SERIES 400 – disc filters

 

 

azud disc filter series 400Automatic in-line Self  Cleaning equipment with disc filter elements using 4″ valves .  Each valve controls a group of three filter elements combined on a manifold.  all the manifolds are manufactured in High Density Polyethylene.   Easy to install.   Maximum resistance and durability.   Max flow 5070 gpm).

Modular configuration allows design according to customer preference or space availability.

Automation available in 110 V, There are special options available for Low Pressure, High Pressure and Sea/Saline water conditions. Also possible to backwash with compressed air, minimizing the water loss during backwash (Air Assist Option – AA).

 

 

 

ADVANTAGES


FILTERS ALL KINDS OF PARTICLES

Organic , in-organic, and fibrous

FILTRATION AND BACKWASH OCCUR SIMULTANIOUSLY
Only a portion of the water is used for backwash in multi element systems.

LARGE FILTRATION SURFACE AREA

DISC DESIGN
The discs are available in Multi-Groove (MG) or Wall type depending on the application they are needed for. The MG discs provide depth filtration resulting in very high efficiency at a given micron level.
The width and support structure of the discs provided high resistance to the pressure differential across the filtration surface.
The superior quality of the injection molding of the discs provides uniformity of the discs which results in high efficiency at the selected micron level.

HELIX SYSTEM
The Helix is a centrifugal action device on the inlet to the filtering element which forces the inlet water to spin around the discs inside the filter housing, this forces the larger particles away from the discs reducing the accumulation of solids on the filtration surface, thus optimizing the performance of the discs and reducing the frequency of backwashing

AIR ASSIST
AA backwashing option available on all models.

MODULAR, VERSATILE, COMPATABLE
The system permits a wide range of configurations with a minimal number of components. Vertical or horizontal design.

AUTOMATIC CLEANING OF FILTER ELEMENTS
Filtration Stage: The Helix generates a centrifugal helical effect upon entry into the filter, this moves the particles away from the discs. The water then passes efficiently through the depth of the uniquely designed discs.
Backwashing Stage: The clean water from the down stream side of the filter elements is introduced from the reverse direction through the backwashing filtering element. This hydraulically decompresses the stack of discs, allowing the discs to separate and backwash efficiently.
The solids are expelled from the discs and evacuated through the backwash manifold.
The filtration process then restarts with the compression of the discs.
The backwash is controlled by two valves and a controller, which integrate the
filtration equipment. The backwash is initiated by pressure differential or time.

LOW MAINTENANCE
No tools required. Very few warring parts

MANUFACTURED IN PLASTIC
The patented design and the materials used in manufacturing the filters guarantee a long life with high resistance.
The maximum operating pressure and temperature of the standard equipment is 145 psi at 140⁰F.

WATER AND ENERGY SAVINGS
Amount of water used during backwashing cycle is significantly less than with other types of automatic cleaning filters. Time between backwashing cycles is increased by the design of the Helix system.

QUALITY CONTROL
All products go through stringent quality control before leaving the factory.

FACILITATES EASY TRANSPORTATION AND INSTALLATION
Equipment is shipped pre-assembled (Only limited assembly requird on site)

 

ADDITIONAL INFORMATION


Backwashes only one station at a time. The remaining stations stay in filtration mode and continue to supply clean water to the process
