Leopold Universal Type S® Underdrain by Xylem

Leopold — A Xylem Brand. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar.

Handles for quick and easy installation, and snaps together for quick installation. At WEFTEC this year, Xylem highlighted its Leopold Type underdrain — a bolt-down underdrain system for greenfield projects and rehabilitation of water treatment filtration projects.

Durable reinforced polymer maximizes strength against harsh elements while reducing overall weight for easier transport and installation. The design includes slots and orifices around the entire underdrain to help clean the filter media from every angle during the backwash process. The Type underdrain helps solve challenges in biologically active filtration systems, indirect and direct potable reuse applications, new drinking water applications addressing the U.

Physically rigid design reduces flexing and withstands pressures up to 15 psi 1 bar. Both are constructed of high-density polyethylene HDPE construction for strength underdrani corrosion resistance.

Physically rigid design reduces flexing and withstands pressures up to 15 psi.

Can be designed for center and front flumes. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour. The IMS Cap eliminates the need for gravel thereby allowing for deeper media depth.

Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. Type SL underdrain features a lower profile, making it ideal for shallow filters where greater filter media depth is desired. Precision-engineered 1 mm slots support media down to microns 1. Both feature a unique water recovery channel for superior air scouring and water backwash performance.

Leopold Universal Type S® Underdrain by Xylem

Suitable for wastewater plants, biologically active filters and more. Self-cleaning technology removes sediment buildup in the underdrain over time. The lsopold solution is engineered for reliability with an underdrai resistance of over 15 psi. Leopold Type S technology underdrain is designed to provide uniform distribution of wash water and air to clean every corner of the filter without media upset.
