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

Uderdrain 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. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar.

It includes an innovative degree backwash capability underdgain to boost efficiency by up to 20 percent. Click Here To Download: Leopold — A Xylem Brand. 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.

Self-cleaning technology removes sediment buildup in the underdrain over time. Comments on this site are submitted by users and leopolv not endorsed by nor do they reflect the views or opinions of COLE Publishing, Inc. Physically rigid design reduces flexing and withstands pressures up to 15 psi 1 bar. Superior air and water distribution for effective backwash, giving longer filter runs and lower operating costs.

Both feature a unique water recovery channel for superior air scouring and water backwash performance. Reduces construction costs replacing up to 14 inches 36 cm of gravel media support allowing for the same media depth in less vertical space.

With lateral lengths over 40 feet, it is suited for long filter runs and retrofits of existing filters. The modular underdrain blocks are easy to handle and snap together for quick installation. The bolt-down solution is engineered for reliability with an uplift resistance of over 15 psi.

Suitable for drinking water plants and desalination plants. At WEFTEC this year, Xylem highlighted its Leopold Undererain underdrain — a bolt-down underdrain system for greenfield projects and rehabilitation of water treatment filtration projects.

Can be designed for center and front flumes.

The polymer matrix is corrosion-free. Easy handling – snap together for quick installation. Reduces construction costs reducing vertical footprint by inches cm by eliminating gravel support allowing for the same media depth in less vertical space. Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. Handles for quick and easy installation, and snaps together for quick unxerdrain.


Leopold® Type XA™ Underdrain

The Type underdrain helps solve challenges in biologically active filtration systems, indirect and direct potable reuse applications, new drinking water applications addressing the U. Air stability is improved with all orifices providing uniform and continuous airflow. September 13, Stellar Management. EPA LT2 rules on contaminants of emerging underdraij, and the rehabilitation of existing media filters.

Easy handling – snaps together for quick installation. March 06, Towering Above the Competition. Both are constructed of high-density polyethylene HDPE construction for strength and corrosion resistance.

Type S underdrain is ideal for designs requiring longer laterals. Physically rigid design reduces flexing and withstands pressures up to 15 psi. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour. This eliminates media dead zones that can develop due to gaps in backwashing coverage. Uniform distribution of air and water even in extra-long lengths.
