2. Features of the Filtration System.
1. Introduction.
Thank you for trusting in AZUD HELIX AUTOMATIC equipments to solve your filtration
requirements. Please read carefully this manual and you will find answer to most of your questions.
IF YOU HAVE ANY QUESTION OR NEED ADITIONAL INFORMATION; PLEASE CONTACT US IN
[phone] OR [e-mail]
All the equipments manufactured in Sistema AZUD are subject to strict quality control tests and are
manufactured under a productive process which complies with the requirements of the standard ISO
9001/2000.
Sistema AZUD is also committed with the environment, and is certified under the Environmental
Management System of the standard ISO 14001.
This manual includes instructions and warnings to a correct installation, operation
and maintenance of the Equipment.
2.1. Exclusive Use of the filtration Equipment.
Sistema AZUD filtration equipments have been designed to exclusively filter water,
according to the Operational Conditions indicated in the Technical data and the
Industrial label of the Equipment. In any case to the filtration of dangerous liquids
(understood as such the specific in the charter 2 of article 2 of Directive
67/548/CEE, of 27th of June of 1967), or liquids for food use.

2.2. Identification of the product.
In AZUD each filtration equipment is identified by an industrial label, placed in one of the main
manifolds, with the serial number. With this number the factory can always identify the equipment.
The modification or elimination of this label cancels any warranty; and impedes the
identification of the Equipment.
The industrial label indicates: manufacturer, address, model, year of manufacturing, serial
number, max. Pressure, max. Temperature and conformity with the Directive of Pressure
Equipments PED 2014/68/EU.
The label includes QR code to access the technical documentation of the product such as
technical sheets, user manual, spare parts and/or maintenance and commissioning instructions.
The filters of the equipment,
are identified with a label in
which is indicated the model,
year of manufacturing, serial
number and max pressure.
AZUD HELIX AUTOMATIC consists of a filtering element which
comprises grooved discs, that allow the retention of particles of a size
bigger than the required filtration grade. The Equipment combines the
advantages of the disc filters with those of the helical-centrifugal effects
of the helix.
AZUD grooved discs combine on-surface filtration and in-depth
filtration to achieve the maximum precision and safety in the
filtration.
The particles are retained through the channel of the discs.

2.3. Operation Description.

TECNOLOGY
The system carries out two independent phases in each
filtering unit but simultaneous in the filtration system in
precise moments. This is called FILTRATION PHASE
and BACKFLUSHING PHASE
FILTRACIÓN STAGE
Once the water comes in the
filter, the only way to follow are
the channel of discs.
The outlet manifold is the
responsible to collect the filtered
water and carry it out to the
exterior of the same.
BACKFLUSHING PHASE
The programmer of the Control Unit, closes the
contact which supplies NC solenoid charge and
which is responsible for the activation of the first
station that will carry out the backflushing. The
solenoid converts the electric signal in a
pneumatic signal responsible for the feeding of
the backflushing valve chamber and auxiliary,
communicating the filtered water outlet with the
drainage.
Through the feeding of the three-way valve
chamber, the inlet of water to the filter is closed,
communicating the interior of the filter with the
drainage manifold, starting a backflush.
The start of the backflushing process takes place when
the Control Unit activates the backflushing cycle under
one of the four possible orders: Differential of
pressure, time frequency between backflushings or
manually on the keyboard or by external signal.
In the filtration process, water is carried from the
inlet manifold through the backflushing valves, to
the interior of the filter which form the filtration
system .

A moment after the following solenoid
introduces the air in the filtered water
deposit and inside the filtering element.
This mixture of water –air provokes a
hydraulic –pneumatic force which is
used to overcome the pressure made
by the spring over the stack of discs,
generating the decompression of the
same due to the rising of the piston.
The release of discs makes possible these can freely spin due to
the tangential projection of the water coming from the feeder bars
which at the same time are used as structural support of the stack
of discs.
The correct distribution of the holes in the bars, together with the
studied design of the same, project water under pressure which
tangentially falls into the discs, generating its rotation and vibration
of the same and consequentially the complete elimination of the
retained solids through the backflushing valve. These are carried to
the outside by the drainage manifold.
Once the station has completed the backflushing process, it is
repeated sequentially until it completes the totality of stations which
form the filtration equipment.
The end of the backflushing coincides with the closure of the
drainage outlet and the opening of the inlet manifold on the last
station which forms the filtration equipment. In this way the filtration
initial conditions are re-established and also the availability of the
totality of filters to carry out the filtration function.
All that available hydraulic power is used to overcome the
pressure exerted by the spring on the discs stack generating in
this way its own decompression due to the piston displacement
(raising).

7. Maintenance Instructions.
Maintenance Plan of the Equipment.The period between revisions depends on the operation
conditions, characteristics of water to be filtered, operation hours, number of backflushings, recuperation
of the differential pressure after the backflushings…. AZUD recommends three months between the
different revisions of components which imply the disassembly of the filtering element. This period
should be determined by the user according to the particular characteristics of his installation.
-Be sure the Equipment is depressurized before making any operation which
expose in contact the interior of the equipment with the atmosphere.
-The maintenance labours should be made by qualified staff.
For the identification of the components check section 2.5 of the manual
DAILY ACTIONS
1. Visual inspection of the Equipment
2. Checking there are not leakages in the Equipment
