Innovative solutions in wastewater are not limited to treatment plants in big cities. Small or midsized operations can be progressive as well.
The Russellville (Arkansas) Pollution Control Works Facility was faced with a challenge when its Class B biosolids no longer could be land-applied. Rather than commit long-term to landfilling the material, plant officials explored alternatives and decided to upgrade to a Class A product.
They chose lime stabilization using the Schwing Bioset process. Since 2016, the facility now processes an average 81,000 pounds of Class A material per month for distribution to farmers at no charge.
