EFD – ROTARY DRUM STRAINER
The EFD – ROTARY DRUM STRAINER the ideal machine for the separation of suspended particles present in waste water.


The slurry to be treated, entering the tank through the entrance and are distributed over the entire length of the drum. The slow rotation of the drum separates the material in suspension in the water and is transported in front of the machine and discharged by a scraper.
While the waste remain in the external part of the drum water it is filtered by the sieve and passes through the drum and is collected in a tank, positioned below the machine
The drum is kept clean by the double passage of water and by high pressure wash and consists of perforated networks in wedge wire profiles and two side closures and inspected made of stainless steel.

The EFD can be manufactured in Stainless Steel AISI304-316 (L), and is fully customizable according to the customer needs, but anyways we offer a standard range which can help the costumer in his final choose:

IFD – INTERNAL DRUM STRAINER
The IFD – INTERNAL DRUM STRAINER is a machine for waste water treatment with interchangeable filtration basket.


The body is made are composed in stainless steel sheet and the internal baskets are maked in holed sheet
(circular holes from 2 to 6mm) or in trapezoidal profile Wedge Wire stainless steel net (spacing 0.25mm –
2mm) that filters the water retaining, in the drum , the solid waste .
The wastewater once they enter into the machine , access inside the rotating basket and filtered. A plate welded to helix within the basket conveys thanks to the slow rotation of the resulting materials towards the discharge mouth.
The internal or external cleaning system , high pressure water sprays and removes all types of stuck
material on the surface of the filter screen .
This system can be activated manually, or programmed to operate at need.

GTR – ROTRARY DRUM SCREEN
The GTR – ROTARY DRUM SCREEN with or without compactor are machines usable for solid/liquid separation in case of big water flowrate.


This machine is composed by a screen basket in holed sheet (circular holes from 2 to 6mm) or in trapezoidal profile Wedge Wire stainless steel net (spacing 0.25mm – 2mm) which filter the waters holding back the solid particles.
This sieve, rotates together with the transport screw, placed in the cochlea, and move the resulting materials up to the compaction and dehydration zone where they’ll be discharged allowing a reduction of volume and weight of that waste by over 40%.
The machine can be installed inclined (between 35 ° and 45 ° depending on the needs) into a concrete
channel or in a stainless steel tank to receive the waste waters from a fix pipe; this version is called GTR-T – ROTARY DRUM SCREEEN IN TANK.
The GTR – ROTARY DRUM SCREEN is supplied with a single gear motor which move the screw and the sieve
together, but it can be equipped with two separate gear motors (one for the screw rotation and one for the sieve rotation); this version is called GTR-D – DUAL ROTARY DRUM SCREEEN.
This version is particularly recommended when, into the waste water is present a large amount of solid
waste to be filtered. The double motorization guarantees the independence of the two rotary elements of the machine (screw and sieve) and consequently a greater reliability and sturdiness of the entire system.

DFH – DISK FILTER
The DFH – DISK FILTER is one of the most technologically advanced filtration solutions on the market and is the latest step in a modern system of waste water filtration.

Every disc is composed by eight plastic looms with 20 micron filtering frame in stainless steel, and every loom is fixed at the central octagonal pipe.
The wastewater, once entered, fall into the discs by gravity and filtered by the frame.
The filtered water is collected in the stainless steel tank.
In a first moment the disks are in rest position (immobile) until their filter is occluded causing a water level increase into the disks and in the pipe.
This water level increase is detected by a sensor which activate the gear motor and therefore the disks
rotation.
This rotation, together with the high pressure washing, cleans the frame by the materials which fall down into inclined discharge hopper which transfers the material to the outside thanks the dedicated outlet.


The DFH can be manufactured in Stainless Steel AISI304-316 (L), and are fully customizable according to the customer needs.
