Water Treatment · Media Filters
Pebbles
Overview
Natural, durable, and chemically inert supporting media used in water and wastewater filtration systems. Sourced from riverbeds, these smooth, well-rounded pebbles form the foundational layer beneath sand, anthracite and activated carbon filters — preventing finer media loss and supporting underdrain systems in both gravity and pressure filtration.
Applications
- Potable water treatment facilities
- Industrial processes requiring high-purity water
- Swimming pool filtration systems
- Wastewater treatment operations
- Well and sump protection against sediment intrusion
