Before the plant can be operated, the tank
(5) must be filled with water until it over-
flows into the outlet pipe (4). The waste
water to be treated flows freely through
the inlet line (9) as a result of the gradient
and enters the plant via the inlet submer-
sible pipe (10). The baffle plate (11) then
distributes it inside the tank (5). Because
the waste water is retained inside the
tank (5) for a period of time, the heavy
substances sink down into the sludge
trap (7) and the light substances float
up into the separator (6). Once treated,
the waste water flows through the outlet
Type -B
Remove the lid (1) of the manhole
cover.
Pump the contents through the suction
hose and into the suction vehicle.
Clean the inside of the tank (5) and the
components (3, 10 + 11) with water
and transfer any waste water gener-
ated into the suction vehicle.
Fill the tank (5) with water until it over-
flows into the outlet pipe (4).
Put the lid back on.

submersible pipe (3), into the outlet pipe
(4) and towards the sewer. Thanks to the
submersible pipes (10) + (3) at the inlet
and outlet and the way the sludge trap (7)
and separator (6) are designed, the freely
separable and settleable constituents
remain inside the tank (5). Once the plant
has reached its maximum capacity for
storing sludge and fat, the entire contents
must be emptied and disposed of. This
must happen once a month even if the
maximum level has not been reached. The
procedure for this is as follows:
Type -D
Connect the suction hose of the suction
vehicle to the coupling of the inner suc-
tion pipe (8).
Pump the contents through the in-situ
disposal line and into the suction ve-
hicle.
Remove the lid (1) of the manhole
cover.
Clean the inside of the tank (5) and the
components (3, 8, 10 + 11) with water
and transfer any waste water gener-
ated into the suction vehicle.
Fill the tank (5) with water until it over-
flows into the outlet pipe (4).
Put the lid back on; the plant is now
ready for operation again.
The grease separator plant consists of
the tank (5) and an attachment system
(2, including top section, supporting ring
and manhole cover – in accordance with
the installation depth and load class). The
separator (6) and sludge trap (7) are ar-
ranged on top of one other inside the tank
(5). From a purely physical perspective,
the plant relies on the gravity principle
(difference in density): heavy waste water
constituents sink to the bottom and light
substances such as animal oils and fats
rise to the top of the tank (5).
Optional:
A sampling device can be installed using
the attachment system (2). It can be con-
nected to the sampling device connection
(3) and then used to take a waste water
sample. Alternatively, there is a sampling
shaft available. The sampling device and
sampling shaft can be purchased as option-
al items from ACO at www.aco-tiefbau.de.
