The manual and automatic individual versions are available in the following dimensions: from Ø 500 mm to Ø 1200 mm, with flow rates from 200-400 liters/minutes to 1200-2400 liters/minutes.

Battery versions configurations from
2x, 3x, 4x, 5x, 6x, 8x with diameters that go from
Ø 500 mm to Ø 1200 mm.

These filters and the frame are completely manufactured in painted or zinc-coated steel.
In the inside lower part, Arena filters are equipped with filtering arms with 0,25 mm nozzles through which water flows outside.
 

Applications
Being this a static drop filtration system, it is suitable to any kind of filtration of waters coming from:

• canals
• lakes
• rivers

Ideal for usage in agriculture (irrigation system).

Filtration rate:
It equals a filtration rate of: 100 µ.
It assures the trapping of very small particles such as:

• algae
• organic materials
• micro-organisms
• colloids

It is advisable to mount upstream, a pre-filter such a Hydrocyclone that can remove up to 90% sand and solid particles or a screen filter.

Operation during filtration:
The example refers to an automatic single model equipped with a screen pre-filter for the back washing (enter)

Back-washing:
Over time filtration becomes less efficient and flow rate loss in outlet may occur (or loss of load) (enter)

Maintenance:
If properly used and dimensioned, maintenance is basically null.
The forced back-washing system clan and re-generates the grit layer which, besides, over time, needs to be replaced.
Total grit replacement frequency depend on the filter usage conditions and on the kind of water to be filtered.

Grit replacement
We normally advice grit complete replacement every 4-5 years because over time grit tends to get round by smoothing consequently blocking the micro-holes of the filtering arms placed at the bottom (flow rate decrease).
