Modern filter paper is designed with advanced materials to meet stringent filtration requirements. Key characteristics include:
High Dirt-Holding Capacity** – Captures fine particles while maintaining flow efficiency.
Chemical & Thermal Resistance** – Compatible with aggressive fluids and high-temperature processes.
Controlled Pore Size** – Available in microfiltration (1–10 µm) and ultrafiltration (<0.1 µm) grades for different purification levels.
Wet & Dry Strength** – Resists degradation in both aqueous and solvent-based environments.
Common Materials Used**
Filter paper for cartridges is made from:
Cellulose** – Cost-effective, biodegradable, and suitable for general-purpose filtration.
Glass Fiber** – High-temperature resistance, ideal for harsh chemical and industrial processes.
Synthetic Polymers (Polypropylene, PTFE, Nylon)** – Enhanced chemical compatibility and longevity in demanding applications.
Applications Across Industries
1. Water & Wastewater Treatment** – Removes sediments, bacteria, and impurities.
2. Food & Beverage – Ensures clarity and sterility in juices, beer, and edible oils.
3. Pharmaceuticals – Critical for sterile filtration in drug manufacturing.
4. Automotive & Lubricants – Protects engines by filtering fuel and oil contaminants.
5. Chemical Processing – Handles corrosive fluids with high efficiency.
