WORKING STAGES

Level 0 machine operator (User)
Level 1 Machine operator (Client technician)
This chapter briefly describes the various stages involved in a working cycle.
The stages in a working cycle may vary according to the type of processing and the product to be
processed.
The main difference lies in the quantity of solids present in the product to be filtered. Whenever
musts, lees or high suspended solid products are processed, the OMNIA filter uses both its rotating
screener to remove these solids and the rotating brush for the removal of the fibre.
Whenever wine or other products without suspended solids are filtered, the rotating screener can
be excluded from operation, and only the rotating brush is used to remove the fibre deposited on
the membranes.
The stages in a working cycle are:

- Filling,

- Pressurization (only for the filtration of spumante)
- Filtration,
- Filtration of the concentrate (except during lees filtration)
- Emptying of the product
- pressure venting
- Washing
All filtering cycle operations are performed automatically.
In some cases, however, the operator may have to stop the cycle currently underway to manually
start a new stage or to start the same stage again from the beginning or from where the cycle was
interrupted.
9.1 FILLING
The OMNIA system is filled through a dedicated inlet coupling A3 after suction by the mono pump
PPM.
The liquid potentially dilled with separable solids enters the rotating screener SRB and permeates
through a grating kept clean by a rotating brush.
The liquid then flows out through the valve 208 in order to enter the cross-flow filter vessel(s) for
filtration.
