<p>Importing text file</p> <p><b>Nová stránka</b></p><div>:Slovak term: [[Slovenský termín]]<br /> # Wastewater treatment step that follows primary treatment (WHO 2006).<br /> <br /> ==Explanation==<br /> Involves the removal of biodegradable dissolved and colloidal organic matter using<br /> high-rate, engineered aerobic biological treatment processes (WHO 2006).<br /> <br /> Secondary treatment is the second step in most publicly owned waste treatment systems in<br /> which bacteria consume the organic parts of the waste. It is accomplished by bringing<br /> together waste, bacteria, and oxygen in trickling filters or in the activated sludge process.<br /> This treatment removes floating and settlable solids and about 90 percent of the<br /> oxygen-demanding substances and suspended solids. Disinfection is the final stage of<br /> secondary treatment (US EPA 1989).<br /> <br /> ==Example==<br /> Examples of secondary treatment include activated sludge, trickling filters, aerated lagoons<br /> and oxidation ditches (WHO 2006).<br /> <br /> ==References==<br /> * US Environmental Protection Agency (1989) Glossary of Environmental Terms and Acronym List.
