For the City of Perham, the SEH project team assessed the economic, technical, and environmental benefits of converting industrial processing and agricultural waste into the most cost-effective energy form. SEH identified industrial wastewater streams within the area and developed a test plan. The test plan included operating bench-scale test reactors for the wastewater streams in two stages. Stage I  addressed the biodegradation characteristics and biochemical methane potential (BMP) for using anaerobic processes for treating each individual industrial waste.

In Stage II, we are identifying the wastes that contain favorable anaerobic biodegradation characteristics and blending in appropriate ratios to provide the anticipated composition for full-scale design and operation. In addition, SEH is detailing the economic feasibility and profitability of using the methane from the treatment process as a renewable energy source.
