The SOMAT® System is
designed to pump the
mixture of macerated solids
and water, called slurry, to
the Hydra-Extractor® where
the slurry is reduced to a
semi-dry pulp. Within the
Hydra-Extractor®, the slurry
is carried by a helicoid
screw within a perforated
tubular screen. The water
passes through the screen
and is pumped back to the
pulping unit. The solids
continue up the helicoid
screw to a compression
chamber or plug area where
additional water is removed
by extrusion. The solids in
this area are called the plug.
This plug is broken up at the
Hydra-Extractor® discharge
opening by a cutter and the
pulp then falls out of the discharge chute
.
This system can reduce the volume of average non-compacted waste by approximately 80
percent.
The system is powered by electric motors with the associated controls housed in Som-A-Trol
(electric control panels). Since, in the course of operation, some water is absorbed by the pulp,
fresh make-up water is supplied to the Pulper automatically through a solenoid valve.
In addition to the basic system as discussed to this point, numerous additional items of
equipment may or may not be required to comprise a specific system.
