New at WEFTEC: Xylem Launches Underdrain… | Treatment Plant Operator

leopolx The bolt-down solution is engineered for reliability with an uplift resistance of over 15 psi. Get General articles, news and videos right in your inbox! The underdrain is compatible with all standard flume and air configurations. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour.

Click the button below to directly contact the supplier. The design includes slots and orifices around the entire underdrain to help clean the filter media from every angle during the backwash process. At WEFTEC this year, Xylem highlighted its Leopold Undeerdrain underdrain — a bolt-down underdrain system for greenfield projects and rehabilitation of water treatment filtration projects.

Precision-engineered 1 mm slots support media down to microns 1.

Leopold: Products – Media Filtration

Both feature the dual parallel lateral design pioneered by Leopold, ensuring uniform distribution of water and air at each dispersion orifice opening even in extra long lengths.

Can be designed for wall-feed applications as well as center flume, front flume and Leopold Flat Bottom flume. Undrdrain includes an innovative degree backwash capability designed to boost efficiency by up to 20 percent.

Easy handling – snaps together for quick installation. The Type underdrain helps solve challenges in biologically active filtration systems, indirect and direct potable reuse applications, new drinking water applications addressing the U.

Comments are moderated before being posted. Both feature a unique water recovery channel for superior air scouring and water backwash performance. With lateral lengths over 40 feet, it is suited for long filter runs and retrofits of existing filters. Suitable for wastewater plants, biologically active filters and more.

Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. By washing percent of the media between laterals, the underdrain increases filter run times, reduces backwash water consumption and extends media filter life, leading to lower operating costs and energy savings.

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.


September 13, Stellar Management. Uniform distribution of air and water even in extra-long lengths. Handles for quick and easy installation, and snaps together for quick installation.

Both are constructed of high-density polyethylene HDPE construction for strength and corrosion resistance. March 06, Towering Above the Competition.

Easy handling – snap together for quick installation. The polymer matrix is corrosion-free. More driving head results in longer filter run times. Request more detailed information or literature. Leopold Underdrains Thanks to Xylem. Air stability is improved with all orifices providing uniform and continuous airflow. Click Here To Download: Type SL underdrain features a lower profile, making it ideal for shallow filters where greater filter media depth is desired.

Suitable for drinking water plants and desalination plants.

Undersrain technology removes sediment buildup in the underdrain over time. Reduces construction costs reducing vertical footprint by inches cm by eliminating gravel support allowing for the same media depth in less vertical space.

The IMS Cap eliminates the need for gravel thereby allowing for deeper media depth. Type S underdrain is ideal for designs requiring longer laterals. Superior air and water distribution for effective backwash, giving longer filter runs and lower operating costs. EPA LT2 rules on undrrdrain of emerging concern, and the rehabilitation of existing media filters.

Reduces construction costs replacing up to 14 inches 36 cm of gravel media support allowing for the same media depth in less vertical space.
