Abstract
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.
