Liquid Filter Bag
A liquid filtration system consists of two main parts:
This is the core consumable element, typically made from non-woven or woven materials like polypropylene, polyester, or nylon. The bag features a metal or plastic ring at the opening for a secure and leak-proof seal within the housing.
Key Components and How It Works
A liquid filtration system consists of two main parts:
The Filter Bag
This is the core consumable element, typically made from non-woven or woven materials like polypropylene, polyester, or nylon. The bag features a metal or plastic ring at the opening for a secure and leak-proof seal within the housing.
The Filter Housing (or Vessel)
This is a durable, often stainless-steel pressure container that holds the bag. Inside, a supportive mesh basket (called a filter basket) cradles the bag, providing structural integrity against fluid pressure.
The Process
The process is straightforward:
- The unfiltered liquid enters the filter housing, flowing around the outside of the filter bag.
- Under pressure, the liquid is forced through the porous media of the bag wall.
- Solid particles larger than the bag’s pore size are trapped on the bag’s surface or within its depth.
- The clean, filtered liquid passes into the interior of the bag and exits the housing through the outlet.
When the bag becomes saturated with contaminants, indicated by a pressure drop, it is easily replaced, minimizing downtime.
Main Advantages of Using Liquid Filter Bags
- High Filtration Efficiency: They offer a wide range of filtration ratings, from 1 to 800 microns, for both coarse and fine filtration.
- Large Dirt-Holding Capacity: The depth filtration technology allows them to retain a significant amount of solids before needing replacement.
- Cost-Effective: As disposable elements, filter bags are economical and quick to change, saving on labor and maintenance time.
- Versatility: Available in various materials to handle different chemical properties, temperatures, and viscosities.
- No Media Migration: High-quality bags are designed to prevent fibers from shedding into the filtrate, ensuring no secondary contamination.
Common Applications Across Industries
Liquid filter bags are indispensable in numerous sectors, including:
- Food & Beverage: Filtering water, edible oils, syrups, beers, and juices.
- Chemicals: Purifying resins, solvents, paints, inks, acids, and alkalis.
- Plating & Metalworking: Cleaning electroplating solutions, phosphating baths, and industrial coolants.
- Petrochemicals: Recycling and clarifying lubricating oils, fuel oils, and quench oils.
- Pharmaceuticals: Filtering process water and drug precursors under strict hygiene standards.
- Paints & Coatings: Removing skins and agglomerates to ensure a perfect finish.
The Heart of the Bag: Filter Media Materials
The performance of a filter bag is determined by its core material. The most common types include:
Polypropylene (PP)
Excellent chemical resistance, especially to acids and alkalis. A cost-effective choice for many applications.
Polyester (PET)
Offers high tensile strength and good temperature resistance, ideal for oil-based liquids.
Nylon
Known for its exceptional abrasion resistance.
PTFE (Teflon)
Provides ultimate chemical resistance for the most aggressive solvents and high-temperature fluids.
Understanding the liquid’s properties is crucial for selecting the right filter media for optimal performance and cost-efficiency.
