Description:
The performance of three new anaerobic biological treatment technologies were compared and evaluated. Data were obtained from the operation of pilot plants representative of the anaerobic filter, anaerobic upflow sludge bed, and anaerobic fluidized bed. A review of recent literature presents information on these technologies developed in laboratory, pilot-scale and full-scale plants. The wastewater selected for the study was the evaporator foul condensate from an ammonia-based sulfite pulping mill at Procter and Gamble's Mehoopany, Pennsylvania plant. During pilot plant construction, laboratory screening studies were conducted to determine wastewater characteristics and anaerobic treatability. The pilot plants were operated for seven months. Results indicated that the anaerobic fluidized bed performance was excellent, achieving high COD removals of 70 to 90 percent at reactor volumetric loadings from 7 to 100 kg/sq m/day.
