Trickling pond

On the basis of the risk assessment, various possible remediation technologies were considered. Excavation of the entire area and off-site incineration was an unacceptably expensive option. For the soil remediation of the former trickling pond, an innovative site-specific strategy was... 

For the site of the trickling pond, a site-specific strategy for the remediation was established. Flighly contaminated hot spots were excavated to protect the groundwater. The applied biological treatment technology was tested in pilot scale on site. A feasibility study was done for the estimation of remediation time and TNT reduction which can be achieved by biological transformation. 

The four most common aerobic biological treatment processes are stabilization ponds, aerated lagoons, trickling filters, and activated sludge (see... 

Due to the focus of this work, other biological processes will also be mentioned. They include trickling filters, coating biological contactors, pond stabilization, anaerobic digestion, and biological nutrient removal.23 5... 

Different biological processes used for the treatment of wastes are activated sludge, aerated lagoons, anaerobic digestion, composting enzyme treatment, trickling filter, and waste stabilization ponds. 

The school was called Los Alamos, the daughter of its founder writes, after the deep canyon which bordered the mesa to the south and which was groved with cottonwood trees along the sandy trickle of its stream. Ashley Pond, the founder, had been a sickly boarding-school boy... 

Primarily, activated sludge processes and, less often, trickling filter processes are employed for aerobic biological treatment. In North America and Northern Europe, effluent purification is frequently carried out in aerated oxidation ponds. Recently, anaerobic treatment has become established, especially in paper mills processing recovered paper.
