Oil Skimmers are mechanical devices used to remove oil or other hydrocarbons from the surface of water. They are commonly used in industrial settings, oil spill cleanup, and wastewater treatment plants to recover valuable oil, prevent pollution, and maintain cleaner water systems.
How Oil Skimmers Work:
Oil skimmers rely on the principle that oil floats on water and adheres more readily to certain materials than water does. These devices collect the oil from the surface and then separate it for disposal or reuse.
Types of Oil Skimmers:
- Belt Skimmers
- Use a rotating belt made of oleophilic (oil-attracting) material.
- Ideal for small tanks, sumps, and CNC machines.
- Tube Skimmers
- Use a floating tube that moves across the water surface.
- Good for larger surface areas or irregular-shaped tanks.
- Disk Skimmers
- Use a rotating disk partially submerged in water.
- Simple and cost-effective for light oil layers.
- Drum Skimmers
- Use a rotating drum that collects oil as it spins.
- Suitable for high-capacity and industrial applications.
- Weir Skimmers
- Use a floating barrier or “weir” to let surface oil flow over it.
- Best for thick oil layers or oil spill recovery.
Common Applications:
- Machine coolant tanks
- Oil-water separators
- Industrial wastewater treatment
- Oil spill recovery (marine or on land)
- Food processing plants
- Steel and manufacturing industries
Benefits of Using Oil Skimmers:
- Reduces environmental contamination
- Saves costs by recovering reusable oil
- Improves water treatment efficiency
- Low maintenance and easy to operate
- Extends life of coolants and wash water
Oil Skimmer for STP (Sewage Treatment Plant)
An Oil Skimmer in a Sewage Treatment Plant (STP) is used to remove floating oils, grease, and other hydrocarbons from the surface of water before further treatment. This helps improve the efficiency of the treatment process and protects downstream equipment.
Typical Installation Areas in STP:
- Oil & Grease Trap
- Equalization Tank
- Primary Clarifier
- Collection Sump
