Sugar Creek WWTP Screw Press Records Impressive Data

 

Written by Tom Welch, November 2018

The Sugar Creek WWTP, owned by the Sangamon County Water Reclamation District located in Springfield, IL, has two Schwing Bioset model FSP 1102 screw presses and our Class B alkaline stabilization process. The screw presses dewater the plant’s aerobically treated biosolids and the downstream equipment produces the alkaline stabilized Class B biosolids. These biosolids are then windrowed in the District’s storage shed and eventually land applied for beneficial use. Data recorded from a recent site visit on a single screw press in operation was impressive and can be seen below.

Incoming Flow: 280 gpm
Incoming % DS: 1.5%
Throughput: 2,100 lbsdry/hr
Polymer Dose: 12 lbs/ton
Output % DS: 22%

Check out the included photos and operational videos, which show an overview of the installation and the equipment in action.
