ODIS Series 4000 Media Filter Tanks

Sand media filter used to filter organics from open water supply suitable for drip watering to 100 micron. Odis recommends the use of secondary screen filters be installed downstream.

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 two chambers, 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.

Technical Data

• Media Filter uses gravel (or sand) for depth filtration.
• Double chamber with "mushroom" diffusers for efficient filtration and backflushing.
• Minimum media size: 0.6 mm.
• After backflushing, filter resumes its normal filtering mode as a new filter.
• Maximum working pressure: 8 bar (120 psi). Horizontal inlet/outlet,
• Models: 4121(1"), 41615(1 "), 4162(2"), 4202(2"), 4203(3"), 4242(2"), 4243(3").
• Top vertical inlet/horizontal outlet (short legs), Models: 4303A(3"), 4363A(3"), 4484A(4"), 4604A (4).
• Top vertical inlet/bottom vertical outlet (long legs),
• Models: 4363U(3"), 4484U(4"), 4604U (4).
• Rubber coated metal legs isolate the filter from the ground to prevent corrosion and damage to the protective coating.
• Large service openings for inspection and service.
• Modular design particularly suitable for flexibility in assembly of arrays for various flow rates
