Wastewater Treatment: A Biological Process
Biological Wastewater Treatment:
Biological wastewater treatment is the most common method to treat wastewater. Microorganisms found in activated sludge help to break down biodegradable matter within wastewater. Activated sludge contains a variety of microorganisms such as bacteria, protozoa, metazoa, filamentous bacteria and algae. These microorganisms feed on the organic matter, breaking it down (Theobald, 2014). The composition of microorganisms within the activated sludge is vital, as the presence or absence of certain microorganisms can indicate the overall health and efficiency of the wastewater treatment process.
