Hydrok GTR Screen

Rotary Drum Screw Screen

GTR screens with or without compactor are used for solid liquid separation for high flow rate and combine two operations:
filtration and compaction. They feature a screen basket, this may be either perforated plate or wedge wire and acts as a filter.

The screen basket rotates with the transport screw to pass the screening debris into a transport section that ends with a
compacting/dewatering module, provided with a chute or a bagging system. A shafted screw conveys the screenings to the
compacting/dewatering section where both the volume and the weight are reduced (up to 40%).

The machine is usually installed inside a channel of suitable width, however may also be supplied installed within a Hydrok
package receiving tank.

The standard GTR rotary drum screen is supplied with one single gear motor to provide the drive to the screw and to the
drum, Alternatively, the GTR‐D can be supplied with two independent motors, one motor to drive the screw and a second
motor to drive the drum. The dual motor solution is recommended in the case of high solids presence in the effluent to
screen, this leaves the drum totally independent with no obstructions which could represent a problem for the free passage
of the screenings.
