MAINTAINING THE AQUATOR
The Aquator requires regular maintenance, including the following cleaning and inspection procedures,
to operate most efficiently and effectively.
Never enter the Aquator, the riser, the manway extension or any other enclosed space without
proper training and OSHA-approved equipment.
Aquator internal surfaces are slippery.
Ventilate all enclosed spaces according to methods described in applicable regulations and codes
before entering an Aquator to avoid asphyxiation or ignition of vapours or liquid oil, which are
flammable.
Perform maintenance at three, six or twelve monthly intervals depending upon the site conditions.
Under the following conditions, maintenance is required more frequently:
•
If the Aquator bottom sludge accumulation is more than 30 cm deep;
•
When the effluent water quality does not meet levels mandated by applicable federal, state and
local codes and regulations;
•
After a major oil spill has occurred.
Begin maintenance by cleaning the Aquator, using the following procedure:
Remove the coalescing filter for cleaning. Use normal water pressure, ensuring the dirty water runs back into
the drainage system leading to the Aquator.
Do not stand on the coalescing filter support grating. This grating is not designed to accept
loads and is slippery.
Sludge and debris should be removed from the Aquator using a vacuum truck .
Do not use picks, axes, hammers or other heavy tools or objects when breaking apart sludge in
the Aquator. Such tools may damage the Aquator.
Do not use detergent or soap.
Do not use soaps or detergents when cleaning the coalescing filter. Soaps or detergents may
damage the coalescing filter and/or reduce the efficiency of the Aquator.
Check the oil/water sensor (if installed) for movement.
Remove and clean the sensor as per manufacturers instructions if the sensors are fouled. This is usually
simply a matter of wiping and reinstalling.
Visually inspect the Aquator interior (walls, components and inlet piping) for damage. If you observe any
damage, contact the Tank Solutions.
If entry to the Aquator is required, remove all liquid from the Aquator and isolate all inlet and outlet pipework
and valves.
Properly dispose of oil removed from the Aquator as required by federal, state and local laws,
codes and regulations.
Failure to close inlet and outlet piping valves or plug the piping before entering the Aquator could
result in death or serious injury.
