How Do ABFT Filters Work
GeneralAmiad ABFT Automatic Filters are first-rate solutions to protect the main process lines from heavy dirt loads and large particles. Amiad ABFT Series consists of heavy duty filters with an electric self-cleaning mechanism. The ABFT Series is available for flow rates from 110 gpm / 25 m3/h up to 25,000 gpm / 5,700 m3/h per vessel, with filtration elements ranging from 200-10,000 micron, with inlet/outlet flanges available up to 36” / DN900 diameter.
The Filtering ProcessRaw water enters the inside of patented “cross screen” cylinder from the filter’s inlet and flows through the screen to the filter’s outlet. The gradual dirt building up on the inner screen surface causes a filter cake to develop with a corresponding increase in the pressure differential across the screen. A pressure differential switch senses the pressure differential when it reaches the preset value or after a preset time has elapsed, and the cleaning process begins.
The Self-Cleaning ProcessCleaning of the filter is carried out by a brush system. The exhaust valve opens and the drive unit starts to rotate the stainless steel /nylon brushes, which sweep the inner surface of the cylindrical screen. The particles trapped on the screen are dislodged by the brushes and flushed out the exhaust valve. During the self-cleaning process, filtered water continues to flow.
The Control SystemThe control system operates with a switch that senses the pressure differential across the screen and sends a signal to the control board when it reaches a pre-defined value (usually 7 psi/0.5 bar), or when the predefined time elapsed; then, the control board initiates the self-cleaning process.
The self-cleaning cycle is initiated as a result of any of the following:• Receiving a signal from the pressure differential switch• Time interval parameter set at control board• Manual start
