Odour Treatment

Odours from industrial, agricultural, and wastewater operations can have a significant impact on air quality. Filtralite® Air filter media is specifically developed for odour control applications in air and gas purification systems, offering a reliable and efficient solution.

Porosity That Supports Biofilm Growth

Made from lightweight expanded clay, Filtralite Air has a highly porous structure that promotes biofilm development while ensuring a continuous and even flow of air through the filter bed.

This unique property makes it ideal for biofilters in odour treatment facilities, allowing larger volumes of air to be treated within the same footprint. Its high storage capacity and low pressure loss over time also contribute to reduced operational costs and long-term efficiency.

Effective From the Start

Filtralite Air filter material begins adsorbing odours, including hydrogen sulphide (H₂S), even before biofilm is fully established. This ensures effective treatment from the very beginning.

Odour treatment systems typically operate by channeling air or gas through filter media that is continuously sprinkled with water. Filtralite Air acts as a stable base for biofilm growth and ensures even airflow through the filter bed for efficient odour treatment.

Why Choose Filtralite® Air for Odour Treatment?

Stable structure - Does not collapse under pressure, ensuring consistent performance over time.
Durable and resistant - Made from natural expanded clay without any hazardous or artificial components.
Lightweight - Up to five times lighter than traditional mineral materials.
Large surface area - Good storage capacity for biofilm and excellent permeability.
Excellent permeability - Ensures uniform airflow and low pressure drop across the bed, minimizing energy use and system stress.
Water-holding capacity - The porous structure absorbs and holds water which improves the efficiency of water trickling.
Efficient odour removal - The material’s sorption capacity enables removal of odours, including H₂S, from the air even before full biofilm activation.
