Xylem Solution: Wastewater Aeration

Diffused aeration is the process of adding air into wastewater to support aerobic biodegradation of organic materials. It’s a core element of secondary treatment processes, including conventional activated sludge processes. Xylem Sanitaire brand aeration solutions are designed to reduce equipment capital and life cycle costs.
