Addigest: Revolutionizing Wastewater Treatment with Extended Aeration

The Challenge: Wastewater treatment plants face a constant challenge: effectively removing pollutants while minimizing energy consumption and operational costs. Traditional methods often struggle to meet these demands, especially in situations with high organic loads or fluctuating influent characteristics. Enter Addigest, a game-changer in the wastewater treatment industry.

Addigest: A Unique Approach to Wastewater Treatment

Addigest is not a single technology but a holistic approach to wastewater treatment built around the Smith & Loveless, Inc. Extended Aeration Package Plant. This system leverages the power of anaerobic digestion in a unique way, incorporating it into the existing extended aeration process.

The Key Advantages of Addigest:

• Enhanced Nutrient Removal: Addigest boasts superior nutrient removal capabilities, particularly for phosphorus and nitrogen, surpassing traditional methods. This translates to cleaner water discharge and reduced environmental impact.
• Energy Efficiency: The anaerobic digestion process generates biogas, which can be used to power the treatment plant itself, significantly reducing energy consumption and operational costs.
• Increased Sludge Reduction: The Addigest system dramatically reduces the amount of sludge produced, minimizing disposal costs and environmental burden.
• Improved Biosolids Quality: The biosolids produced by the Addigest process are of higher quality, making them suitable for beneficial reuse as fertilizer or soil amendment.

How Addigest Works:

The Addigest system combines the benefits of extended aeration with anaerobic digestion. Here's how it works:

1. Extended Aeration: Wastewater undergoes aerobic treatment in a specially designed basin where microorganisms consume organic pollutants and release energy.
2. Anaerobic Digestion: A portion of the treated wastewater is diverted to an anaerobic digester, where microorganisms break down organic matter in the absence of oxygen. This process generates biogas, which can be used for energy production.
3. Nutrient Removal: The anaerobic digestion process removes nutrients like phosphorus and nitrogen, further enhancing the overall treatment efficiency.
4. Sludge Reduction: The digester reduces the volume of sludge, making it easier to manage and reducing disposal costs.

The Benefits Extend Beyond the Plant:

Addigest delivers tangible benefits to communities and the environment:

• Improved Water Quality: The enhanced nutrient removal significantly reduces the amount of pollutants released into water bodies, leading to healthier aquatic ecosystems.
• Reduced Greenhouse Gas Emissions: By utilizing biogas for energy generation, Addigest helps reduce dependence on fossil fuels and minimizes greenhouse gas emissions.
• Sustainable Resource Management: Addigest promotes resource recovery by using biosolids as fertilizer and biogas as an energy source, closing the loop on waste management.

Addigest: A Sustainable Solution for the Future

The Addigest approach represents a significant step forward in wastewater treatment technology. It offers a sustainable, cost-effective, and environmentally responsible solution for communities seeking to achieve the highest standards of water quality while minimizing their environmental footprint. As the world continues to grapple with environmental challenges, Addigest provides a clear path toward a more sustainable future.
