Treatment includes preliminary, primary, <br />secondary, and tertiary processes. As a byproduct of the treatment process, the WQCP <br />generates approximately 100 wet tons per day (WTPD) of Class B dewatered digester sludge <br />(biosolids). Biosolids are hauled offsite and disposed of using agricultural land application; <br />however, since 1998, land application of Class B biosolids has become increasingly <br />controversial due to odor complaints and safety concerns. <br />15 -1 <br />
