With lateral lengths over 40 feet, it is suited for long filter runs and retrofits of existing filters. 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 leopolc energy savings. The modular underdrain blocks are easy to handle and snap together for quick installation.
Durable reinforced polymer maximizes strength against harsh elements while reducing overall weight for easier transport and installation.
The polymer matrix is corrosion-free. Request more detailed information or literature. Superior air and water distribution for effective backwash, giving longer filter runs and lower operating costs. The IMS Cap eliminates the need for gravel thereby allowing for deeper media depth.
Type S underdrain is ideal for designs requiring longer laterals. Precision-engineered 1 mm slots support media down to microns 1. Provides even backwash distribution to deep clean filter media.
September 13, Stellar Management. Both feature a unique water recovery channel for superior air scouring and water backwash performance. The design includes slots and orifices around the entire underdrain to help clean the filter media from every leoplld during the backwash process. EPA LT2 rules on contaminants of emerging concern, and the rehabilitation of existing media filters.
Leopold Universal Type S® Underdrain by Xylem
Company Profile Email Us. Physically rigid design reduces flexing and withstands pressures up to 15 psi 1 bar. The underdrain evacuates filtered water from the filter during the filter run and introduces water and air during backwashing and air scour. Superior air and water distribution for effective backwash giving longer filter runs and lower operating costs. The Type underdrain helps solve challenges in biologically active filtration systems, indirect and direct potable reuse applications, new drinking water applications addressing the U.
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 underdrain is compatible with all standard flume and air configurations. Easy handling – snaps together for quick installation. More driving head results in longer filter run times.

Leopold: Products – Media Filtration
Air stability is improved with all orifices providing uniform and continuous airflow. Handles for quick and easy installation, and snaps together for quick installation. 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.
