The King's Landing Wastewater Treatment Plant treats industrial sewer wastewater from nearly 200 manufacturing buildings for Eastman Kodak Company located at Kodak Park in Rochester, NY. The average throughput for the facility is 28 million gallons of wastewater per day (MGD) and discharges the resulting effluent into the Genesee River. Through a series of physical, chemical, and biological treatment processes, materials are removed from the wastewater and sludge is produced. The sludge is conveyed through a belt press for dewatering prior to incineration. The dewatered sludge is sent to a multiple hearth incinerator with a secondary combustion chamber/afterburner for thermal treatment. From the combustion and incineration process, off-gases are produced. Therefore, air pollution control equipment is needed to treat the gas stream. At King's Landing, an induced draft fan creates negative pressure through the hearth along with a series of air pollution control equipment (APCE) consisting of a quench chamber, condenser/scrubber, venturi, entrainment separator, and a wet electrostatic precipitator (WESP). This equipment captures the components in the air stream through processes such as gas saturation, caustic neutralization, and electron particle collection. The WESP is a device that is used for fine particle collection in the range of 1 micron or less. Upon entereing the unit, the particles in the gas stream are given a charge. The particles accumulate on the surface of the WESP and are periodically flushed out and collected in the wash water. The efficiency of particles removed from the WESP can be indirectly correlated by the power value measured in KVA (kilovolt amps). As the power decreases, the particulate collection efficiency is lowered. This is due to the increased resistance in the system. Although there is system variability, the King's Landing multiple hearth incinerator and associated air pollution control equipment operates in accordance with all relevant environmental standards. The purpose of this thesis is to use statistical analysis tools to determine the significant variables that affect the performance and efficiency of the WESP. The WESP is the last unit in the air pollution control equipment (APCE) system at King's Landing. Since the WESP is the final air-polishing device in the system, its optimal performance is critical. The WESP is subject to the most variability from the upstream APCE as well as the combustion process because it is the final unit in the system. This paper will analyze multiple predictor variables, which are inputs into the WESP, and determine their significance on the power reading that will serve as the response variable.
