Bag filters and cartridge filters differ significantly. Bag filters, classified as single-bag or multi-bag based on flow rate, are innovative, compact, and versatile filtration devices with a metal mesh basket supporting filter bags. Liquid enters through the inlet, flows through the bags, and exits the outlet, capturing impurities. Maintenance involves replacing filter bags.
Bag filters have a compact structure, easy installation, and high filtration precision, suitable for fine particles. The filtration range is 0.5 to 200 microns, and one liquid filter bag equals 5-10 times a cartridge filter, resulting in cost reduction. Design flow rates range from 1 to 500 m3/h.
Cartridge filters are a multifunctional type used in various industries for liquid purification and solid-liquid separation. If used before reverse osmosis, they act as safety filters with 5-micron precision. After reverse osmosis, they become microfiltration membrane filters with precision below 1 micron, removing bacteria and impurities after UV sterilization. Cartridge filters include wound wire, folded, and melt-blown types, with melt-blown filters cost-effective for water treatment and easy replacement if clogged.
