What type of component is an ATU in a wastewater system?

An ATU, or Advanced Treatment Unit, is primarily a treatment component designed to enhance the processing of wastewater. The main function of an ATU is to provide additional treatment beyond what a conventional septic system offers. It utilizes innovative technology to improve the quality of effluent before it is discharged into the environment or sent to a leach field.

By employing processes such as aeration, filtration, and sometimes chemical treatment, an ATU effectively reduces pollutants and harmful pathogens in the wastewater, making it suitable for safe disposal or further use. This focus on treatment is crucial for maintaining environmental health and ensuring compliance with regulatory standards for wastewater management.

In contrast, components that are categorized as storage or transport primarily deal with holding wastewater or moving it from one location to another rather than processing it. This distinction clarifies why the function of an ATU aligns more closely with treatment than with storage or transport.
