Oil and grease trap is used, when wastewater contain certain amount of oil and grease. They are installed in front of wastewater treatment plant or directly on the source of pollution. Oil and grease trap protect.
Drainwater containing free-floating grease and oils enters the MOBILAP through internal solids strainer basket collect food solids and other debris. Treatment process is based on principe of gravity. The lighter fats and oils immediately separate, rise to the top and remain trapped in the retention area of the tank. The heavier clean water portion of the flow is allowed to exit under the outlet baffle and is discharged into drain lines. At present time of day, determined by timer settings, the self cleaning process is started. When it first starts, the electric heating element is activated and heats the system to 45-60°C. This ensures that all fats and oils are liquefied before they are automatically removed from the retention area of the tank. This heating process also helps to prevent bacteria growth within the system which is a major cause of odor. After the tank has reached the desired temperature, the motor which rotates the skimming wheel is activated. Wheel is made of a special type of material, which causes grease and oil to adhere it. A wiper blade assembly, which fits over the wheel, removes the grease and oils from the wheel and transfers them to the outlet sump pipe. The skimmed grease and oils flow through this pipe to the outside of the system and are collected in the collection container.
