A polyethylene operator estimated more than USD one million (USD 1.20 to 1.40/gal) costs to dispose of toxic wastewater using offsite, hazardous waste treatment options. The operator recruited Halliburton to implement an environmentally acceptable alternative solution to lower costs and increase efficiency.
The operator’s wastewater contained a sulfide content greater than 400 ppm. Sulfide at this level is toxic to biological treatment systems, disrupting efficiency and causing effluent discharge excursions. The wastewater needed to be treated before entering the wastewater treatment plant.
Halliburton evaluated and implemented an onsite sulfidic wastewater oxidation solution at a significantly lower cost than offsite alternatives. This temporary, noncapital treatment approach uses hydrogen peroxide to eliminate sulfide, allowing the wastewater to be processed through the activated sludge system rather than transported offsite.
The oxidation solution increased wastewater treatment efficiency at the plant and eliminated the need for more expensive offsite hazardous waste treatment options. This process saved the operator approximately $280,000.
