When working with industrial-grade filtration, you have several options for which type of filter best meets your needs. It’s essential to understand both filters’ benefits before choosing the right filtration technology for your performance demands. Both filter types are sediment filters that remove large and small debris from various types of liquids through different processes. The type of filter you choose is also dependent upon the size of the micron size and flow capacity needed. The smaller the particles and bacteria are that need to be filtered, the more opportunity there is for buildup to clog the filter.

Bag Filters
Bag filters offer a wide range of filtration media depending upon the application. Activated carbon, needle felt, and nylon monofilament mesh are among the most common. Waste solids are trapped inside the bag producing less solid waste than when using a cartridge filter, reducing disposal costs, and have a low rate of clogging. Bag filters are one of the lowest-cost types of industrial filtration tools, making them optimal for small-batch systems typically used in mining, chemical, food, and beverage production. Bag filters have a smaller surface area in comparison to cartridge filters. Small, permeable pores capture debris and sediment as the liquid passes through using microfiltration for purification. The micron size of the pores affects the size of the contaminants a bag filter can remove.

Cartridge Filters
Cartridge filters utilize high-capacity pleated media or a screen to capture solid contaminants. They are best used for filtration at beverage, food production, pharmaceutical, chemical, and paint plants where sub-micron filtration is required to remove acids and bases when ultra-pure water filtration is needed. The two most commonly used types of cartridge filters are surface and depth filters. Surface cartridge filters retain particles on the media’s surface, forming a layer of material which in turn increases productivity. The use of a thick or multi-layered media in a depth cartridge filter traps debris via the formation of a twisted path. Cartridge filters are more universally adaptable to most industries, including cosmetics, pharmaceuticals, and electric utilities. They are low maintenance and allow for ultra-pure water filtration needed for small micron filtration.
