Separating tanks are primarily used to separate oil and water. It is also called a grease trap or a gasoline trap. Oil and water are separated using the difference in specific gravity. Due to the difference in specific gravity, oil floats against water, and the floating oil is adsorbed using adsorption mats. In addition, by separating the tanks with shielding plates and passing them through in sequence, the amount of oil can be gradually reduced while also removing foreign matter, etc.
As dirt inevitably accumulates with use, regular maintenance is important.
Separating tanks are used to separate oil and water contained in wastewater. In recent years, as awareness of environmental destruction and legislation has increased, oil-water separating tanks have been introduced in various locations where oil may spill. In particular, they are widely used in automobile factories, maintenance shops, gas stations, car washes, and other places where automobile-related work is performed.
In addition, some laws require the installation of separate tanks in the kitchens of restaurants and other places where oil may spill into the sewerage system.
The following is an explanation of the principle of separating tanks, which separate oil and water. Separating tanks use the sinking property of water, which has a higher specific gravity than oil, to separate oil and water.
The inside of the separating tank is divided into about four sections by shielding. The first step is to pass through the dust trap and move to the next tank. The dust trap removes debris and foreign matter to prevent excess debris from accumulating in the tank.
The upper part of the separated tanks is designed to pass through an adsorption mat, which absorbs any oil floating on top. In addition, the flow between the tanks is through a shielding plate and tubes, which are arranged in alternating directions for efficient separating tanks. Many products place an oil checker in the last tank to check for oil residue before draining.
If the separating tank is not cleaned regularly, mud and debris may accumulate, preventing the separation function from working properly and preventing purification.
Products with FRP (Fiberglass Reinforced Plastic) inside the separating tank are particularly easy to install because they are corrosion resistant and easy to machine.
