Uniform distribution of air and water even in extra-long lengths. The polymer matrix is corrosion-free. Click the button below to directly contact the supplier.

Filterworx Performance Filter

Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. Provides even backwash distribution to deep clean filter media.

Easy handling – snaps together for quick installation. Leopold Underdrains Thanks to Xylem. 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 on this site are submitted by users and are not endorsed by nor do they reflect the underdraln or opinions of COLE Publishing, Inc.

The design includes slots and orifices around the entire underdrain to help clean the filter media from every angle during the backwash process.

The bolt-down solution is engineered for reliability with an uplift resistance of over 15 psi. Precision-engineered 1 mm slots support media down to microns 1. September 13, Stellar Management.

Comments are moderated before being posted. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour. Physically rigid design reduces flexing and withstands pressures up to 15 psi 1 bar. 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. Suitable for wastewater plants, biologically active filters and more.

Both feature a unique water recovery channel for superior air scouring and water backwash performance. Can be designed for wall-feed applications as well as center flume, front flume and Leopold Flat Bottom flume.

More driving head results in longer filter run times. March 06, Towering Above the Competition. Air stability is improved with all orifices providing uniform and continuous airflow. The modular underdrain blocks are easy to handle and snap together for quick installation. Physically rigid design reduces flexing and withstands pressures up leipold 15 psi.

New at WEFTEC: Xylem Launches Underdrain with 360-Degree Backwash Capability

Company Profile Email Us. Self-cleaning technology removes sediment buildup in the underdrain over time. 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.


By washing percent of the media between laterals, the underdrain increases filter run times, reduces backwash water consumption and extends media filter undfrdrain, leading to lower operating costs and energy savings.

At WEFTEC this underrdain, Xylem highlighted its Leopold Type underdrain — a bolt-down underdrain system for greenfield projects and rehabilitation of water treatment filtration projects.

Leopold Type XA Underdrain

Durable reinforced polymer maximizes strength against harsh elements while reducing overall weight for easier transport and installation. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar.

Unserdrain are constructed of high-density polyethylene HDPE construction for strength and corrosion resistance. This eliminates media dead zones that can develop due to gaps in backwashing coverage. EPA LT2 rules on contaminants of emerging concern, and the rehabilitation of existing media filters. Reduces construction costs reducing vertical footprint by inches cm by eliminating gravel 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 IMS Cap eliminates the need for gravel thereby allowing for deeper media depth.
