Mixing and Biological Process Solutions

Xylem's EnviroMix patented technologies consistently reduce energy consumption, simplify maintenance, and optimize process conditions, enabling highly scalable and flexible operations.

Combining patented, proprietary technology with extensive biological process expertise, Xylem’s EnviroMix product line delivers mixing and process control solutions that enable plants to address secondary treatment issues such as biological phosphorus removal, carbon management, mixing limited inefficiencies, denitrification, and more. Our principal markets are municipal wastewater treatment, industrial wastewater treatment, municipal water treatment, potable water storage mixing, and industrial process mixing.

EnviroMix Technologies

Xylem’s EnviroMix innovative solutions harness the power of energy-efficient mixing in a wide variety of water and wastewater treatment applications. Our mixing and process technologies integrate intelligent, user-friendly controls that provide customers with the performance they expect at the lowest life cycle cost. From optimizing nutrient removal to enhancing volatile solids destruction to maximizing mixing efficiency, our solutions are designed with our customers forefront of mind.

The system is surprisingly even more simple and easy to take care of than I expected. The equipment itself [is] really good.
