5. Description
5.1. Grease separator WNG-S1/S2
A grease separator is used wherever greasy wastewater is to be expected. The grease separator separates fats, oils and
sludge from the wastewater. Thanks to the flushing and disposal device, the grease separator can be disposed of with
almost no odor nuisance, since the odor-tight closed system does not have to be opened for this. The hose of the disposal
vehicle can be connected to the permanently installed disposal line, which is led to an easily accessible point. The separa-
ted fats are pumped directly into the disposal vehicle. This eliminates the time-consuming and unhygienic laying out of the
disposal hoses through utility and storage rooms (e.g. food areas). In addition, there is no odor nuisance there

5.3. Intended Use
The separator system is intended exclusively for the separation of saponifiable oils and fats of vegetable and animal origin.
Any use going beyond this is considered improper. The manufacturer is not liable for any resulting damage; the user alone
bears the risk!
Animal and vegetable oils and fats must not be discharged into public waste disposal facilities or waters, as they cause
cross-sectional constrictions and blockages in the disposal lines when cold. Furthermore, after a short decomposition
time, fatty acids are formed, which lead to unpleasant odors and attack pipes and structures in the drainage system. The
solidified layer of fat on the surface of the water also inhibits the necessary oxygen supply in waters and sewage treatment
plants. In addition, DIN1986 Part 1 requires the retention of harmful substances. For these reasons, grease separator sys-
tems must be provided that must be disposed of accordingly. The temperature in the separator should be as low as possib-
le. With an increase of 10 ° C the separation efficiency is halved.
Compliance with the operating, maintenance and repair conditions prescribed by the manufacturer is also part of the inten-
ded use.
6. Installation
6.1. Installation site / requirements
Free-standing installation in frost-free rooms
Before installing the grease separator, check the following:
Separation systems should be installed near where the waste water occurs. Furthermore, the suction connection for clea-
ning vehicles should be easily accessible.
• The system should not be set up in the vicinity of common rooms, especially not in the vicinity of windows or ventilation
openings, so that unpleasant smells are avoided
• It is easy to reach for cleaning vehicles
• Room with good air circulation and / or ventilation as well as an even and sufficiently stable installation surface
(observe stability / ceiling load)
• Room temperature at least 15°C.
• Sealed floor covering with integrated drainage point.
• Hot and cold water connection
• Room height at least 60 cm higher than the grease separator system, so that the revision lid can be opened during
cleaning work.
• Free working space, at least 1 m, in front of the grease separator system.
• The wastewater is to be fed to the separator system for grease in a free gradient
• Inlet with calming section of min. 1 m (slope 1:50). Transition from on-site downpipe to the calming section equipped
with 2x 45° bends DN 250 at least
• If the supply line is longer than 10 m, it must be vented separately.
• Foreign objects (cutlery, crown corks, mustard bags, bones, etc.) interfere with the separation process
• In areas at risk of flooding, the system can be secured against floating
6.2. Mounting
• Install inlet and outlet
• Establish pipe connections to the house installation at the inlet and outlet.
• Make sure that the seals are sufficiently greased.
• The pipe materials used should be resistant to animal and vegetable fats, oils and their degradation products (seal
made of NBR, high temperatures).
Immediately at the outlet of the separator and before mixing with other wastewater, a device for sampling and inspection
must be installed (depending on the version already included in the scope of delivery)
The sampling point or facility of the separator system must be freely accessible and arranged in such a way that only
wastewater that has passed through the separator system is sampled
6.3. Backflow-free installation
Separator systems for fats whose still water level is below the backflow level must be drained via downstream lifting
systems
• Where aplicable mount the direct disposal pipe - The disposal pipe provided for emptying should have a diameter of at
least 50 mm inside width
• The choice of the pipe material for the disposal line should be based on the waste water content (extremely high solid
content) and the particular operating situation (overpressure / underpressure).
• The disposal line from the grease separator to the transfer point to the disposal vehicle should be laid with a steadily
rising gradient. Changes in the direction of the line through 90 ° bends should be carried out with a large radius if
possible

8
• The disposal line must be able to be closed odor-tight (e.g. Storz-B coupling).
• Use tensile strength connections between the individual pipes and fittings
6.4. Ventilation duct
• The inlet and outlet lines on separator systems for grease must be adequately ventilated
• For this purpose, the inlet pipe is to be run as a ventilation pipe over the roof. All connection lines longer than 5 m
must be vented separately
• No other ventilation systems may be connected to these ventilation lines
• The ventilation line of the supply line and, if necessary, the grease separator can be combined to a collective ventilation
system
6.5. First filling and pressure test
• Make sure that there are no foreign substances or impurities in the grease separator.
• Fill the entire grease separator system completely with water.
• Carry out a pressure test by opening both inspection lids.
• Close the outlet and inlet with appropriate means.
• Fill the grease separator system completely with water and ensure that there are no leaks.

The dates and results of the self-checks, maintenance and inspections carried out, the disposal of removed ingredients
(filing of the disposal evidence from the disposal company) as well as the elimination of any deficiencies are to be documen-
ted in the operating log. The operating log and test reports are to be kept by the operator and, upon request, shown to the
locally responsible supervisory authorities or the operators of the municipal sewage systems.
Note
The timely and regular emptying, cleaning and maintenance of the grease separator system
guarantees perfect functioning.
Important
Emptying and cleaning intervals
Kitchen fats and oils form fatty acids within a very short time, which must not get into the sewage system. Accordingly
the emptying and cleaning intervals are to be determined so that the storage capacity of the separator and the sludge
trap is not exceeded.
Unless otherwise requirde by ordinances and other requirements, cleaning and maintenance must be carried out in accor-
dance with the operating instructions.

Beschreibung der Abscheiderkonstruktion
Der Abscheider, der auf der Zeichnung 1 dargestellt ist, hat die Form eines Quaders
mit den Abmessungen 600 x 1850 x 970 mm (B x L x H). Er wurde aus 2 mm dickem
säurebeständigem Stahl 1.4301 nach PN-EN 10088-1 gefertigt. Die Abscheiderwände sind mit einem Band verstärkt. Die Geometrie des Abscheiders wurde vom Auftraggeber übergeben. Der Abscheider wird im Innenbereich eingesetzt.

Die GZG-Bedienung wurde durch den Vergleich der maximalen Durchbiegung der Behälterwände mit den zulässigen Werten geprüft (angenommen L/200, wobei L ist die kürzere
Seite der Wand).
4.4. Beschreibung des Rechenmodells
Die Berechnungen des Abscheiders wurden mit der Finite-Elemente-Methode durchgeführt. Die vom Kunden bereitgestellte Geometrie wurde in das FEM-System eingeführt. Der Abscheider wurde mit flachen Vier-Knoten-Finite-Elementen modelliert. An den Füßen des
Unterbaus wurde verhindert, dass es zur Verschiebung in vertikaler Richtung kommt. An die
Behälterwände kam von Innen hydrostatischer Druck (Flüssigkeitsdichte wurde gemäß Abschnitt 3.1 angenommen). Bei den Berechnungen wurde auch das Eigengewicht der Konstruktion berücksichtigt. Geometrische Nichtlinearität (große Verformungen) wurde bei den Berechnungen berücksichtigt. Die numerischen Modelle wurden weder validiert noch kalibriert,
so dass die Ergebnisse der Berechnungen nicht mit den Ergebnissen von Tests an realen Objekten gleichgesetzt werden können. In Wirklichkeit können die Werte von Lasten, Verschiebungen und Verformungen etwas anders sein. Abbildung 2 zeigt das diskrete FEN-
Modell des Abscheiders, die Werte des auf den Abscheider wirkenden hydrostatischen Drucks und wie das Modell abgestützt wird.

Annahmen zur statischen Festigkeitsanalyse
4.1. Auf den Abscheider wirkende Kräfte In den numerischen Berechnungen wurden folgende Belastungen berücksichtigt: •Druck der Flüssigkeit an den Wänden des Abscheiders - U Bei den Berechnungen wurde angenommen, dass sich der Abscheider bis zur Höhe der Oberkante mit Wasser füllt. Angenommene Wasserdichte: rw= 1000 kg/m3
Für den charakteristischen Wert der Einwirkung wurde der Grenzzustand der Gebrauchstauglichkeit (GZG) und für den Bemessungswert der Einwirkung wurde die
Bedingung des Grenzzustands der Tragfähigkeit (GZT) nachgewiesen (für die Einwirkungen wurde 1,5-Faktor nach [1] angenommen):
rz= 1,5 * 10 kg/m3 = 1500 kg/m3.
Für die FEM-Analyse des Abscheiders wurde folgende äquivalente Dichte angenommen: rz= 1500
kg/m3
4.2. Mechanische Parameter des Stahls, die bei der Analyse angenommen wurden Für die Berechnungen wurden folgende mechanische Parameter des rostfreien Stahls 1.4301 nach PN-EN 10088-1 und 2 ([4], [5]) angenommen:
•Elastizitätsmodul E = 194 [GPa],
•Poissonzahl v = 0,3, •spezifisches Gewicht r = 7900 [kg/m3], •charakteristische Werte der konventionellen Streckgrenze (Ra) und Zugfestigkeit (Rm): Ra = 230 [MPa] und Rm = 540 [MPa]. 4.3. Bedingungen für Grenzzustände Der Nachweis der GZT-Bedienung erfolgte wie folgt: •Vergleich der maximalen reduzierten Spannung HMH infolge von Einwirkungen mit
Bemessungswerten mit der konventionellen Streckgrenze von Stahl (Teilsicherheitsbeiwert YMI = 1,0 wurde nach PN-EN 1993-1 angenommen), •Nachweis der Möglichkeit des Stabilitätsverlustes der Abscheiderwände (unter Berücksichtigung der geometrischen Nichtlinearität in der Analyse).

unter hydrostatischem Druck auftritt.
Abb. 3 Reduzierte Spannungsschichtung nach von Mises in MPa Bei der Analyse der in Abbildung 3 dargestellten Ergebnisse kann festgestellt werden, dass die maximale reduzierte Spannung sred = 131 MPa<Ra=230 MPa beträgt.
Der Sicherheitsfaktor ist =
Die Stabilität der Abscheiderwände wird nicht beeinträchtigt. Die GZT-Bedingung ist erfüllt.

Auf der Abbildung 4 sind die Verformungsschichten des
Separators dargestellt.
Abb. 3 Verformungsschichten des Separators in mm
Bei der Analyse der in Abb. 4 dargestellten Ergebnisse kann festgestellt werden, dass die maximalen Verformungen (Durchbiegungen) des Behälters w =3.2 mm betragen. Grenzwert der Durchbiegung W=3,2 mm < Wdop = 4,85 mm
Die Bedingung für die Durchbiegungsgrenzen (GZG) wurde erfüllt.
6.
Schlussfolgerungen
In Anbetracht der Ergebnisse der durchgeführten FEM-Analysen kann festgestellt werden, dass: - die maximalen Spannungen in den Abscheiderwänden die zulässigen Werte nicht überschreiten – die GZT-Bedingung ist erfüllt, - die höchsten Durchbiegungswerte der Behälterwände keine Grenzwerte überschreiten - die GZG-Bedingung ist erfüllt.
