Aerobic Treatment Unit (ATU) System Design Tips And Operations Variables
1/23/2019
Providing a suitable environment for microorganisms to treat wastewater is what aerobic treatment units (ATUs) are all about. These advanced systems outshine alternatives on tight lots where there is no room for conventional treatment and on sites with poor soils, shallow vertical separation distances to limiting conditions, and horizontal setback restrictions. Some systems can be designed for the treatment of high-strength wastewater or where total nitrogen removal is required.
