In industrial filtration systems, the proper use and maintenance of disc filter bags directly affect filtration performance and equipment efficiency. Based on years of application experience, Bolian has developed a comprehensive maintenance and troubleshooting guide to help users extend the service life of filter bags and reduce operating costs.
When installing disc filter bags, it is essential to ensure that the filter bag fits tightly against the filter disc and that the sealing ring is positioned correctly. Improper installation may cause leakage, reduced filtration precision, or decreased efficiency. Before installation, always check that the filter bag is intact and undamaged; after installation, verify the sealing to guarantee system stability and performance.
During operation, users may encounter problems such as bag clogging, damage, or leakage.
Clogging often occurs when the solid content in the filtrate is too high or when cleaning is not performed regularly. This can be alleviated by adding a pre-filtration step or increasing the cleaning frequency.
Damage or leakage is usually related to bag aging, improper installation, or excessive pressure difference across the filter. In such cases, timely replacement and system inspection are necessary to restore optimal
performance.
Regular cleaning and proper maintenance are crucial to prolonging the service life of disc filter bags. Bolian recommends using clean water or a neutral detergent for washing. Avoid strong acids or alkalis, which may damage the fiber structure. After cleaning, the filter bags should be thoroughly dried to prevent bacterial growth or material degradation. Typically, the need for replacement can be determined by observing pressure changes, reduced flow rate, or decreased filtrate clarity.
Disc filter bags should be stored in a dry, ventilated, and shaded environment, away from high temperatures and humidity. Keeping the filter bags in their original packaging helps prevent contamination from dust, oil, or other pollutants, maintaining their cleanliness and stability for future use.
Bolian promotes green manufacturing and sustainable waste management. Used filter bags should be sorted and disposed of according to material type, with recyclable components processed appropriately to reduce environmental impact. Users are encouraged to comply with local environmental regulations when handling discarded filter bags.
By following proper installation procedures, regular cleaning schedules, and reasonable replacement intervals, Bolian disc filter bags can maintain long-term, high-efficiency filtration performance, ensuring stable, safe, and energy-efficient operation across industrial applications.
