What Are Filter Bags?
Filter bags, also known as filtration bags, are porous containers made from materials like polypropylene, nylon, or polyester. They are designed to capture suspended solids, sediments, and particles from liquids while allowing clean fluid to pass through. Installed within bag filter Vessels, they serve as the primary medium in liquid filtration systems.
Key Features:
Micron ratings: Available in 1, 5, 10, 25, and 100 micron sizes to target specific particle sizes.
High dirt-holding capacity: Ideal for large-volume applications like bag filters for water.
Chemical and temperature resistance: Suitable for harsh industrial environments.
How Filter Bags Work
Liquid flows through the filter bag inside a bag filter housing, where particles larger than the bag’s micron rating are trapped. Clean fluid exits the system, while contaminants remain in the bag. For example:
A 1 micron bag filter removes fine particles in pharmaceutical processes.
A 100 micron bag filter captures coarse sediments in industrial wastewater.
Periodic replacement or cleaning ensures consistent performance.
Advantages of Filter Bags in Liquid Filtration
High Flow Rates: Process up to 2,400 gallons per minute, perfect for bag filters for water.
Cost-Effective: Lower operational costs compared to cartridges or membranes.
Versatility: Compatible with diverse fluids, including corrosive chemicals and high-temperature liquids.
Easy Maintenance: Replaceable bags reduce downtime.
