Process Description: A belt oil skimmer is a mechanical device designed to continuously remove floating oil, grease, and other hydrocarbons from the surface of water in industrial effluent treatment plants, machine sumps, and oil-water separators. The skimmer operates by rotating a continuous belt—typically made of stainless steel, poly, or elastomer—through the contaminated liquid. Oil adheres to the belt's surface and is then wiped or scraped off as the belt passes through a set of wipers or scrapers, allowing for efficient oil recovery and improved water quality.
Oil Removal Parameters:
Inlet Oil Characteristics:
- Oil Layer Thickness: 1–10 mm (typical);
- Oil Type: Light, medium, or heavy oils;
- Temperature: 5–60°C; pH: 5.0–9.0.
Outlet (Recovered Oil) Quality:
- Oil Purity: Up to 95% oil with minimal water content;
- Residual Oil in Water: Can be reduced to less than 10 ppm, depending on application and skimmer design.
Capacity Range:
- Small-scale units: 1–5 litres/hour.
- Medium-scale units: 5–25 litres/hour.
- Large-scale units: 25–100 litres/hour or more, depending on belt width, length, and application.
