The MYCELX separation system removes petroleum and metals

Case Study: Philadelphia Naval Shipyard
Military/Naval Aircraft Carriers & Battleships are decommissioned dockside at the
Philadelphia Naval Shipyard. On the ships are large volumes of petroleumimpacted water in the bilge & ballast sections. This water must be treated prior
to discharge or hauled away for treatment off-site. In this case, the shipyard was
treating the water off-site or ex-situ at $0.25 per gallon, plus transportation and
The MYCELX HRM system was installed and removes petroleum and metals
from off-loaded/dock-side bilge & ballast water at 220 gpm. The system consists
of an automated gravity oil-water separator (OWS), particle filtration, (2)
MYCELX MX-22 HRM Cartridge units in series, and a 20,000 gallon hold tank
(Fig. x). The operators monitor breakthrough of the primary MYCELX unit by
sampling and checking for odor & sheen. Upon breakthrough, the primary
MYCELX cartridges are replaced with the downstream (secondary) cartridges,
and fresh cartridges are added to the secondary MYCELX unit. This operating
procedure virtually guarantees performance & eliminates any contamination in
the hold tank. The treated water is discharge to the sanitary sewer system after
passing standards set by the city.
As designed, it will cost about $0.02 per gallon after the OWS to purify the
bilge/ballast water. Our Government should save roughly $200,000 for every
1,000,000 gallons they treat with the MYCELX system versus having the
contaminated water hauled away.
