Description of Services:In October 2011, the Facility will start a transition to discontinue the acceptance of all outside (non-DuPont) customer wastewater. Wastewater treated at the Organic Recovery Operation unit (OREO, Steam Stripper) will end effective October 21, 2011; and all remaining current commercial wastewater treated directly at the Wastewater Treatment Plant (pump pit, heavy metals, secondary, etc.) will discontinue effective March 30, 2012. According to the Facility POC, this decision is for purely economic reasons. The Facility is not closing but will continue to operate and treat DuPont-generated wastewater.

The DuPont Chambers Works is a very large chemical plant for the manufacture of organic chemicals and intermediates; it comprises 1,440 acres. The wastewater treatment facility treats commercial wastewater generated at the Chambers Works, as well as wastewater brought to the facility by outside, third parties. Third party wastewater accounts for about 3% of the total amount treated by the facility (although it represents up to 90% of the organic loading). The incoming wastewaters may be hazardous (either listed or characteristic) or nonhazardous. They may be inorganic or organic, but they must be pumpable liquids. In addition to the process wastewater and stormwater, the total throughput also includes relatively small volumes of leachate from the onsite Subtitle C (referred to by DuPont as the “Secure”) Landfill.

The overall treatment train varies depending on the waste stream; however there are typically three steps that can be performed. In addition, there is pretreatment available, consisting of steam stripping.

  1. The first stage, or primary treatment system, consists of pH adjustment followed by precipitation and clarification.
  2. The second treatment stage, or secondary system, is an activated sludge, biological process with the addition of powdered activated carbon treatment (PACT).
  3. The third treatment stage, or tertiary system, is also an activated sludge, biological process with PACT enhancement. The overflow from the tertiary clarifiers is discharged to the Delaware River under the provisions of the facility NJPDES Permit.
