STARTUP AND INITIAL OPERATIONAL PROCEDURES FOR ACTIVATED SLUDGE FACILITIES FOR TREATMENT OF A COMPLEX WASTEWATER Gary M. Davis, .Project Manager Carl E. Adams, Jr., President Associated Water and Air Resources Engineers, Inc. Nashville, Tennessee 37204 INTRODUCTION The major objective of this chapter is to provide discussion of considerations and factors to be evaluated in initiating an activated sludge plant. Startup of industrial activated sludge systems no longer involves dumping municipal waste-activated sludge into the aeration basin and treating a split stream until the treatment plant stabilizes. Bypassing wastewater is no longer a part of startup; the startup program must be fully developed in advance so that an unexpected upset of the treatment plant does not shut down the production unit. An activated sludge plant can be started up at the design mixed liquor volatile suspended solids concentration, or with sufficient sludge for lower or higher initial suspended solids. Aeration basins can be started up partially or completely filled. A basin can be gradually filled using treated surplus feed, acclimation chemical wastes or the plant wastewater. These alternative startup modes are discussed in this chapter. A recommended outline for developing a startup program for an activated sludge plant is shown in Figure 1.
