Above-ground oil/water separators offer ease of maintenance and visual inspection, while below-ground separators are preferred for space constraints and potential spill containment. Above-ground units are typically easier to access and maintain, often involving simple cleaning with a hose or pressure washer. Below-ground systems can leverage gravity for inlet flow and may be necessary in areas with limited space or existing infrastructure.
The following comparison highlights the key pros and cons of above-ground and below-ground oil/water separators.
| Above-Ground Oil/Water Separators |
Below-Ground Oil/Water Separators |
Pros
- Ease of Maintenance: Above-ground units are easily
accessible, allowing for simple cleaning and inspection.
- Visual Inspection: The location allows for easy
monitoring of the separator’s performance and any potential issues.
- Greater Variation: Systems can be for particular application with different sizes and options.
- Cost-Effective Maintenance: Maintenance is often less expensive
than underground systems.
|
Pros
- Space-Saving: Minimizes the use of valuable surface space
- Gravity Flow: Gravity can be utilized for wastewater inlet, reducing the need for pumps and controls.
- Ideal for Large Flow Rates: Well-suited for handling high
volumes of oily wastewater.
- Suitable for Spill Containment: Can be designed for spill
containment in various applications, such as vehicle maintenance.
|
Cons
- Space Requirements: Require more surface space than
below-ground systems.
- Pumping Requirements: May require pumps and control systems to transfer wastewater into the separator, which adds to initial costs, maintenance and noise levels.
- Potential for Unsightliness: May not be desirable in areas where aesthetics is a concern.
|
Cons
- Maintenance Challenges: Maintenance can be more
complex and potentially hazardous due to confined space.
- Potential for Leaks:Underground piping systems may be vulnerable to leaks into groundwater, requiring double-walled tanks and piping.
- Higher Initial Costs: May have higher initial
installation costs compared to above-ground systems.
