Clayton County Facility – Biosolids Handling System

Improved Biosolids Management with Flexible Conveyor Routing

Location: Clayton County, Georgia

Clayton County’s wastewater facility needed a cost-effective way to manage biosolids within constrained plant space. Serpentix conveyors were implemented to move material through multiple transfer points and around obstacles without requiring additional structural changes. This upgrade reduced operational challenges, improved plant efficiency, and provided long-term flexibility for expanding treatment needs.

Challenges

High cost of natural gas for sludge drying
Need for alternative fuel from fast-growing softwood
Precise chip handling across incline paths and tight building layout
Weatherproofing materials delivery to prevent incinerator downtime

Serpentix Solutions

71'6" metal pan conveyor moves wood chips from receiving bin to a 170-ton supply hopper

107'4" conveyor transfers chips into the incinerator’s ram feed system via a 3D inclined path

Oscillating bins and unloading vans ensure steady flow even in adverse conditions

Modular conveyors reduced reliance on multiple transfer points and minimized footprint

Results

Reduced fuel cost using harvested loblolly chips

107'4" conveyor transfers chips into the incinerator’s ram feed system via a 3D inclined path

Enabled CCWA’s transformation into one of the most innovative municipal wastewater and land treatment systems in the US

Improved environmental sustainability and energy independence
