Dual Media Filters

Advanced filtration using layered media (e.g. anthracite + sand) for efficient turbidity and solids removal.

UNDER CONSTRUCTION

Overview

Cube Consolidating Dual Media Filters remove suspended solids, turbidity, organic particles, and colour from process liquids using a layered granular media bed. A coarse anthracite layer over finer sand provides effective depth filtration, capturing a wide range of particle sizes for consistent water clarity.

These filters offer dependable pretreatment for downstream systems such as reverse osmosis, activated carbon, and biological treatment, extending equipment life and ensuring stable, high-quality performance across industrial and municipal operations.

Technical Highlights

Typical media bed depth: 0.6–1.6 m (total) with anthracite on top, sand underneath
Flow rates: 5–20 m/h (~3–8 gpm/ft²) in gravity filtration; pressurised systems allow higher flux rates.
Particle removal: achieves turbidity and TSS reduction consistently under 10–20 μm
Backwash trigger: pressure differential around 10 psi (~0.7 bar) typically initiates cleaning.

Key Features

Raw water flows through layered media that trap particles of varying sizes, with periodic backwashing to maintain filtration efficiency and extend run times.

Key Benefits

Cube Consolidating Dual Media Filters deliver high-efficiency particle removal with extended run times, low pressure drop, and versatile configurations for reliable, low-maintenance operation.

Industries Where Dual Media Filters Are Used

Dual Media Filters provide upstream protection and polishing across industries such as:

Potable and drinking water treatment: turbidity and iron/manganese reduction
Reverse osmosis pre-treatment: increases membrane lifespan
Industrial and municipal wastewater: tertiary filtration, solids removal
Food, Beverage, and Pharmaceuticals: improved clarity and impurity removal
Mining, Chemical, Agriculture, Pulp & Paper: process water clarification and reuse preparation
