Loganville, Ga,

In 2016, the City of Loganville, Georgia installed BCR’s CleanB® solution at its 1.5 MGD wastewater treatment plant. Prior to the CleanB® installation, the facility used a sequence batch reactor (SBR) followed by a digester. Due to strong residential growth rates in the area, the facility had to plan for a significant increase in their average daily flow. The estimated flow increase would far exceed their digester capacity and put the City at risk of meeting Class B disinfection requirements. The facility also brings in septic sludge periodically and had issues with odors both at the facility and disposition sites.

 

The decision to install a CleanB® system addressed capacity, regulatory, and odor concerns. Currently, the facility uses the existing digester (fed from the SBR) as a pass-through “wide-spot” to feed the CleanB® system, which allows for operational flexibility. The CleanB® consistently meets Class B and VAR requirements, and the dewatered end-product is beneficially reused. The treated WAS is dewatered using an existing Centrysis centrifuge. In addition to eliminating foul odors, increasing capacity and decreasing regulatory risks, the facility has realized significant costs savings due to: 1) significantly lowering the digester blower output, 2) decreased polymer consumption and 3) increasing cake solids from 18% to 22%, significantly reducing hauling and disposition costs.
