Problem: The Big Creek Water Reclamation Facility in North Fulton County, Georgia, is the county’s largest in flow and service area. To accommodate population growth and economic development, the facility needed more capacity.

Solution: A phased expansion with multi-phase construction started in 2020 with expected completion in mid-2024. The project included a new dewatering building commissioned in May 2022 and including two Schwing Bioset FSP 1203 screw presses, designed to replace five smaller screw presses. Each new press can process 2,600 dry pounds per hour of aerobically digested biosolids, versus a previous maximum throughput of 550 dry pounds per hour.

Result: The presses operate 18 hours a day, five to six days a week. Five 25-ton trailers of biosolids are hauled to landfill daily. Hauling and landfill costs, electricity usage and maintenance all have been reduced. Each screw press operates at 50% of design capacity. The facility is ultimately designed for five FSP 1203 machines. 715-247-3433; www.schwingbioset.com
