Odis Sand Media Filters

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.
