Petroleum Drum Cleaning and Recycling Facility Optimizes Oil Recovery with SAMCO Treatment Solution

Project Overview

When a leading petroleum drum cleaning and recycling facility in South Carolina needed to optimize oil recovery from its wastewater streams, SAMCO delivered a wastewater treatment system (WWTS) designed to support up to 70% recovery, yielding a rapid return on investment.


Treat wastewater streams from petroleum oil drum cleaning operations to meet stringent discharge limits and recover valuable waste oil for resale.

Scope of Service

SAMCO delivered a turnkey WWTS to suit the client’s environment, beginning with a pilot treatability study, and comprising detailed engineering, system fabrication, controls integration, and startup support.


  • Stringent discharge testing limits for biochemical oxygen demand (BOD) and chemical oxygen demand (COD)
  • Exceptional durability for extended equipment life
  • Limited operator availability


SAMCO engineered a turnkey 50 GPM WWTS for integration into a new petroleum oil drum recycling line at the client facility. Designed to optimize recovery of oil from wastewater streams, the WWTS included a pre-rinse washer station with oil-water separation (OWS) technology for efficient segregation of waste streams prior to treatment and discharge. In achieving recycle/reuse rates of up to 70%, and reducing chemical feeds, the solution yielded rapid, single-year payback. To ensure lasting durability, the OWS and washer stations featured corrosion- resistant SAE 304 stainless steel construction. The modular WWTS design also allowed for expansion loads and future growth, and was outfitted with programmable logic controls (PLC) to minimize on- site operation and maintenance demands while providing process monitoring capabilities.



WWTS components included:

  • SAE 304 stainless steel OWS, pre-rinse, and drum washer stations
  • Equalization, de-emulsification and pH neutralization reactor
  • Oil handling and collection tank
  • Oil transfer, high pressure, and influent pumps
  • Chemical feeds
  • PLC controls
