Traditional Filter Media

---

Overview

We offer a complete range of traditional filter media including gravel, pebbles, sand, quartz, and anthracite. These calibrated natural materials form the foundation of multi-layer filtration beds in industrial, municipal, and commercial treatment plants. Their role is to provide depth filtration, stable hydraulic performance, and long-term protection of downstream systems.

Key Features

Traditional filter media are valued for their proven reliability and mechanical strength. Graded gravel and pebbles provide stable support layers, ensuring uniform distribution of flow and backwash water. Quartz sand offers effective turbidity and suspended solids removal with predictable head loss characteristics. Anthracite adds depth filtration capability, extending run times and improving bed performance. Sourced and processed to industry specifications, Duvera media deliver consistent quality and long service life.

Applications

These media are widely used in pressure filters, rapid sand filters, and multimedia filtration units. They are standard for pretreatment in industrial water plants, municipal waterworks, and commercial buildings. Applications include turbidity reduction, suspended solids removal, and as support beds for advanced media such as glass or activated carbon. They also play a critical role in protecting UF and RO membranes by stabilising feed water quality.

Specifications

Available in standard particle sizes and uniformity coefficients suitable for water and wastewater treatment. Gravel and pebbles are supplied in calibrated grades for support bed layering. Quartz sand is available in fine, medium, and coarse grades for primary filtration. Anthracite is provided with controlled grain sizes to improve depth filtration and reduce pressure drop. All media conform to accepted water treatment standards, ensuring compatibility with pressure vessels and filter housings of varying capacities.
