#251 Ohio WWTP Digester Dewatering

Facility managers at this WWTP had been contracting a firm with a portable belt press to dewater their biosolids. They sought new technology to reduce costs, use their own labor, and take control of the timing of the dewatering. WaterSolve, LLC performed a pilot study on site using Geotube® dewatering containers and Solve 137 emulsion polymer. They were able to use their own labor, existing drying beds, a chemical feed pump from the plant, and choose the days they wanted to dewater. The cost savings were substantial as well.
