Double wall polyethylene grease-traps
Fats and oils are one of the most common pollutants in various types of sewerage. Sometimes the amount of fat and oil is so high that the use of grease-trap to remove oils and fats is necessary. Usually sewerage such as sewage of kitchen, restaurants and carwashes are of this type. Gravity floating due to efficiency and cost-effective, today in most cases is used to remove fats and oils from sewage. Because the specific weight of oil is less than that of the sewage, these particles tend to float on the surface of the sewage. In order to carry out this process, it is only necessary to provide a mild and gentle environment for sewage. Polyethylene grease-traps are designed and constructed according to this simple, yet key principle.
