Sludge Collector Underdrain System


Detail
- Filter Underdrain Block System
- Imported from the United States of America (USA), established in 1924.
- Designed to increase filtration capacity and efficiency for both filter rehabilitation and new construction projects.
- High backwash efficiency, significantly extending the lifespan of the filter media.
- Combined air and water backwash design, providing superior cleaning performance compared to water-only backwashing.
- Leopold's Dual Parallel technology ensures uniform water and air distribution while eliminating dead zones.
- Features an extra-long internal design that extends filter runs, increases water filtration volume, and reduces backwash wastewater volume—resulting in lower water production costs.
- Easy to install, lightweight, and requires minimal installation time.
- Certified to the ANSI/NSF 61 standard.
- SST has successfully installed this system in over 75 projects since 2009.
