Oleopator-C-Ost - ACO Oleosmart-C-OST Instructions De Service Et De Maintenance

General description
In the Oleosmart PR-C-NST light liquid
separator, the waste water containing
light liquid is divided into three flows
directly after it is fed into the separator.
These flow through what is known as a
coalescence channel. Where necessary,
perforated sheets are mounted in the co-
alescence channel as flow straighteners
(depending on type 0; 1 or 3) at right ang-
les 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-
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).

Operating and maintenance instructions
In addition to this self-coalescence,
coalescence also takes place at the flow
straighteners (the perforated sheets) and/
or in the coalescence pipe above the out-
let. These are made of an oleophile mate-
rial which supports the adhesion of the oil
droplets to the perforated sheets. After
the droplets have adhered to the perfora-
ted sheet, they coalesce with others and
then also float to the surface of the water.
Filters or the like, as used in conventional
separators, are therefore no longer requi-
red in the Oleosmart-PR-C-NST. An additio-
nal removable coalescence element (coa-
lescence pipe) is mounted above the drain
pipe. 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

General description of the Oleopa-
tor-C-OST light liquid separators
Oleopator-C-OST light liquid separators
have an integrated sludge trap (5). This
allows sediments and light liquids to be
separated out simultaneously in one tank.
This means that an additional sludge
trap positioned upstream of the light
liquid separator is no longer required.The
Oleopator-C-OST light liquid separator has
an optimised sludge trap. The Oleopator-
C-OST light liquid separator is therefore
particularly compact.
closed in good time when the maximum
oil tank quantity is reached.
Coalescence channel
The guide walls of the coalescence
channel in the Oleosmart-PR-C-NST are
made of an oleophile material, as are the
perforated sheets, which serve as flow
straighteners or turbulence generators,
depending on the layout. The oleophile
material supports the coalescence of the
smallest oil droplets.
After the light liquid has been separated
from the waste water, the light liquid coll-
ects on the surface of the water.
General function of the Class I
light liquid separators
Light liquids in the Oleopator-C-OST light
liquid separators are separated out by a
coalescence unit which helps trap the fin-
est oil drops and coalesce them together
to form larger oil drops capable of being
separated out. This coalescence unit (2)
consists of a cylindrical coalescence ele-
ment centrically positioned around the
float cage. It consists of a PE-HD sup-
porting basket and usually a single or
double-layered coalescence mat made out
of a mixture of knitted materials (stainless
steel and polypropylene or polyurethane
material (only from Oleopateor NS 40)
which is wrapped around the supporting
basket and held in position by
tensioners with Velcro strips. In the NS
6 version (only Oleopator) with a 1800-,
2500- or 5000-litre sludge trap, the co-
alescence element consists of a cylindri-
cal, PE-HD perforated sheet positioned
centrically around the float cage.
