A publicly owned wastewater treatment facility in the southwest United States installed a direct-fired thermal oxidizer (DFTO) for the abatement of volatile organic compounds (VOCs) and other separated constituents from the wastewater treatment gas-separation process.

The 600 scfm Quadrant DFTO from Catalytic Products International (CPI) burns the tail gas from a digester gas conditioning, pressure-swing adsorption (PSA) system. The thermal oxidizer will destroy VOC emissions with more than 99 percent destruction rate efficiency, says the company.

CPI worked with the facility and its contractor to engineer, design and deliver the assembled DFTO, including exhaust stack, control panel and flame arrestor. CPI also provided installation supervision and equipment startup.
