Application Scope of Bag Filters

Bag Filtration Principle
Bag filtration is a new type of filtration system. Inside the filter, a metal mesh basket supports the filter bag. Liquid flows in from the inlet, passes through the filter bag, and exits through the outlet, while impurities are trapped within the filter bag. The system can continue to operate after replacing the filter bag.

Trend of Bag Filters Partially Replacing Cartridge Filters
Bag filtration systems are increasingly replacing cartridge filters due to their large processing capacity, compact size, and high dirt-holding capacity. For example, a single #2 filter bag has an effective filtration area equivalent to 20 pieces of 10-inch filter cartridges. From both cost and efficiency perspectives, filter bags outperform filter cartridges.

Advantages of Bag Filtration Systems
Based on the working principle and structure of bag filtration systems, replacing filter bags is quick and convenient. Additionally, the filter requires no cleaning, saving time and labor. The likelihood of side leakage in filter bags is minimal, ensuring high filtration quality. In contrast, the side leakage probability for filter cartridges is much higher, with n cartridges having a side leakage probability of 2n! Bag filters can withstand higher working pressures, have lower pressure losses, and reduce operating costs, offering excellent energy-saving benefits. The filtration accuracy of filter bags continues to improve, now reaching 0.5 microns, making them suitable to replace cartridge filters in many applications. Bag filters are versatile, flexible, and can be installed in various configurations. They can also be used in conjunction with self-cleaning systems, membrane filtration, or other filtration systems to meet diverse needs.

Wide Application Scope
Bag filters are widely used in industries such as pharmaceuticals, food and beverage, chemicals, electronics, and water treatment. Their adaptability and efficiency make them an ideal choice for various filtration requirements.
