Filter Technology & Automatic Cleaning

A bag filter uses a filter bag to retain suspended particles and is commonly used for general industrial liquid filtration.
A cartridge filter uses one or multiple filter cartridges and is generally selected when finer or more controlled particle removal is required. Cartridge filters can also be used as pretreatment or security filtration before downstream membrane processes.

A self-cleaning filter is suitable for applications where contaminants continuously accumulate and frequent manual cleaning would interrupt production.
Depending on the application, brush, scraper, suction, or backwash cleaning technologies can be selected to remove accumulated contaminants and reduce manual maintenance.

Depending on the equipment design, automatic cleaning can be initiated by differential pressure, preset time intervals, or automatic control logic.
For example, automatic brush self-cleaning filters can use differential-pressure and timer-based cleaning to remove and discharge accumulated contaminants automatically.

Certain self-cleaning filter configurations are designed to maintain downstream flow during cleaning. For example, automatic brush self-cleaning filters can perform cleaning and blowdown without interrupting the main filtration flow.
Actual operation depends on the selected filter configuration.
