This blog post will take you on a journey through the innovative processes, community benefits, and wider implications of this sustainable wastewater management solution.
The Challenge: Meeting New DNR Water Quality Limits
About four years ago, the Iowa Department of Natural Resources (DNR) notified city officials across the state about new limits on wastewater denitrification. This process, crucial for removing nitrogen from sewage and wastewater to improve water quality, was set to face more stringent regulations starting April 1st. For many small Iowa communities, these new limits posed a significant challenge, potentially leading to costly upgrades and increased utility costs for residents.
However, the city of Osage saw this challenge as an opportunity to innovate. Instead of merely complying with the new regulations, they sought a solution that would not only meet the DNR’s requirements but also benefit the community in multiple ways.
The Innovative Solution: A Collaborative Approach
The key to Osage’s success lies in an unexpected partnership between the city and a local business, Valent BioSciences. This collaboration has resulted in a wastewater treatment process that’s not only effective but also economically and environmentally beneficial.
- Carbon-Rich Waste as a Denitrification Catalyst: After two years of research, it was discovered that the carbon-rich waste from Valent BioSciences’ production of biorational agricultural products could significantly enhance the denitrification process.
- Community Partnership: The city’s wastewater treatment plant, unable to reach the DNR’s goals on its own, found a perfect partner in Valent BioSciences. This partnership has been described by Osage Mayor Steve Cooper as “kind of like a marriage” that’s “gone in the right direction.”
- Cost Reduction: Thanks to Valent BioSciences’ expertise and resources, the city’s wastewater treatment plant operates at a reduced cost, resulting in significant savings for the community.
This innovative approach showcases how small towns can turn environmental challenges into opportunities, fostering both economic growth and environmental protection.
The Denitrification Process: Turning Waste into a Valuable Resource
At the heart of Osage’s wastewater treatment innovation is the denitrification process. This crucial step in wastewater treatment removes nitrogen, a potential pollutant, from sewage and wastewater. Here’s how Osage has revolutionized this process:
- Carbon-Rich Waste Addition: The carbon-rich waste from Valent BioSciences’ production is added to the wastewater treatment process.
- Enhanced Bacterial Activity: This additional carbon source boosts the activity of denitrifying bacteria in the treatment system.
- Efficient Nitrogen Removal: The enhanced bacterial activity leads to more efficient conversion of nitrates into harmless nitrogen gas, which is released into the atmosphere.
- Improved Water Quality: The result is treated water with significantly lower nitrogen levels, meeting and even exceeding the Iowa DNR’s new water quality limits.
This process not only solves the immediate challenge of meeting regulatory requirements but also creates a valuable byproduct: nutrient-rich biosolids that can be used in agriculture.
Benefits for Farmers: Turning Sewage into Agricultural Gold
“Farmers receive bio solids from wastewater treatment containing three essential crop nutrients: nitrogen, phosphorus, and potassium.”
One of the most exciting aspects of Osage’s wastewater treatment innovation is its direct benefit to local farmers. The process doesn’t just clean water; it creates a valuable agricultural resource:
- Nutrient-Rich Biosolids: The treated waste produces biosolids rich in essential crop nutrients, including nitrogen, phosphorus, and potassium.
- Free Fertilizer Alternative: These biosolids are applied to local farmers’ fields, providing a free, sustainable alternative to commercial fertilizers.
- Improved Soil Health: Beyond providing nutrients, these biosolids can improve soil structure and water retention capacity.
- Reduced Fertilizer Costs: By using these biosolids, farmers can significantly reduce their expenditure on commercial fertilizers.
As Brian Lynch, Valent BioSciences facility manager, explains, “In conjunction with local farmers, we apply those biosolids to their fields. Which gives them valuable nitrogen, phosphorus, potassium and a lot of other different minerals, which makes your crops grow much better.”
This approach not only helps farmers but also closes the nutrient cycle, turning what was once considered waste into a valuable resource for sustainable agriculture.
Economic and Environmental Impact
The innovative wastewater treatment approach in Osage isn’t just good for the environment; it’s also having a significant positive economic impact:
- Reduced Utility Costs: Mayor Cooper proudly notes that there’s been only one increase in water utility costs in the past 10 years, a remarkable achievement given the rising costs in many other communities.
- Savings for the City: The implemented practices are saving the city more than $300,000, funds that can be redirected to other community needs.
- Economic Benefits for Farmers: Local farmers benefit from reduced fertilizer costs and potentially improved crop yields.
- Environmental Protection: By effectively removing nitrogen from wastewater, the process helps protect local water bodies from nutrient pollution.
This win-win situation demonstrates how environmental stewardship and economic benefits can go hand in hand when communities think creatively about resource management.
Community Collaboration: The Key to Success
The success of Osage’s wastewater treatment innovation hinges on the strong collaboration between the city and local businesses. This partnership approach offers valuable lessons for other communities facing similar challenges:
