What is Sewage Oil trapper?
The amount of fat and oil in sanitary sewage is usually lower than the amount needed to use fat and oil removal equipment. But most industrial wastewater such as refinery wastewater, petrochemicals, food industries, dairy industries, slaughterhouses, industrial kitchens and restaurants and so on, need sewage oil trapper to remove fat and oil. Floating method is used to remove fat and oil from water due to differences in oil and water density.
Different types of fats are widely used throughout the world in cooking, especially in industrial kitchens. In addition, in these kitchens, things like washing dishes, cleaning the kitchen, laundering all kinds of food, etc., can produce a lot of wastewater and fatty waste. (That’s why this device is also called a kitchen oil trapper or a restaurant grease trapper.)
Gravity Floating is one of the most efficient and cost effective methods used today in most wastewater grease removing systems.
The processes of flotation and removal of fat and oil are divided into two main parts:
Gravity separators are usually used to remove grease, oil and fat that are insoluble and non-emulsion in the effluent. The separation process in the gravity separators is based on the Sketoks law and by the difference in the density of the oil and fat droplets with water. In this process, oil and fat droplets rise and float on the surface of the water due to lower density. The gravity separators are mainly divided into two categories: API and CPI.
