An Oil and Grease Trap, also known as a Grease Trap or Grease Interceptor, is a specially designed system used to separate oil, grease, fats, and food solids from wastewater before it enters the drainage or sewer network. At Daichi Kurita Aqua-Air, our oil and grease traps are engineered to prevent pipeline blockages, reduce maintenance issues, and improve the efficiency of downstream wastewater treatment systems.
Wastewater generated from kitchens, food processing units, restaurants, hotels, and industrial operations often contains oil, grease, and suspended food particles. If these substances are allowed to enter drainage systems directly, they can solidify over time, causing choking, foul odors, and operational disruptions. Our grease trap systems effectively separate these contaminants at the source, ensuring smoother wastewater flow and better system performance.
How It Works
The oil and grease trap works on the principle of gravity separation:
Wastewater enters the trap chamber.
Heavier solids settle at the bottom of the tank.
Oil, grease, and fats rise to the surface because they are lighter than water.
The relatively cleaner water flows out through the outlet, while grease and solids remain trapped inside for periodic removal.
