General Advice
(excerpt DIN EN 1825-2)
•
Only waste water containing fat and grease of plant and animal origin may enter the
grease separator.
•
The adequate connecting height of the existing drains needs to be checked.
•
The materials of the inlet and outlet pipes need to correspond with DIN EN 12056 and
must be resistant against the waste water according to DIN EN 1825-2. The required
cross section of the pipes which depends on the nominal size of the grease separator
needs to be observed.
•
The effluent needs to enter the grease separator in gravity fall. If the rest water level is
below the backflow level (see EN 752-2) a lifting plant needs to be installed.
•
In order to avoid grease settlement in the inlet pipes they need to be laid with a slope
of at least 2% (1 : 50) and they should be easy to clean.
Technical regulations to be observed:
•
DIN 1986 draining plants for buildings and estates, section 30, 100
•
DIN EN 752 draining systems outside of buildings, section 1-7
•
DIN EN 1825 grease separators for fatty matters, section 2
•
draft DIN 4040, section 100
•
DIN EN 12056 draining plants by means of gravity in buildings, section 1-5
•
DIN 1988 technical rules for tap water installation
WARNING
The valid standards for the installation and connection to the draining system need to be
observed.
1.1 Purpose of Use
Grease separators separate fatty matters and grease of vegetable and animal origin from
waste water by means of gravity.
The following liquids may never enter grease separators:
•
foul water („dirty water“)
•
rain water
•
waste water containing light liquids, e.g. fatty matters and grease of mineral origin
