Authorised operatives

The system must only be operated and
maintained by "properly qualified opera-
tives or properly qualified technicians".
The owner is obliged:
to make an operating manual available
to the operator (supplied separately or
available upon request from your ACO
service partner), as well as these op-
erating and maintenance instructions.

System description of the separator types

The following provides a short system description and important instructions for each of the different separator types.

Filter-free light liquid separator Oleosmart (top view)
General function
In the Oleosmart light liquid separator, the
waste water containing sludge and light
liquid is divided into two flows directly af-
ter it is fed into the separator. These flow
through what is known as a coalescence
channel. Perforated sheets are installed
in the coalescence channel at right angles
to the flow direction. This generates a
turbulent flow in individual sections of the
coalescence channel, and a laminar and
straight flow in the other sections. These
different flows and the change in flow
from turbulent to laminar and straight en-
The handing over of these instructions
and manual must be recorded pursu-
ant to the mandatory stipulations. The
owner must satisfy himself that the op-
erator have read and understood these
instructions
to ensure that the system operators
have been properly instructed and can
operate the system safely

sures coalescence of the oil droplets for
the most part. These flows promote the
contact between the oil droplets. They co-
alesce with each other (self-coalescence).
In addition to this self-coalescence,
coalescence also takes place at the flow
straighteners (the perforated sheets).
These are made of an oleophile material
which supports the adhesion of the oil
droplets to the perforated sheets. After
these droplets have adhered to the per-
forated sheet, they coalesce with others
and then also float to the surface of the

water in the separator. Filters or the like,
as used in conventional separators, are
therefore no longer required in the Oleos-
mart. The light liquid collects on the sur-
face inside the coalescence channel. On
account of the surface flow, it disperses
over the entire separation compartment.
This ensures that the separator outlet is
closed in good time when the maximum
oil tank quantity is reached.
