AB  - Food Oils and Grease (FOG) which is
discharged to the sewage network, increases the pollution
indicators (BOD, COD). Therefore, the negative impact
on sewage network systems is very important in general
and in particular on water treatment systems. In this study,
a laboratory and field study is conducted to determine the
impact of FOG distributed to the public sewage network
from a real case study in a quarter of Lattakia city-Syria.
Plastic bottles were distributed on a number of houses to
collect the oil usually transferred to the sewerage network.
The bottles were then collected after a specified period of
time. This step was accompanied by measure of some
indicators of pollution of oil waste (BOD-COD-FOG) in
two cases: before stopping the disposal of oils in the
sewer network and after the collecting of oils by
distributed bottles. It is identified, through laboratory tests
of indicators of sewage pollution, the negative impact of
oil and grease discharged to the public sewerage network.
The analysis of the results showed that stopping the
dumping of oils and grease in the sewage network
reduced the rate of wastewater contamination by 17% for
the BOD and 15.9% for the COD.
