JFC Grease Trap

GREASE TRAPS

Rotational Moulders providing State of the A major problem in the drainage systems of dwelling
Art Product Design and Developement. houses, restaurants, bars, etc. is the build up of
grease and waste solids.
The JFC Grease Trap system is designed:
While the grease is still warm it flows freely but once
it cools it solidifies and eventually blocks the pipes.

Therefore it is necessary to remove this grease at an
early stage from the drainage system. This procedure

also minimises pollution of the waterways. The solu-
tion is the JFC Grease Trap. The grease trap can be
easily installed in new and existing waste water sys-

tems where 110mm piping is already being used.

To prevent waste water pipes from blockages.
To fit unobtrusively below ground level.
To allow ease of maintenance.
To allow reduced depth excavation.
For a long trouble free life and is
manufactured from recyclable material.

40 ltr Domestic Grease Trap GTO1

How it operates

When the wastewater enters the grease trap, the grease rises to the top
of the water level and eventually solidifies to form a hard layer at the
surface. The heavier waste solids are deposited in the perforated filter-
ing bucket, which sits firmly at the bottom of the grease trap chamber. Its
handle extends past the waste water level to prevent the user from com-
ing into contact with the contents of the grease trap when emptying.

After the wastewater passes through the filtering bucket it then exits
the grease trap through an outlet pipe and continues through the
drainage system. When necessary the filtering bucket can be removed
and the grease and trapped solids can be properly disposed of. It is
recommended that the grease trap be inspected regularly to ensure
proper maintenance of the system.

200 ltr Commercial Grease Trap GTO2

Stage 1
Inlet Chamber:
The wastewater flows into the inlet
chamber where the heavier waste solids
are retained in the perforated filtering
bucket. At this stage some grease may
solidify and rise to the top to form a layer
of sludge. There is a baffle to retain any
un-trapped solids in this chamber.

Stage 2
Settlement Chamber:
The wastewater flows under gravity from
the inlet chamber into this chamber. The
settlement chamber acts as a buffer zone
where the wastewater will circulate by
natural currents to cool the remaining
grease. Then the wastewater flows
forward into the outlet chamber.

Stage 3
Outlet Chamber:
This chamber collects the remaining
grease from the wastewater and retains it
in the perforated filtering bucket. The
wastewater flows under gravity through
the outlet. Again there is a baffle to retain
any un-trapped solids in this chamber.

It is not recommended to install JFC greasetraps inside, unless appropriate double sealed access covers are used.
Suitable access covers are available from hardware or heating / plumbing stores.

Installation

Excavate a hole as follows:

Length = 950mm

Width = 550mm

Depth = 820mm min. below path

or finished surface level.

This includes an allowance of 75mm for
a concrete base underneath the grease

Install the grease trap (1) into the pit and
connect it to the appropriate branch drain
(11).

The riser (6) is then inserted into top collar
(9) and due to variations in ground level it
may need to be trimmed or an additional
riser may be necessary.

When Fitting J.F.C Grease Trap (GTO1) in driveways or areas of heavy motorised traffic, it is necessary
to fit a JFC Riser / Extension and set it centrally in a square concrete (30 N) slab, 750 mm x 750 mm x 150 mm

deep to support higher weight loads.

Cleaning Procedures:

Proper maintenance requires frequent monitoring and cleaning of the greasetrap. After
installation the greasetrap should initially be inspected twice weekly and emptied as
required. When the greasetrap is in operation for some time a pattern of emptying will
develop which will determine the frequency of inspection/cleaning.

GT01 Maintenance:

To remove the grease and solids that are trapped in the filtering bucket, simply open
the access cover and extract bucket from the main chamber. As there are holes in the
bucket, when you are removing it the wastewater will escape and you are then left with
the deposited solids. As you are removing the bucket you are also removing the
grease and oil that has built up on the surface. Remaining oils on the surface will have
to be removed by skimming with a ladle or similar item. Dispose of the contents of the
bucket properly and place it back in the chamber of the grease trap again. Remember
not to have any appliances or taps in operation when you are cleaning the grease trap.
The greasetrap should then be primed with clean water to the working level of the trap.

GT02 Maintanence:

To remove the grease and solids that are trapped in the filtering buckets, simply open
both access covers. The chamber nearest the inlet is for collection of solids, (food
particles, fats etc) to clean this chamber remove the filtering bucket from this chamber.
As there are holes in the bucket when you are removing it the wastewater will escape
and you are then left with the deposited solids, grease and oil. The outlet chamber is
for collection of non-soluble greases. To clean this chamber remove the filtering bucket
from the chamber. As you are removing the bucket you are also removing the grease
that has built up on the surface. Remaining oils on the surfaces will then have to be
removed by skimming with a ladle or similar item. Dispose of the contents of the
buckets properly and place them back in the chambers of the grease trap again.
Remember not to have any appliances or taps in operation when you are cleaning
the grease trap. The greasetrap should then be primed with clean water to the working
level of the trap.
