The Water Remediation Challenge: Part of the International Terminal of the Port of Newport, Oregon was originally built on a sunken ship: the 1940s era S.S. Pasley. Decades later, hydrocarbons had started to leak from the deteriorating vessel.
The Baker Remediation Solution: Petroleum-impacted water from the ship — as well as from the operation’s high-pressure steam cleaning — was pumped into two 21,000-gallon open top Baker tanks. Next, it went through a 5000-gallon equalization tank, a transfer pump, a multi-unit sand filter skid, and a duplex cartridge filter (2 skid units, in parallel). Finally it travelled through two parallel skids of granular activated carbon/Organoclay® filters, each skid with a primary and a secondary filtration vessel in series. The treatment plant met all applicable regulations, including inspection by the Oregon Department of Environmental Quality (DEQ), with discharge to a nearby, ocean-bound sewer.
