Wastewater Aerobic Treatment Unit (ATU) is designed to provide efficient and reliable treatment for residential wastewater. Part of the Fixed Integrated Treatment Technologies (FITT) line, it employs the Fixed Activated Sludge Treatment (FAST) method, using fixed film media to encourage microbial growth for the breakdown of organic materials. The system is powered by a remote-mounted blower that helps introduce oxygen into the treatment module, ensuring optimal circulation. Known for their reliability and environmental compliance, MicroFAST systems are often certified under NSF/ANSI Standard 40, meeting EPA secondary effluent standards.
