What is an Automatic Grease Separator?

　　A grease trap or grease trap, both are the same. If it has a grease removal function or a grease conversion device, it can also be called an Automatic Grease Separator device. So, what exactly does it do? The grease trap is a pipe fixing device (part of the piping system) used to trap fat, oil, and grease, and to make the wastewater flow smoothly through the drainage system. In other words, it separates solid waste and grease from liquid waste. The grease recovery device or grease removal device of the Automatic Grease Separator Manufacturer is a grease trap with a built-in mechanism or process for removing the captured grease and storing it in a separate external container. These devices usually have solid filters. The main advantage is that the device does not need to be pumped anywhere as frequently as traditional grease traps. The grease trap is a box-shaped container made of stainless steel, plastic, cast iron, or concrete. It is installed between the kitchen sink and the sewer system. It is placed in such a way that only kitchen wastewater can pass through, which means that it cannot serve the entire drainage system, which also includes waste from toilets. The size of the grease trap ranges from 35 liters to 45,000 liters or more. These can be found inside industrial kitchens (under the counter), outside buildings (which can be located above or below the ground). But how do these work? Let's take a look at the science behind its function. It cannot provide services for the entire drainage system, which also includes waste from toilets.

　　How does the grease trap/interceptor work?

　　The grease trap is a pipe fixing device in which all solid fat, grease, and mist accumulate. It is a tank-like structure that allows hot wastewater from the kitchen sink to enter. Traditional grease traps are also called passive grease traps, and they work according to the principle of gravity. When the hot wastewater enters the grease trap, it acts as a reservoir and controls the flow of water until the grease is separated from the wastewater. However, the flow of water is not controlled by the trap, but by the internal baffle or control unit, which slows down the flow of wastewater. At the same time, hydrolysis occurs inside the grease interceptor. A process in which complex solid particles decompose due to reaction with water. In short, when the temperature of the wastewater decreases, the mist begins to separate. The mist is broken down into glycerin and fatty acids. Because glycerin has a higher density than water, they settle at the bottom as solid fat. Fatty acids are lighter than water and float on top. In between is wastewater. Once the glycerin and fatty acids are separated by gravity, the grease trap will allow the remaining wastewater to flow out of the pipe from the water tank smoothly. The separation speed of fats (fatty acids and glycerol) largely depends on factors such as temperature, viscosity, fat particle size, and retention time. For the best function of the grease trap, it is essential to use standpipes, internal baffles, and flow control devices. These additional units maximize retention time and provide more space by extending the flow path. At a later stage, the flow control device also allows air to be mixed to effectively separate the grease from the wastewater. These additional units are installed on the inlet side of the grease collector. Larger traps are passive traps that are completely dependent on the gravity mechanism. The smaller traps used indoors are called hydromechanical grease interceptors. In the grease removal device, the trapped grease is usually skimmed into an external container.
