Bag Filters – Industrial Liquid Filtration & Particle Removal Solutions

Headquartered in Delta, BC-within the Vancouver metropolitan area-Pureworld Solutions supports industrial clients throughout Western Canada with comprehensive bag filter systems and liquid filtration technologies for effective particle removal across diverse industrial applications.

Pureworld Solutions Inc.’s Expertise in Bag filters

At Pureworld Solutions Inc., we specialize in delivering high-performance bag filters and filter bag housings that provide reliable particle removal and liquid clarification for industrial process and wastewater applications. Our bag filter solutions range from single-bag vessels for low-flow applications to multi-bag systems handling thousands of gallons per minute. By partnering with multiple leading manufacturers, Pureworld Solutions Inc. provides unbiased equipment recommendations based solely on your specific filtration requirements—not brand preference.

How Bag filters Operate

Bag filters operate by directing liquid flow through a porous filter bag that captures suspended particles while allowing clean filtrate to pass through. Liquid enters the filter housing and flows from the outside of the bag to the inside (or inside to outside depending on design), depositing contaminants on the bag surface and within the filter media depth. As particles accumulate, differential pressure across the bag increases until reaching a predetermined threshold indicating bag replacement is needed. Filter bags are available in various materials and micron ratings to address specific contaminant types and particle size distribution requirements.

Benefits of Bag filters

• Cost-effective filtration with low initial investment compared to alternative technologies
• Simple operation with easy bag changeout requiring no special tools
• Wide range of micron ratings from 1 to 800 microns for versatile applications
• High dirt-holding capacity reduces changeout frequency and operating costs
• Multiple filter media options including polypropylene, polyester, nylon, and specialty materials
• Nominal and absolute-rated bags available for specific filtration requirements
• Low pressure drop for energy-efficient operation
• Compact footprint suitable for space-constrained installations

Frequently Asked Questions About Bag filters

What filter bag materials does Pureworld Solutions Inc. provide?

Pureworld Solutions Inc. provides filter bags in a comprehensive range of materials including polypropylene, polyester, nylon, Nomex, PTFE, stainless steel mesh, and specialty materials for specific chemical compatibility requirements. We help select optimal bag materials based on your fluid chemistry, temperature, and filtration efficiency requirements.

What is the difference between nominal and absolute-rated bag filters?

Nominal-rated bag filters capture a stated percentage (typically 50-90%) of particles at the specified micron rating, while absolute-rated bags capture 99.9% or greater of particles at the rated size. Absolute-rated bags cost more but provide guaranteed particle removal for critical applications. Pureworld Solutions Inc. helps determine which rating type best suits your specific application requirements.

How do I know when to change filter bags?

Filter bags should be changed when differential pressure across the housing reaches the manufacturer’s recommended maximum (typically 15-25 psi), when flow rate drops below acceptable levels, or at scheduled intervals based on operating experience. Installing a differential pressure gauge on the housing provides reliable indication of bag condition. Pureworld Solutions Inc. can help establish optimal changeout schedules for your application.

What size bag filter housing do I need?

Bag filter housing size depends on flow rate requirements, available pressure drop, contaminant loading, and desired service life between changeouts. Standard sizes include #1 (7″ x 16″), #2 (7″ x 32″), #3 (4″ x 8″), and #4 (4″ x 14″). Pureworld Solutions Inc. provides sizing assistance to ensure optimal performance and cost-effectiveness for your specific application.
