Innovative New Wastewater Treatment Solutions Unveiled at WEFTEC 2012

Xylem Inc. (USA), a leading global water technology company recently attended the WEFTEC exhibition in New Orleans where they launched three new water treatment solutions into the North American market. Last year they launched new systems: Wedeco Duron, Sanitaire BioLoop oxidation ditch and Leopold I.M.S 1000 media retainer.

Ron Port, Head of Xylem’s Treatment Business said, “Energy efficiency is a key concern for customers as they seek to reduce costs and maximise the effectiveness of their operations. Our new, innovative solutions respond to our clients’ needs for optimal energy and cost efficiency, without compromising on performance and are designed to make our customers’ jobs as easy as possible. They are simple to install, require a limited amount of space and thanks to Xylem’s reliability, require minimal operating and maintenance costs.”

One of the new solutions Xylem have launched is their open channel ultraviolet (UV) disinfection system called WEDECO Duron. This has been designed to offer clean, safe treated wastewater that will minimise energy consumption. The WEDECO Duron is designed for mid-size to large open channel systems, and gets rid of the need for chemical based disinfection but also reduces the energy costs and space required. WEDECO Duron has been designed as the ideal fit for all medium to large size wastewater treatment plants that are looking for an environmentally friendly disinfection option that is easy to install, operate and maintain.

Xylem have also launched the Sanitaire BioLoop oxidation ditch, for biological wastewater treatment. This is a complete solution which will cut energy demands and costs by up to 50%. This efficient system involves a whole process approach including aeration, submersible mixers, blowers, monitoring and process control systems with sludge age control, all designed to provide a flexible, yet simple-to-operate system.

The Sanitaire BioLoop fine bubble diffused aeration is much more energy efficient than other aerators in the market and can be designed to accommodate stringent nutrient removal regulations for nitrogen and phosphorus. By combining Sanitaire aeration with the advanced mixing technology of Xylem’s Flygt mixers, the Sanitaire BioLoop delivers excellent life cycle cost benefits, reliable effluent quality and single source responsibility for both new and retrofit oxidation ditch systems.

Xylem has also engineered a new water filtration technology to replace support gravel in the wastewater market, making it the only media retainer available for wastewater. The unique, new Leopold I.M.S 1000 media retainer allows wastewater treatment plants to consistently deliver higher quality effluent than with support gravel due to increased media depth and available driving head. Suitable for use in wastewater plants, in GAC contactors, in biologically active filters and in the construction of filters for de-nitrification, the new Leopold I.M.S 1000 media retainer also costs less to install and operate. The Leopold I.M.S 1000 enhances Xylem’s media retainer range which already includes the Leopold I.M.S 200 for drinking water and comes backed with Leopold’s 80 plus years of reliability and expertise in water treatment.
