Xylem’s Sanitaire brand provides complete biological wastewater treatment solutions for public utility and industrial applications. The Sanitaire comprehensive offering includes diffused aeration, sequencing batch reactors, oxidation ditches and state-of-the-art controls that drive efficient operations. Sanitaire is regarded as a leading brand in diffused aeration, which is a process that introduces air into a liquid, providing an aerobic environment for degradation of organic matter. Fine-pore diffusion of air is highly competitive due to its high oxygen transfer efficiency and lower energy costs. Sanitaire wide-band aeration systems are used in applications such as grit chambers and sludge that require non-clogging, maintenance-free systems. In 2013, Xylem launched the Sanitaire OSCAR process performance optimization system. When combined with Sanitaire advanced aeration systems, Xylem was able to deliver 65 percent energy savings to the operators of the Sterno, Sweden wastewater treatment plant.

Industries & Applications

Xylem offers a range of advanced wastewater and water solutions to help operators around the world achieve their required water effluent while delivering optimal performance, reliable operations and substantial energy savings no matter what industry or application. Working with customers, Xylem listens, learns, and adapts to local environments, ensuring the best possible design, customized to meet their specific needs. Below are some recommended industries and applications.

Municipal Wastewater

Municipal Wastewater

Harnessing the power that nature uses to cleanse the rivers and streams – air, microbes, gravity, light – the wastewater industry has revolutionized sanitation and brought health to their communities, rivers, streams, lakes and oceans. Through Xylem’s broad portfolio and expertise, customer needs are evaluated and the right solution provided with low life cycle costs. When the water leaves the plant, it is no longer wastewater, but a highly valuable resource.

Food & Beverage

Food & Beverage

With global population continuing to grow, feeding the world sustainably is a worldwide challenge. Water is at the center of this concern, as food production is the largest single consumer of water. Reducing the water footprint of food production is a central goal of the food and beverage industry. Xylem can assist in optimizing and managing every stage of a production facility’s water cycle. Customers utilize the complete water cycle solutions, such as energy efficient Flygt pumps to transport water throughout the facility, along with industry-leading Leopold filtration technologies, Sanitaire biological treatment and Wedeco disinfection and oxidation systems.



From feedwater, through internal treatment to generate pharmaceutical grade water, to final discharge, water is critical to pharmaceutical manufacturing. Treatments must meet the standards of the relevant pharmacopeias for the intended use of the water, with different pharmaceutical grades requiring different treatments from purified water (PW) to highly purified water (HPW) to the highest purity of water for injection (WFI). With Xylem treatment processes, safe, sustainable water practices can be achieved throughout the manufacture and through final discharge.

About Sanitaire

About Sanitaire

Sanitaire is the world leader in diffused aeration and advanced biological treatment technologies. Beginning in 1967, Sanitaire products have been used to create innovative wastewater treatment solutions for municipal and industrial wastewater treatment applications. Sanitaire equipment and technologies are the industry standard and have been installed in thousands of communities and industries throughout the world.

Established in 1967, Xylem’s Sanitaire brand provides biological wastewater treatment solutions for municipal and industrial applications. Sanitaire delivers a comprehensive offering that includes diffused aeration, oxidation ditches, membrane bioreactors (MBR), sequencing batch reactors (SBR), drum filters, and state-of-the-art controls that drive efficient operations. 

Sanitaire is regarded as a leading brand in diffused aeration, which is a process that introduces air into a liquid, providing an aerobic environment for degradation of organic matter. The broad selection of diffusers available including membrane, ceramic and coarse bubble, has been proven over time with over 22 million units installed worldwide. Xylem’s extensive applications expertise is available to ensure that both the right product is selected and the design is optimized for long-term reliability and low cost of ownership. 

Sanitaire wide-band aeration systems are used in applications such as grit chambers and sludge that require non-clogging, maintenance-free systems.

Combining Sanitaire diffused aeration, Flygt submersible mixing and overall process application, as well as instrumentation and process control in both new and retrofit applications, Xylem’s Sanitaire Bioloop oxidation ditch delivers up to 50% better energy efficiency, while remaining adaptable to a wide range of flow and loading conditions. 

Xylem’s Sanitaire MBR process combines Sanitaire diffused aeration, Flygt submersible mixing and pumps, WTW and MJK instrumentation, and unique process knowledge with Tier 1 membrane products available in the market. The result of this flexible biological design, and the complete removal of suspended solids from the treated water by ultrafiltration membranes, is superior effluent quality to meet discharge requirements. 

The Sanitaire ICEAS Advanced SBR is a continuous flow biological treatment system that provides multiple advantages versus conventional activated sludge and other SBRs by bringing together process, aeration, decanting, and control in a single treatment tank. Fully automated, it includes a completely integrated process design consisting of the aeration system, blowers, pumps, mixers, effluent decanters, monitoring and control equipment, and a comprehensive process control system.

The Sanitaire OSCAR process performance optimizer provides real-time wastewater process measurement and control to optimize operations. Combining the monitoring capability of the most advanced probes and control systems for aeration and Solids Retention Time (SRT), OSCAR reduces energy consumption while stabilizing the treatment process and maintaining effluent quality.
