Conventional wastewater treatment consists of a combination of physical, chemical, and biological processes and operations to remove solids, organic matter, and, sometimes, nutrients from wastewater. To increase the treatment level, general terms used to describe different degrees of treatment are preliminary, primary, secondary, and tertiary, and advanced wastewater treatment. In some countries, disinfection to remove pathogens sometimes follows the last treatment step.
