Filtering with media filters is also recognized as depth filtration.The media filters perform the filtration of water through a thick layer of graded particles.
These particles can be sand, gravel or other granular materials. The filtration rate depends on the effective size of the bedding and the water velocity through the filter. Amiad offers a complete line of manifolds, accessories and control systems for single or multiple media filters.
The Amiad Customer Support Department is at your service in designing complete media filtration systems with gravel, sand, active carbon or multi-layer beddings:
- For manual or automatic operation
- For single or multi-units, manifolded
- For complete filtration solutions
How the Sand / Media filters work:
Water enters through the filter inlet and percolates through the filter bed. When suspended matter comes in contact with media particles, it absorbs it. Clean water Then goes via the filtration nozzles through the filter outlet. Cleaning is done by backwashing.
Water is inserted in reverse direction - from the nozzles upwards, causing suspension of the filter bed, thus releasing the suspended matter from the bedding and it is flushed out through a backwash valve. Backwashing may be done automatically according to pressure differential and/or according to time.
