Lummus Technology takes on difficult wastewater treatment problems for operators with its Zimpro® wet air oxidation system (WAO) and the Powder Activated Carbon Technology (PACT®) system, tailored solutions that can help increase performance, debottleneck, and allow for brownfield retrofits and greenfield opportunities. As the global leader in ethylene cracking technology, the Zimpro WAO process fits perfectly in helping treat spent caustic from ethylene production, processing the wastewater from the caustic scrubber and allowing for safe disposal or discharge.
