GENERAL DESCRIPTION
The SOMAT® system prepares solid waste materials for disposal by transforming the
materials, with water, into a pulp. This transformation takes place in a unit called a Pulper
which is designed to pulp all forms of paper, plastic, cardboard and food waste. The waste
material is fed manually or automatically to the Pulper. The continual down flow of water
and the rotation of the Pulper impeller create a strong vortex action which pulls the waste
down against the cutting blades of the impeller. The resultant slurry is then forced through
a perforated stainless-steel Sizing Ring surrounding the impeller.

9
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.
TYPICAL HYDRA-EXTRACTOR®

10
DEFINITIONS – GENERAL
Pulper - device that contains an impeller and sizing ring to grind solid waste. The
resultant mixture of waste particles and water is called slurry.
1. Hydra-Extractor® - Inclined screw-type press for removing transport water from pulp.
2. Slurry - A water solution containing a low percentage of suspended solids.
3. Pulp - Semi-dry solid from which transport water has been extracted.
4. Som-A-Trol® - Electrical control panel, including motor starters and sequencing
controls for automatic operation of the SOMAT® system.
5. Slurry Pump - Specially designed pump used to transport slurry from a SOMAT®
Pulper to Hydra-Extractor®.
6. Return Pump - Specially designed pump used to return water from Hydra-Extractor®
to SOMAT® Pulpers.
7. Water Level Control - a PLC controlled function utilizing time-based programming.
8. Chemical Additive Pump - A proportioning type Additive pump that adds de-foaming,
deodorizer, and/or buffering solutions to the process water.

11
DEFINITIONS –COMPONENTS
SOMATPULPER:
1. Tank - Pulping or grinding chamber of the SOMATPulper.
2. Impeller - Rotating metal plate with Tungsten Carbide Blades which de-fiber and
pulp the waste and along with the Security Ring provides a shearing action for
non-fibrous waste.
3. Security Ring - Perforated stainless-steel ring surrounding the impeller through
all slurry must pass after waste is pulped. Dimensions of security ring holes
controls particle size of materials leaving the Pulper.
4. Junk Box - Chamber in bottom of tank that segregates non-pulpable materials
from tank.
HYDRA-EXTRACTOR:
1. Screw - Vertical helix which lifts and compresses solids from the slurry and
permits water to drain off by gravity.
2. Screen - Mesh screen that surrounds the screw, through which water drains off.
3. Plug - Mass of pulp extending beyond last helix of the screw. The force required
to extrude the plug squeezes additional water from pulp.
4. Brush - Nylon brush attached to edge of screw helix which serves to clean the
screen.
5. Plug Cutter –Assists in breaking apart waste to discharge down the chute
GENERAL:
1. Throttling Valve - Full ported gate valve used to control water flow.
2. Timer - Electrical device used to automatically shut down the SOMATSystem at
a pre-determined time.
3. Fresh Water Solenoid - Electric valve used to control freshwater make-up to the
SOMATSystem.
4. Motor Operated Valve - (MOV) Electric valve used to drain water from tank and
lines for daily maintenance.
5. PLC- Computer controller designed to handle pulper and extractor operation.
