PROCEPTOR
OWNER'S MANUAL
Maintenance: Coalescer
Regularly monitor oil and sediment level in your Proceptor separator.
When the separator is pumped out, Zurn Green Turtle recommends cleaning the coalescer system at the same time. The
coalescer may become plugged up if the loading solids are too high in the influent wastewater. Although this will not aect
flow through the separator, it may reduce the oil removal eciency and expose the Owner/Operator to unnecessary liability.
To clean the coalescer system:
1 Visually inspect the unit from the accessway to make sure there is no obstruction on top of the coalescer, and the lifting
device is secured. There may be tabs bolted on the bae to hold the coalescer in place during the original shipment.
Swivel them out of the way if they are holding the coalescer down.
2 Pull the handle gently to lift and remove coalescer pack(s) one at a time.
3 Use caution when handling the coalescer packs to avoid damage.
4 Inspect for damage. Ensure frames are intact.
5 Rinse each coalescer pack with low-pressure clean water. Note: Do not use soap in the cleaning process. Tip: Before the
separator is pumped out, suspend each pack over the tank accessway using a bar through the handle at floor level. The
rinse water will flow back into the tank and be pumped out by the waste maintenance company.
6 Look through the porous sides of the pack to ensure channels are clear. If low-pressure flow will not clear the channels
due to packed solids, a high-pressure wash may used. Use care not to damage the internal parts of the pack with a high-
pressure wash.
7 Ensure all oil, water and sediment is pumped out/removed from the oil separator until it is clean to the bottom.
8 Ensure the frames in the Proceptor bae inside the tank are free of debris, especially at the bottom where the coalescer
is installed.
9 Before refilling the separator with clean water, reinstall each pack by lowering carefully into the bae frame, making sure
pack(s) are seated and level with the top of the bae. When the coalescer packs are equipped with vertical guide bars (a
feature added in 2007), it prevents the packs from being reinstalled incorrectly. These bars protrude from the box frame.
Note: If the coalescer system does not have guide bars, ensure the pack(s) are installed with the open-celled sides facing the
inlet and outlet. The top and bottom of the packs also have open cells. If installed incorrectly, wastewater will flow over the
coalescer instead of flowing through it.
Refill the separator with clean cold water. Do not add soap
to the unit.
An alternative to pulling out coalescer packs is to pressure
wash them in place after the tank is pumped out during
scheduled maintenance. Please ensure the water used to clean
the coalescer system is also pumped out.
However, Zurn Green Turtle recommends removal of the
coalescer packs for optimal cleaning and inspection.
Repair
If a coalescer system appears damaged call your Zurn Green
Turtle representative for further information.
