A media filter uses gravel (or sand) as a bed that captures the suspended matter in the water
flowing through.
Media filters are particularly effective for filtering algae, organic matter and recycled water.
Odis media filters (series 4000) use a unique design of a double bottom chamber, divided by a
welded reinforced steel plate.
The upper chamber contains the gravel (or sand) media, the lower chamber is empty and
collects the filtered water.
The plate is covered by “mushroom” diffusers which are plastic, slotted conical units. They
disperse the water uniformly, using effectively the whole media volume avoiding the occurrence
of channeling or caking when operated correctly. This filter is particularly suitable for
backflushing – a process involving the reversal of the water flow, causing a turbulent expansion
of the media as a fluidised bed.
This flushes out the entrapped debris effectively.
After the backflushing is completed, the filter resumes its normal filtering mode as clean as a
new filter.
The backflushing process can be activated manually or automatically by controller or computer.
