Problem: The Big Creek Water Reclamation Facility, the largest clean-water plant in Fulton County, Georgia, needed additional capacity to accommodate growth.

Solution: A multiphase expansion from 32 mgd to 38 mgd is to be completed mid-2024. A new dewatering building features some of the largest screw presses in North America. It includes two Schwing Bioset FSP 1203 screw presses, each with a 1,200 mm screw diameter for throughput of 2,600 dry pounds per hour of aerobically digested biosolids. These new presses replace five smaller screw presses. 

Result: The machines, with high-performance screens, improved dewatering performance and provide significant savings in hauling costs and landfill tipping fees. They reduced electricity usage and maintenance. 715-247-3433; www.schwingbioset.com
