Filter Gravel, Garnet, Greensand Plus, and Well Pack Solutions

SR Carbon offers a complete range of support media and specialty filtration materials for industrial, municipal, and residential water treatment systems. Each media is designed to work as part of a multi-layer filtration process to ensure maximum efficiency, durability, and purity.

Filter Media Solutions

Premium Filter Media

🔹 Filter Gravel

Acts as a support bed in multi-media filters.

Ensures proper flow distribution and prevents fine media from escaping.

Available in multiple sizes for graded support layers.

✅ Applications: Drinking water plants, wastewater treatment, industrial filters.

🔹 Garnet

A high-density, hard mineral used as the bottom layer in multimedia filters.

Provides superior filtration of fine particles and prevents media migration.

Mohs hardness: 7.5 – 8.0 (very durable).

✅ Applications: Wastewater polishing, desalination plants, high-pressure filtration.

Specialized Solutions

🔹 Greensand Plus

Coated with manganese dioxide for iron, manganese, and hydrogen sulfide removal.

Works through oxidation and filtration.

Can be regenerated with potassium permanganate (KMnO₄) for long service life.

✅ Applications: Groundwater treatment, municipal water supply, borewell water systems.

🔹 Well Pack Solutions (Silica Sand / Gravel)

Specially processed high-purity silica sand and gravel used for well packing.

Ensures stability, uniform particle size distribution, and chemical resistance.

Prevents fine migration and supports high yield from wells.

✅ Applications: Tube well construction, borewell development, groundwater filtration.
