Every Challenge Has a Backstory 

A petrochemical facility with complex and varied operations faced unique challenges in the management of its process wastewater. The facility’s waste streams contained PFAS and residual regulated compounds even after biological treatment. In addition to PFAS, wastewater from the onsite hazardous waste incineration operations contained elevated levels of mercury. 

Focus on Solutions

Ramboll completed an initial study of available technologies, stream sampling and onsite treatability testing. Based on these results, Ramboll’s team identified granular activated carbon (GAC) as a cost-effective technology to address both the organics-bearing and mercury-bearing waste streams. The project included front-end and detail design engineering, construction support and startup services for installing the new system at the facility.  

Results that Matter

Ramboll’s integrated approach to wastewater management allowed for a comprehensive solution in a single new installation at the site. The facility was one of the largest industrial GAC treatment systems in the US at that time, utilizing over 26 vessels containing 20,000 lbs each of installed GAC capacity to treat a combined flow of over 3 mgd. The installed treatment system was commissioned, started and has since been expanded to increase treatment of additional site discharges containing fluorinated organics.
