ABSTRACT
This chapter describes some of the methods of achieving the visible benefit of the National Environmental Policy Act process. Add-on control devices may be defined as devices placed in the effluent stream such that the pollutant-bearing effluent enters and exits the device after depositing most of the pollutant in the device. Industrial in-plant liquid wastes are expected to be treated with in-plant control technologies to eliminate or reduce emissions in effluents before discharge to municipal systems by the industry. Compliance with the air pollution control regulations and emissions standards promulgated by the federal and state agencies often requires a substantial reduction, or occasionally elimination, of emissions from a source. Changing a process to reduce or eliminate air pollution has been successfully used in many industries including coal-fired power generation, petroleum refining, and agriculture. Fluidized-bed combustion is an available technology which should be considered as an alternative control technology.
