Bag Filter

Industrial Bag Filter Systems: High-Capacity Liquid and Dust Filtration Solutions

Industrial bag filter systems combine exceptional dirt-holding capacity with low operating costs, processing liquid streams from 5 GPM to 500 GPM while capturing contaminants from 1 micron to 500 micron. A single 4-inch by 20-inch polypropylene filter bag holds 8 to 15 pounds of solids before replacement, delivering 70% labor savings and 60% waste reduction versus cartridge filter banks requiring frequent element changes. Melko manufactures single bag filter housings, multi bag filter vessels with 2 to 18 bags, and duplex bag filter systems enabling uninterrupted operation during bag changes—serving water treatment plants, chemical processing facilities, food and beverage production, and industrial dust collection applications.

Liquid Filtration Bag Filter Systems and Filter Bag Materials

For liquid filtration applications, stainless steel bag filter housings handle corrosive chemicals, high-temperature process fluids, and food-grade water at pressures up to 150 PSI. Polyester filter bags remove particles from cooling water, paint booth recirculation, and hydraulic oil systems at temperatures from 5°C to 90°C. Polypropylene filter bags withstand acidic and alkaline solutions in chemical industry applications including electroplating rinse water, battery electrolyte, and caustic cleaning fluids. NMO filter bags constructed from nylon monofilament mesh excel in organic solvent filtration for paint thinners, lubricant blending, and resin processing. Available micron ratings include 1 micron filter bags for pharmaceutical water treatment, 5 micron bag filters for coolant filtration extending fluid life by 300%, and 25 to 100 micron options for general industrial clarification.

Dust Collector Bag Filters for Air Pollution Control

Dust collector bag filter systems employ pulse jet cleaning technology for cement plants, shot blasting operations, and air pollution control in boiler exhaust streams. Cage bag filters with rigid wire supports prevent fabric collapse under negative pressure in high-volume applications exceeding 10,000 CFM airflow. Venturi bag filters incorporate trumpet-shaped inlets distributing particle-laden air evenly across filter surfaces, extending bag life from 12 months to 30 plus months in abrasive dust environments. Polyester felt bags handle wood dust, grain elevator particulates, and general manufacturing emissions at temperatures below 130°C. Nomex aramid bags withstand 200°C in asphalt plants, coal-fired boilers, and incinerators. PTFE membrane bags achieve 99.99% submicron particle capture for pharmaceutical powder processing and toxic heavy metal dust control.
