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

September 13, Stellar Management. Suitable for wastewater plants, biologically active filters and more. Request more detailed information or literature. 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.

Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. Can be designed for center and front flumes.

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

With lateral lengths over 40 feet, it is suited for long filter runs and retrofits of existing filters. Easy handling – snap together for quick installation. Comments are moderated before being posted.

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. The IMS Cap eliminates the need for gravel thereby allowing for deeper media depth. Self-cleaning technology removes sediment buildup in the underdrain over time. Leopold Underdrains Thanks to Xylem.

The underdrain is compatible with all standard flume and air configurations. This eliminates media dead zones that can develop due to gaps in backwashing coverage. Superior air and water distribution for effective backwash, giving longer filter runs and lower operating costs. Leopold — A Xylem Brand. Air stability is improved oeopold all orifices providing uniform and continuous airflow. Both feature a unique water recovery channel for superior air scouring and water backwash underdraln.

Easy handling – snaps together for quick installation. The design includes slots and orifices around the entire underdrain to help clean the filter media from every angle during the backwash process. Company Profile Email Us. More driving head results in longer filter runs.

The bolt-down solution is engineered for reliability with an uplift resistance of over 15 psi. It includes an innovative degree backwash capability designed to boost efficiency by up to 20 percent.

The Type underdrain helps solve challenges in biologically active filtration systems, indirect and direct potable reuse applications, new drinking water applications addressing the U.

Durable reinforced polymer maximizes strength against harsh elements while reducing overall weight for easier transport and installation. More driving head results in longer filter run times. Provides even backwash distribution to deep clean filter media. Type S underdrain is ideal for designs requiring longer laterals. Best uplift resistance – withstands uplift pressures up to 30 psi 2 bar.


Precision-engineered 1 mm slots support media down to microns 1. Handles for quick and easy installation, and snaps together for quick installation. Get General articles, news and videos right in your inbox!

The polymer matrix is corrosion-free.

The modular underdrain blocks are undsrdrain to handle and snap together for quick installation. 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.

Leopold Type XA Underdrain

unserdrain 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. Uniform distribution of air and water even in extra-long lengths.

Physically rigid design reduces flexing and withstands pressures up to 15 psi. Type SL underdrain features a lower profile, making it ideal for shallow filters where greater filter media depth is desired. Click Here To Download: Suitable for drinking water plants and desalination plants.

Can be designed for wall-feed applications as well as center flume, front flume and Leopold Flat Bottom flume. Both are constructed of high-density polyethylene HDPE construction for strength and corrosion resistance.
