Cartage Filter and Bag Filters
these filters are used in dust and dirt collection systems.
Both cartridge filters and bag filters are widely used for liquid filtration to remove suspended particles, dirt, and impurities. They are essential in food processing, pharma, chemical, water treatment, and beverage industries.
1) Cartridge Filter
🔹 What is a Cartridge Filter?
A cartridge filter uses a replaceable cylindrical filter element (cartridge) to remove fine particles from liquids.
🧩 Main Components
Filter housing (SS/MS)
Cartridge element (PP, pleated, membrane)
Inlet & outlet connections
Support core
Sealing (O-rings/gaskets)
Working Principle
Liquid enters the filter housing
Passes through cartridge media
Impurities are trapped inside/outer surface
Clean liquid exits
👉 Works on surface or depth filtration
Applications
Water purification
🍛 Beverage & juice filtration
💊 Pharmaceutical liquids
🧪 Chemical solutions
Key Features
High filtration accuracy
Compact design
Easy cartridge replacement
Advantages
Removes very fine particles
Hygienic (food/pharma grade)
Consistent filtration
What is a Bag Filter?
2) Bag Filter
A bag filter uses a fabric filter bag inside a housing to remove medium to large particles from liquids.
🧩 Main Components
Filter housing
Filter bag (fabric/mesh)
Basket support
Inlet & outlet
Cover with sealing
Working Principle
Liquid enters the housing
Passes through filter bag
Particles are trapped inside the bag
Clean liquid exits
Works on depth filtration
Applications
Chemical industry
🏭 Industrial water filtration
🛢️ Oil filtration
🍛 Food processing (coarse filtration)
Features
Handles high flow rates
Large dirt holding capacity
Easy to clean/replace
Advantages
Cost-effective
Suitable for high contamination
Simple design
Where They Are Used Together
👉 In many plants:
Step 1: Bag Filter → removes large particles
Step 2: Cartridge Filter → fine filtration
👉 This improves efficiency and reduces cost
Example – Food Processing Setup
Raw liquid → Bag Filter → Cartridge Filter → Storage Tank → Packing
👉 Ensures:
Clear product
High quality
Longer shelf life
