Reduced performance and damage to the coalescer panels, secondary coalescer, and other components may occur if the unit is not properly maintained. A maintenance plan for AquaSweepTM gravity oil water separator should include:
- Periodic inspection to check for and remove the oil, sludge, sand, and other sediments in the tanks’ compartments.
- Periodic inspection and replacement of coalescing media.
- Check for free oil in the effluent after heavy rainfalls to verify effective separator and alarm operation.
- Periodic monitoring of the effluent for free oil. Check for oil in the effluent.
Care must be taken when entering the AquaSweepTM Oil Water Separator. Surfaces will be slippery and flammable and combustible vapors may be present. Follow all local codes and OSHA guidelines concerning entry into confined spaces.
|1.0||Upstream interceptor (if present): Frequently examine for and remove heavy debris common in storm water run-off. Remove any material, such as paper, vegetation, etc., that would obstruct the separator’s inlet piping or impede the separator’s performance.|
|3.0||Primary Coalescer Containment: At least annually, in conjunction with servicing the sediment chamber, replace or clear the inlet pipes and coalescer plates or packs of oil/grease accumulations with a suction hose or portable oil pump and pressure spray or steam clean the plates and packs as necessary. Do not use soaps or detergents to clean the plates or packs since this will introduce emulsifiers to the unit. Clean the coalescer compartment as needed to prevent an accumulation of sediment that would impede oil water separation. Inspect the interior tank coating (if applicable) for damage and repair as necessary. Inspect components for damage and replace if necessary.|
|6.0||After all of the servicing has been performed on the tank, completely fill the separator with clean water. The unit is now ready to be returned to service by following the “Start-up Instructions”.|
|7.0||Aboveground separator requirements: The separator operator should perform periodic walk-around inspections to identify and repair areas of damage to the vessel or the coating itself and check for proper drainage around the separator area.|
|7.1||It is imperative that the separator exterior be inspected periodically to ensure that the integrity of the coating is maintained. The frequency of periodic repainting will be based upon environmental factors in the geographic area where the separator is located. Special consideration should be given to the selection of the paint, surface preparation and coating application. The coating selected should be suitable for use with the current coating, or the existing coating should be removed. The coating selected should be of industrial quality.|
