Xylem announces Leopold Type 360 with backwashing capability

Xylem now offers the Leopold Type 360 underdrain, a bolt down underdrain system for greenfield projects and water treatment filtration rehabilitation projects. The underdrain system has a design concept where backwash water flows in a 360-degree pattern, increasing efficiency by up to 20%. It has an uplift resistance above 15 psi and can withstand most events like hydraulic surges. The Leopold Type 360 features slots and orifces on the top, sides, and bottom of the underdrain block to clean filtration media, eliminating media dead zones. 

The Type 360 underdrain is compatible with all standard flume and air configurations, and with lateral lengths over 40 feet, it is ideal for long filter runs and retrofits of existing filters. The modular underdrain blocks snap together for quick and simple installation.
