroid hormones were determined in a typical dairy waste disposal system. Quantitative methods using gas chromatography/mass spectrometry (GC/MS) were develo...

Constructed wetlands are engineered to duplicate the processes occurring innaturalwetlands. Themain purpose of structure is remove contaminants or pollutants from wastewater. wetland a new, creative, cost-effective, and green technology compared conventional treatment systems. Water hyacinth couldbe cultivated for wastewater utilised aid purification either industrial sewer water. Consequently,...

This study deals with the dairy wastewater treatment using laboratory scale vertical flow (VF) constructed wetlands <i>Canna indica</i> plantation over wetland beds due to phytoremediation capabilities. Three VF CWs (CW-A, CW-B and CW-C) each an area of 0.135 m2 filled gravel (CW-A: 20 mm; CW-B:10 mm gravel) sand (CW-C) receiving 0.04 m3 d-1 were operated for purification. Each unit...
