HIGH-TEMPERATURE EFFECTS ON THE ACTIVATED SLUDGE PROCESS TREATING INDUSTRIAL WASTEWATERS Michael L. Duke, Senior Project Engineer Michael E. Templeton, Engineer W. Wesley Eckenfelder, Jr., Chairman of the Board AWARE, Inc. Nashville, Tennessee 37235 Joe C. Stowe, Jr., Facilities Director Hopewell Regional Wastewater Treatment Facility Hopewell, Virginia 23860 The City of Hopewed operates a combined municipal/industrial wastewater treatment plant in Hopewell, Virginia. The treatment plant utilizes the pure oxygen activated sludge process to treat the wastewater generated by four industries, the City of Hopewed and Fort Lee. The treatment facility also receives an aluminum hydroxide-mixed particulate sludge from a local water treatment plant. AWARE completed a facility evaluation in March 1979. One major conclusion of the evaluation was that over a significant portion of the year, the aeration basin temperatures reach levels above those generally acceptable for biological treatment. OBJECTIVES OF INVESTIGATION AWARE was retained by the Regional Facility to determine the effects of these high temperatures on treatment efficiency. Specifically, the objectives of the studies were to: 1. determine the optimum operating temperature; 2. define the maximum operating temperature; 3. determine the feasibility of operating the existing system in a thermophilic mode; and 4. determine maximum organic loading capabilities. SCOPE OF PROJECT The pilot study consisted of a series of experiments designed to test the effects of temperature on biological treatment. The experimental phases were: (a) acclimation and start-up; and (b) analysis of temperature effect on the rate of BOD removal, effluent TSS, and clarification. PROJECT IMPLEMENTATION The entirety of the investigation was conducted at the Regional Facility. Operational and performance monitoring tests were conducted by AWARE personnel. Analytical support was provided by the Hopewed Regional Facility Laboratory. EXPERIMENTAL PROCEDURES The study was divided into two tasks: (a) analysis of the effect of temperature on the rate of soluble BOD removal; and (b) determination of the effect of temperature on solids separation. 817
