The design includes slots and orifices around the entire underdrain to help clean the filter media from every angle during the backwash process. Superior air and water distribution for effective backwash, giving longer filter runs and lower operating costs. Uniform distribution of air and water even in extra-long lengths.

Precision-engineered 1 mm slots support media down to microns 1. Company Profile Email Us. Click the button below to directly contact the supplier. Physically rigid design reduces flexing and withstands pressures up to 15 psi 1 bar. 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 Universal Type S® Underdrain by Xylem

Type SL underdrain features a lower profile, making it ideal for shallow filters where greater filter media depth is desired. Both feature a unique water recovery channel for superior air scouring and water backwash performance.

Click Here To Download: The IMS Cap eliminates the need for gravel thereby allowing for deeper media depth. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar. Easy handling – snap together for quick installation.

Suitable for drinking water plants and desalination plants. March 06, Towering Above the Competition. The bolt-down solution is engineered for reliability with an uplift resistance of over 15 psi.

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

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 uncerdrain psi. Durable reinforced polymer maximizes strength against harsh elements while reducing overall weight for easier transport and 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.

The modular underdrain blocks are easy to handle and snap together for quick installation. Newsletter Sign Up Join 16, of your colleagues who already get great content delivered right to their inbox.

September 13, Stellar Management. Leooold technology removes sediment buildup in the underdrain over time. Type S underdrain is ideal for designs requiring longer laterals. Easy handling – snaps together for quick installation.

Provides even backwash distribution to deep clean filter media. This eliminates media dead zones that can develop due to gaps in backwashing coverage. Can be designed for wall-feed applications as well as center flume, front flume and Leopold Flat Bottom flume. 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.

Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs.

Leopold Type XA Underdrain

More driving head results in longer filter run times. Air stability is improved with all orifices providing uniform and continuous airflow. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour. Request more detailed information or literature. 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. The underdrain is compatible with all standard flume and air configurations. Both are constructed of high-density polyethylene HDPE construction for strength and corrosion resistance. 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.

The polymer matrix is corrosion-free.
