An Oil & Grease Trap is a specialized wastewater treatment system designed to separate and capture oil, grease, fats, and floating contaminants from wastewater before it enters drainage networks, sewage systems, or treatment plants. These systems play a crucial role in preventing pipeline blockages, reducing maintenance costs, protecting treatment equipment, and ensuring compliance with environmental regulations. Oil & Grease Traps are widely used in commercial kitchens, restaurants, hotels, food processing units, automobile workshops, manufacturing facilities, and industrial plants where wastewater contains significant amounts of oil and grease.
At Azure India, we provide high-performance Oil & Grease Trap systems engineered to deliver reliable separation efficiency and long-term operational performance. Our systems are designed to effectively remove floating oils and grease while allowing cleaner water to pass through for further treatment or safe discharge.
The Oil & Grease Trap operates on the principle of gravity separation. As wastewater enters the chamber, the flow velocity decreases, allowing heavier solids to settle at the bottom while lighter oils and grease rise to the surface. The separated contaminants are retained within the trap, preventing them from entering downstream pipelines and treatment systems.
This simple yet highly effective process helps maintain smooth wastewater flow and protects critical treatment infrastructure from damage caused by accumulated grease and oil.
Our Oil & Grease Trap systems are suitable for a wide range of commercial and industrial sectors, including:
Azure is a leading Oil & Grease Trap manufacturer in Chhattisgarh, Assam, Arunachal Pradesh, and Delhi, supplying high-performance grease traps, oil separators, and FOG (Fat, Oil & Grease) interceptors for hotels, restaurants, hospitals, food processing units, automobile workshops, petrol pumps, and industrial facilities. Whether you need an Oil & Grease Trap in Raipur, Bhilai, or Durg in Chhattisgarh; Guwahati, Dibrugarh, or Jorhat in Assam; Itanagar or Naharlagun in Arunachal Pradesh; or anywhere across Delhi NCR — Azure delivers durable, CPCB-compliant grease trap solutions engineered for your specific application, capacity, and site requirements. Azure also manufactures a complete range of water and wastewater treatment systems including Effluent Treatment Plants, Sewage Treatment Plants, Water Treatment Plants, Ultra Filtration Plants, and Reverse Osmosis Plants across India.
An Oil & Grease Trap — also called a grease interceptor or FOG trap — is a plumbing device designed to intercept, capture, and retain fats, oils, and grease (FOG) before they enter the main wastewater drainage system or sewage treatment plant. When FOG enters drainage systems untreated, it solidifies inside pipes, causes blockages, damages Sewage Treatment Plants, and creates serious CPCB and state pollution control board compliance violations.
Azure manufactures Oil & Grease Traps in Stainless Steel (SS), Mild Steel (MS), Fibre Reinforced Plastic (FRP), and High-Density Polyethylene (HDPE) — available in a wide range of capacities from 50 litres to 50,000 litres, suitable for everything from a small restaurant kitchen in Itanagar to a large food processing plant in Raipur or a hotel chain across Delhi NCR.
If your business discharges any wastewater containing FOG — whether you operate a hotel, hospital canteen, food factory, automobile workshop, or petrol pump — you are legally required under CPCB norms and state pollution control board regulations to install a certified Oil & Grease Trap before your wastewater connects to the municipal drain or your onsite Sewage Treatment Plant. To understand how grease trap wastewater is further treated, read our detailed guide on Sewage Treatment Plants.
Chhattisgarh is an emerging industrial powerhouse with major steel plants, power plants, mining operations, food processing units, and a rapidly growing hospitality sector — all of which generate oil and grease-laden wastewater that requires proper treatment before discharge. Azure is a trusted Oil & Grease Trap manufacturer in Chhattisgarh, supplying grease interceptors and oil separators in Raipur, Bhilai, Durg, Korba, Bilaspur, Jagdalpur, Ambikapur, Rajnandgaon, and Raigarh.
Azure supplies the following Oil & Grease Trap types in Chhattisgarh:
– SS Grease Traps for hotel and restaurant kitchens in Raipur and Bilaspur

Understanding how an Oil & Grease Trap functions helps you choose the right type and capacity for your application. Here is a step-by-step explanation of the working principle:
Step 1 — Wastewater Inlet
Kitchen wastewater, workshop runoff, or industrial process water containing fats, oils, and grease enters the grease trap through the inlet pipe. The wastewater is slowed down as it enters the trap chamber, reducing its velocity and allowing the separation process to begin.
Step 2 — Gravity Separation
Inside the trap, FOG (fats, oils, and grease) naturally float to the surface of the water because they are less dense than water. Heavier solids such as food particles and sediment sink to the bottom of the trap, forming a sludge layer.
Step 3 — FOG Retention Layer
The floating FOG layer is retained inside the trap chamber, while the clarified water — now largely free of oil and grease — flows below the baffle wall toward the outlet. The baffle wall design ensures FOG cannot escape with the outflowing water.
Step 4 — Treated Water Outlet
The treated water exiting the grease trap is now significantly reduced in FOG content and can safely connect to the municipal sewer, your onsite Sewage Treatment Plant, or Effluent Treatment Plant without causing blockages or system damage.
Step 5 — Periodic Cleaning & Desludging
The retained FOG layer and bottom sludge must be periodically removed through cleaning and desludging — typically every 1 to 4 weeks depending on usage. Azure provides AMC and cleaning services for all grease traps supplied across Chhattisgarh, Assam, Arunachal Pradesh, and Delhi.
